Such a model includes two probabilistic components, the first reflecting the association between a geologic condition (structural closure, for example) and the occurrence of oil, and the second reflecting the uncertainty associated with the estimation of geologic variables in areas of limited control. Estimates of the conditional relationship between geologic variables and subsequent production can be found by analyzing the exploration history of a \"training area\" judged to be geologically similar to the exploration area. The geologic variables are assessed over the training area using an historical subset of the available data, whose density corresponds to the present control density in the exploration area. The success or failure of wells drilled in the training area subsequent to the time corresponding to the historical subset provides empirical estimates of the probability of success conditional upon geology. Uncertainty in perception of geological conditions may be estimated from the distribution of errors made in geologic assessment using the historical subset of control wells. These errors may be expressed as a linear function of distance from available control. Alternatively, the uncertainty may be found by calculating the semivariogram of the geologic variables used in the analysis: the two procedures will yield approximately equivalent results. The empirical probability functions may then be transferred to the exploration area and used to estimate the likelihood of success of specific exploration plays. These estimates will reflect both the conditional relationship between the geological variables used to guide exploration and the uncertainty resulting from lack of control. The technique is illustrated with case histories from the mid-Continent area of the U.S.A. ?? 1977 Plenum Publishing Corp.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of the International Association for Mathematical Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Kluwer Academic Publishers-Plenum Publishers","doi":"10.1007/BF02047411","issn":"00205958","usgsCitation":"Davis, J., 1977, Estimation of the probability of success in petroleum exploration: Journal of the International Association for Mathematical Geology, v. 9, no. 4, p. 409-427, https://doi.org/10.1007/BF02047411.","startPage":"409","endPage":"427","numberOfPages":"19","costCenters":[],"links":[{"id":204901,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF02047411"},{"id":218981,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"9","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0bb7e4b0c8380cd52849","contributors":{"authors":[{"text":"Davis, J.C.","contributorId":72121,"corporation":false,"usgs":true,"family":"Davis","given":"J.C.","email":"","affiliations":[],"preferred":false,"id":357479,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":2052,"text":"wsp2044 - 1977 - Modeling chloride movement in the alluvial aquifer at the Rocky Mountain Arsenal, Colorado","interactions":[],"lastModifiedDate":"2023-04-17T21:01:47.597359","indexId":"wsp2044","displayToPublicDate":"1977-01-01T00:00:00","publicationYear":"1977","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":341,"text":"Water Supply Paper","code":"WSP","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"2044","title":"Modeling chloride movement in the alluvial aquifer at the Rocky Mountain Arsenal, Colorado","docAbstract":"A solute-transport model that can be used to predict the movement of dissolved chemicals in flowing ground water was applied to a problem of ground-water contamination at the Rocky Mountain Arsenal, near Denver, Colo. The model couples a finite-difference solution to the ground-water flow equation with the method-of-characteristics solution to the solute-transport equation. \r\n\r\nFrom 1943 to 1956 liquid industrial wastes containing high chloride concentrations were disposed into unlined ponds at the Arsenal. Wastes seeped out of the unlined disposal ponds and spread for many square miles in the underlying shallow alluvial aquifer. Since 1956 disposal has been into an asphalt-lined reservoir, which contributed to a decline in ground-water contamination by 1972. The simulation model quantitatively integrated the effects of the major factors that controlled changes in chloride concentrations and accurately reproduced the 30-year history of chloride ground-water contamination. \r\n\r\nAnalysis of the simulation results indicates that the geologic framework of the area markedly restricted the transport and dispersion of dissolved chemicals in the alluvium. Dilution, from irrigation recharge and seepage from unlined canals, was an important factor in reducing the level of chloride concentrations downgradient from the Arsenal. Similarly, recharge of uncontaminated water from the unlined ponds since 1956 has helped to dilute and flush the contaminated ground water.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wsp2044","usgsCitation":"Konikow, L.F., 1977, Modeling chloride movement in the alluvial aquifer at the Rocky Mountain Arsenal, Colorado: U.S. Geological Survey Water Supply Paper 2044, v, 43 p., https://doi.org/10.3133/wsp2044.","productDescription":"v, 43 p.","costCenters":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"links":[{"id":27579,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wsp/2044/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":138443,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wsp/2044/report-thumb.jpg"},{"id":415889,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_25388.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Colorado","otherGeospatial":"Rocky Mountain Arsenal","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"coordinates\": [\n [\n [\n -104.7864619925063,\n 39.87200017342937\n ],\n [\n -104.90544337744733,\n 39.87200017342937\n ],\n [\n -104.90544337744733,\n 39.79752238121182\n ],\n [\n -104.7864619925063,\n 39.79752238121182\n ],\n [\n -104.7864619925063,\n 39.87200017342937\n ]\n ]\n ],\n \"type\": \"Polygon\"\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db69994b","contributors":{"authors":[{"text":"Konikow, Leonard F. 0000-0002-0940-3856 lkonikow@usgs.gov","orcid":"https://orcid.org/0000-0002-0940-3856","contributorId":158,"corporation":false,"usgs":true,"family":"Konikow","given":"Leonard","email":"lkonikow@usgs.gov","middleInitial":"F.","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":144599,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":70042912,"text":"70042912 - 1976 - Rise of a variable-viscosity fluid in a steadily spreading wedge-shaped conduit with accreting walls","interactions":[{"subject":{"id":14563,"text":"ofr74251 - 1974 - Rise of a variable viscosity fluid in a steadily spreading wedge-shaped conduit with accreting walls","indexId":"ofr74251","publicationYear":"1974","noYear":false,"title":"Rise of a variable viscosity fluid in a steadily spreading wedge-shaped conduit with accreting walls"},"predicate":"SUPERSEDED_BY","object":{"id":70042912,"text":"70042912 - 1976 - Rise of a variable-viscosity fluid in a steadily spreading wedge-shaped conduit with accreting walls","indexId":"70042912","publicationYear":"1976","noYear":false,"title":"Rise of a variable-viscosity fluid in a steadily spreading wedge-shaped conduit with accreting walls"},"id":1}],"lastModifiedDate":"2022-06-15T14:42:26.277635","indexId":"70042912","displayToPublicDate":"2013-01-01T00:00:00","publicationYear":"1976","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2446,"text":"Journal of Research of the U.S. Geological Survey","active":true,"publicationSubtype":{"id":10}},"title":"Rise of a variable-viscosity fluid in a steadily spreading wedge-shaped conduit with accreting walls","docAbstract":"Relatively rigid plates making up the outer 50 to 100 km of the Earth are steadily separating from one another along narrow globe-circling zones of submarine volcanism, the oceanic spreading centers. Continuity requires that the viscous underlying material rise beneath spreading centers and accrete onto the steadily diverging plates. It is likely that during the rise the viscosity changes systematically and that the viscous tractions exerted on the plates contribute to the unique pattern of submarine mountains and earthquake faults observed at spreading centers. The process is modeled by viscous creep in a wedge-shaped conduit (with apex at the sea floor) in which the viscosity varies as rm where r is distance from the apex and m is a parameter. For these conditions, the governing differential equations take a simple form. The solution for the velocity is independent of r and of the sign of m. As viscous stresses vary as rm-1, the pattern of stress on the conduit wall is sensitive to viscosity variation. For negative m, the viscous pressure along the base of the conduit is quite uniform; for positive m, it falls toward zero in the axial region as the conduit base widens. For small opening angles, viscous forces push the plates apart, and for large ones, they oppose plate separation. Though highly idealized, the solution provides a tool for investigating tectonic processes at spreading centers.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","usgsCitation":"Lachenbruch, A.H., and Nathenson, M., 1976, Rise of a variable-viscosity fluid in a steadily spreading wedge-shaped conduit with accreting walls: Journal of Research of the U.S. Geological Survey, v. 4, no. 2, p. 181-188.","productDescription":"8 p.","startPage":"181","endPage":"188","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true},{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":266647,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":266646,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/journal/1976/vol4issue2/report.pdf","text":"Report","linkFileType":{"id":1,"text":"pdf"},"description":"Report"}],"volume":"4","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5108fd91e4b0d965cd9f237e","contributors":{"authors":[{"text":"Lachenbruch, Arthur H.","contributorId":27850,"corporation":false,"usgs":true,"family":"Lachenbruch","given":"Arthur","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":472580,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nathenson, Manuel 0000-0002-5216-984X mnathnsn@usgs.gov","orcid":"https://orcid.org/0000-0002-5216-984X","contributorId":1358,"corporation":false,"usgs":true,"family":"Nathenson","given":"Manuel","email":"mnathnsn@usgs.gov","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":472579,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70042717,"text":"70042717 - 1976 - Digital-model analysis of the effects of water-use alternatives on spring discharges Gooding and Jerome Counties, Idaho","interactions":[{"subject":{"id":15062,"text":"ofr75615 - 1975 - Digital-model analysis of the effects of water-use alternatives on spring discharges, Gooding and Jerome Counties, Idaho","indexId":"ofr75615","publicationYear":"1975","noYear":false,"title":"Digital-model analysis of the effects of water-use alternatives on spring discharges, Gooding and Jerome Counties, Idaho"},"predicate":"SUPERSEDED_BY","object":{"id":70042717,"text":"70042717 - 1976 - Digital-model analysis of the effects of water-use alternatives on spring discharges Gooding and Jerome Counties, Idaho","indexId":"70042717","publicationYear":"1976","noYear":false,"title":"Digital-model analysis of the effects of water-use alternatives on spring discharges Gooding and Jerome Counties, Idaho"},"id":1}],"lastModifiedDate":"2013-01-18T14:10:29","indexId":"70042717","displayToPublicDate":"2013-01-01T00:00:00","publicationYear":"1976","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":4,"text":"Other Government Series"},"seriesTitle":{"id":301,"text":"Water Information Bulletin","active":false,"publicationSubtype":{"id":4}},"seriesNumber":"42","title":"Digital-model analysis of the effects of water-use alternatives on spring discharges Gooding and Jerome Counties, Idaho","docAbstract":"Springs discharging from the Snake Plain aquifer contribute approximately 6,000 cubic feet per second (170 cubic metres per second) to flow in the Snake River between Milner and King Hill.

The Survey estimates that fields discovered in Alaska through 1972 ultimately may produce about 26 billion bbl of oil and 68 Tcf of natural gas. In northern Alaska, Paleozoic and Mesozoic shelf and slope carbonate and clastic rocks of the Brooks Range orogen were thrust relatively northward over the depressed south margin of the Paleozoic and Mesozoic Arctic platform. A foredeep, the Colville geosyncline, developed across the depressed margin of the platform in earliest Cretaceous time. Detritus from the Brooks Range filled the foredeep and prograded northward to fill the Cretaceous and Tertiary North Chukchi and Umiat-Camden basins and form the progradational Beaufort shelf. The largest petroleum reserves (Prudhoe Bay and associated fields) and the best prospects for additional large discoveries in Alaska lie in the areally extensive upper Paleozoic to Tertiary carbonate and clastic rocks of northern Alaska. In southern Alaska, a series of arc-trench systems developed on oceanic rocks during Jurassic and Cretaceous time. Between these arcs and the metamorphic (continental) terranes of east-central and northern Alaska, large back-arc and arc-trench gap basins received thick volcanic and detrital deposits. These deposits were extensively, and commonly intensely, deformed and disrupted by mid-Jurassic to Tertiary plutonism, Laramide oroclinal bending, wrench faulting, and arc-related compression. This deformation, coupled with low porosity (in part produced by diagenetic mobilization of labile constituents), has left these rocks with only modest, local prospects for petroleum. Laramide events compressed and consolidated (\"continentalized\") the late Mesozoic back-arc basin deposits and welded them to the older continental terranes on the north and east. Subsequent sedimentation was localized and nonmarine except in onshore and offshore coastal basins, where thick sections of mixed marine and nonmarine Tertiary sediments accumulated. The Aleutian arc and the associated Queen Charlotte transform-fault system have dominated structural and depositional patterns in southern Alaska, including many of the Tertiary coastal basins, since the early Cenozoic. The Tertiary coastal basins are areally extensive, and in some areas contain many large folds. They are known to be petroliferous in Bristol Bay and the Gulf of Alaska, and to contain major accumulations of oil and gas at Cook Inlet, but they are relatively little explored.","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Circum-Pacific energy and mineral resources (AAPG Memoir 25)","largerWorkSubtype":{"id":3,"text":"Organization Series"},"language":"English","publisher":"AAPG","publisherLocation":"Tulsa, OK","usgsCitation":"Grantz, A., and Kirschner, C., 1976, Tectonic framework of petroliferous rocks in Alaska: hydrocarbons, chap. of Circum-Pacific energy and mineral resources (AAPG Memoir 25), p. 291-307.","productDescription":"17 p.","startPage":"291","endPage":"307","costCenters":[{"id":255,"text":"Energy Resources Program","active":true,"usgs":true}],"links":[{"id":266659,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":266658,"type":{"id":15,"text":"Index Page"},"url":"https://archives.datapages.com/data/specpubs/mineral1/data/a175/a175/0001/0250/0291.htm"}],"country":"United States","state":"Alaska","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 172.5,51.2 ], [ 172.5,71.4 ], [ -130.0,71.4 ], [ -130.0,51.2 ], [ 172.5,51.2 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5108fd95e4b0d965cd9f2393","contributors":{"authors":[{"text":"Grantz, Arthur agrantz@usgs.gov","contributorId":2585,"corporation":false,"usgs":true,"family":"Grantz","given":"Arthur","email":"agrantz@usgs.gov","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":472602,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kirschner, C.E.","contributorId":81107,"corporation":false,"usgs":true,"family":"Kirschner","given":"C.E.","email":"","affiliations":[],"preferred":false,"id":472603,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70043109,"text":"70043109 - 1976 - Electronic thermal sensor and Data Collection Platform technology: Part 5 in Thermal surveillance of active volcanoes using the Landsat-1 Data Collection System","interactions":[{"subject":{"id":10744,"text":"ofr7787 - 1977 - Electronic thermal sensor and Landsat data collection platform technology","indexId":"ofr7787","publicationYear":"1977","noYear":false,"title":"Electronic thermal sensor and Landsat data collection platform technology"},"predicate":"SUPERSEDED_BY","object":{"id":70043109,"text":"70043109 - 1976 - Electronic thermal sensor and Data Collection Platform technology: Part 5 in Thermal surveillance of active volcanoes using the Landsat-1 Data Collection System","indexId":"70043109","publicationYear":"1976","noYear":false,"title":"Electronic thermal sensor and Data Collection Platform technology: Part 5 in Thermal surveillance of active volcanoes using the Landsat-1 Data Collection System"},"id":1}],"lastModifiedDate":"2013-02-05T12:00:58","indexId":"70043109","displayToPublicDate":"2013-01-01T00:00:00","publicationYear":"1976","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":6,"text":"USGS Unnumbered Series"},"seriesTitle":{"id":360,"text":"Final Report","active":false,"publicationSubtype":{"id":6}},"title":"Electronic thermal sensor and Data Collection Platform technology: Part 5 in Thermal surveillance of active volcanoes using the Landsat-1 Data Collection System","docAbstract":"Five Data Collection Platforms (DCP) were integrated electronically with thermall sensing systems, emplaced and operated in an analog mode at selected thermally significant volcanic and geothermal sites.

In harsh, windy, high-altitude volcanic environments the DCP functioned best with a small dipole antenna. Sixteen kg of alkaline batteries provided a viable power supply for the DCP systems, operated at a low-duty cycle, for 5 to 8 months. A proposed solar power supply system would lengthen the period of unattended operation of the system considerably. Special methods of data handling such as data storage via a proposed memory system would increase the significance of the twice-daily data reception enabling the DCP's to record full diurnal-temperature cycles at volcanic or geothermal sites. Refinements in the temperature-monitoring system designed and operated in experiment SR 251 included a backup system consisting of a multipoint temperature scanner, a servo mechanism and an analog-to-digital recorder.

The silt fraction is the highly dominant component of the mud blanket; silt appears to be hydraulically trapped within the shelf environment and constitutes the most abundant detrital component within the Outer Continental Shelf region. The subordinate clay component of the mud blanket is concentrated toward the shelf break and may be largely escaping into deeper water environments.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","usgsCitation":"Shideler, G.L., 1976, Textural distribution of sea-floor sediments, south Texas Outer Continental Shelf: Journal of Research of the U.S. Geological Survey, v. 4, no. 6, p. 703-713.","productDescription":"11 p.","startPage":"703","endPage":"713","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"links":[{"id":266234,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":266227,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/journal/1976/vol4issue6/report.pdf","text":"Report","size":"20.3 MB","linkFileType":{"id":1,"text":"pdf"},"description":"Report"}],"country":"United States","state":"Texas","otherGeospatial":"Texas Outer Continental Shelf","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -97.72,25.84 ], [ -97.72,30.0 ], [ -93.52,30.0 ], [ -93.52,25.84 ], [ -97.72,25.84 ] ] ] } } ] }","volume":"4","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50ffc323e4b0ca65fed0d2b1","contributors":{"authors":[{"text":"Shideler, Gerald L.","contributorId":89137,"corporation":false,"usgs":true,"family":"Shideler","given":"Gerald","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":472134,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":70043031,"text":"70043031 - 1976 - Gravity and magnetic studies of the Geysers-Clear Lake geothermal region, California, USA","interactions":[{"subject":{"id":14265,"text":"ofr75368 - 1975 - Gravity and magnetic studies of The Geysers-Clear Lake geothermal region, California","indexId":"ofr75368","publicationYear":"1975","noYear":false,"title":"Gravity and magnetic studies of The Geysers-Clear Lake geothermal region, California"},"predicate":"SUPERSEDED_BY","object":{"id":70043031,"text":"70043031 - 1976 - Gravity and magnetic studies of the Geysers-Clear Lake geothermal region, California, USA","indexId":"70043031","publicationYear":"1976","noYear":false,"title":"Gravity and magnetic studies of the Geysers-Clear Lake geothermal region, California, USA"},"id":1}],"lastModifiedDate":"2013-01-31T11:10:00","indexId":"70043031","displayToPublicDate":"2013-01-01T00:00:00","publicationYear":"1976","noYear":false,"publicationType":{"id":24,"text":"Conference Paper"},"publicationSubtype":{"id":19,"text":"Conference Paper"},"title":"Gravity and magnetic studies of the Geysers-Clear Lake geothermal region, California, USA","docAbstract":"Gravity and magnetic fields in The Geysers-Clear Lake region are interpreted in relation to the known geology and other available geophysical data. New gravity data provide additional detail with the area of geothermal steam production. Computer techniques were used for removal of the regional gravity field, anomaly enhancement, and modeling subsurface structures. The gravity field was separated into three components: (1) a regional field presumed to be due to deep crustal structure related to the continental margin; (2) a residual gravity low of approximately 30 mgal centered over Mount Hannah and having an approximate diameter of 20 km, which is caused, according to our model, by a magma chamber whose top lies within 10 km of the surface; and (3) a closed residual low over the original steam production field. This low is probably related to effects within 1.5 km of the surface and was modeled as a steam-saturated reservoir structure. Local magnetic highs correlate with surface outcrops of serpentinite and relief on the volcanic rocks. Upward continuation of the aeromagnetic data suggests that the serpentinite body along the Collayomi fault may extend to a depth of more than 3 km near Boggs Mountain, but that other serpentinite bodies are probably more shallow. A long-wavelength magnetic high (centered at ~39°03'N 122°33'W) and a magnetic low (centered at ~38°:43'N 122°47'W) give half-width depth estimates of about 10 km. The center of the Mount Hannah gravity low lies in an area between these features and appears devoid of deep magnetic expression.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings: second United Nations Symposium on the development and use of geothermal resources, San Francisco, California, USA, 20-29 May 1975","largerWorkSubtype":{"id":12,"text":"Conference publication"},"language":"English","publisher":"U.S. Energy Research and Development Administration","publisherLocation":"Washington, D.C.","usgsCitation":"Isherwood, W., 1976, Gravity and magnetic studies of the Geysers-Clear Lake geothermal region, California, USA, in Proceedings: second United Nations Symposium on the development and use of geothermal resources, San Francisco, California, USA, 20-29 May 1975, v. 2, p. 1065-1073.","productDescription":"9 p.","startPage":"1065","endPage":"1073","costCenters":[{"id":255,"text":"Energy Resources Program","active":true,"usgs":true}],"links":[{"id":266800,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -124.41,32.53 ], [ -124.41,42.0 ], [ -114.13,42.0 ], [ -114.13,32.53 ], [ -124.41,32.53 ] ] ] } } ] }","volume":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"510ba08ae4b0947afa3c85ac","contributors":{"authors":[{"text":"Isherwood, William F.","contributorId":71547,"corporation":false,"usgs":true,"family":"Isherwood","given":"William F.","affiliations":[],"preferred":false,"id":472806,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":70039211,"text":"70039211 - 1976 - Man against volcano: The eruption on Heimaey, Vestmann Islands, Iceland","interactions":[],"lastModifiedDate":"2012-07-27T01:01:50","indexId":"70039211","displayToPublicDate":"2012-01-01T09:12:46","publicationYear":"1976","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":6,"text":"USGS Unnumbered Series"},"seriesTitle":{"id":362,"text":"General Information Product","active":false,"publicationSubtype":{"id":6}},"title":"Man against volcano: The eruption on Heimaey, Vestmann Islands, Iceland","docAbstract":"The U.S. Geological Survey carries out scientific studies in the geological, hydrological, and cartographic sciences generally within the 50 states, but also in cooperation with scientific organizations in many foreign countries for the investigation of unusual earth science phenomena throughout the world. The following material discusses the impact of the 1973 volcanic eruption of Eldfell on the fishing port of Vestmannaeyjar on the island of Heimaey, Iceland. Before the eruption was over, approximately one-third of the town of Vestmannaeyjar had been obliterated but, more importantly, the potential damage had been reduced markedly by the spraying of seawater onto the advancing lava flows, causing them to be slowed, stopped, or diverted from the undamaged portion of the town. The Survey's interest and involvement in the Heimaey eruption in Iceland was occasioned by the possibility that the procedures used to control the course of the flowing lava and to reduce the damage in a modern town may some day be needed in Hawaii and possibly even in the continental United States. This publication is based on the observations of two USGS geologists, Richard S. Williams, Jr. and James G. Moore, as well as on information from the Icelandic Ministry for Foreign Affairs, Icelandic scientists' reports through the Center for Short-Lived Phenomena, and other published scientific reports. A number of Icelandic scientists studied the scientific aspects of the eruption and the engineering aspects of the control of lava flows, in particular, Professors Thorbjb'rn Sigurgeirsson and Sigurdur Thorarinsson of the University of Iceland Science Institute.

Twelve whole-rock samples of volcanic rocks and a composite of 11 basanitoid samples from Ross Island and vicinity, Antarctica show a narrow range of 87Sr/86Sr ratios from 0.70305 to 0.70339. This range is consistent with a model of differentiation from a single parent magma, but the data allow a 30% variation in the 87Rb/86Sr ratio in the source region if the average ratio is less than 0.057 and if the source region has existed as a closed system for 1.5 b.y. Megacrysts of titaniferous augite, kaersutite, and anorthoclase are isotopically indistinguishable from the host volcanic rocks and therefore are probably cogenetic with the volcanic sequence. A single trachyte sample is isotopically distinct from the rest of the volcanic rocks and probably was contaminated with crustal strontium.

Ultramafic and mafic nodules found in association with basanitoids and trachybasalts have 87Sr/86Sr ratios ranging from 0.70275 to 0.70575. Several of these nodules exhibit evidence of reaction with the melt and are isotopically indistinguishable from their hosts, but data for seven granulite-facies nodules show an apparent isochronal relationship. Although this isochron may be fortuitous, the resulting age of 158±22 m.y. is similar to ages reported for the voluminous Ferrar Dolerites, and suggests isotopic re-equilibration within the lower crust and upper mantle. These nodules are not genetically related to the Ferrar Dolerites, as evidenced by their lower initial 87Sr/86Sr ratios.

Three ultramafic nodules are texturally and isotopically distinct from the rest of the analyzed nodules. These are friable, have larger 87Sr/86Sr ratios, and may represent a deeper sampling of mantle rock than the granulite-facies nodules. They were, however, derived at a shallower depth than the alkalic magma. Thus they are not genetically related to either the magma or the granulite-facies nodules.

Much of the available analysis of policies for the disposal of publicly held resources is based on comparatively straightforward extensions of the neoclassical pricing and allocation theory. As such, these analyses have to a large extent not fully incorporated the fact that firms normally acquire rights to these resources in sealed tender markets. In this paper, a simple bidding model is used to show that the choice of disposal policies can influence the firm's bid and also the public revenues obtained from the sale of the resource. It is additionally shown that the implications of such policy choices are conditioned by the firm's attitudes towards risk. Finally, it is argued that a modification of existing prescriptions may be necessary if a more realistic specification of the disposal problem taking account of the sealed tender market in which rights are obtained, is considered.

The microwave emissivity of relatively low-loss media such as snow, ice, frozen ground, and lunar soil is strongly influenced by fine-scale layering and by internal scattering. Radiometric data, however, are commonly interpreted using a model of emission from a homogeneous, dielectric halfspace whose emissivity derives exclusively from dielectric properties. Conclusions based upon these simple interpretations can be erroneous. Examples are presented showing that the emission from fresh or hardpacked snow over either frozen or moist soil is governed dominantly by the size distribution of ice grains in the snowpack. Similarly, the thickness of seasonally frozen soil and the concentration of rock clasts in lunar soil noticeably affect, respectively, the emissivities of northern latitude soils in winter and of the lunar regolith. Petrophysical data accumulated in support of the geophysical interpretation of microwave data must include measurements of not only dielectric properties, but also of geometric factors such as finescale layering and size distributions of grains, inclusions, and voids.

Disposal of solid low-level wastes containing radionuclides by burial in shallow trenches was initiated during World War II at several sites as a method of protecting personnel from radiation and isolating the radionuclides from the hydrosphere and biosphere. Today, there are 11 principal shallow-land burial sites in the United States that contain a total of more than 1.4 million cubic meters of solid wastes contaminated with a wide variety of radionuclides. Criteria for burial sites have been few and generalized and have contained only minimal hydrogeologic considerations. Waste-management practices have included the burial of small quantities of long-lived radionuclides with large volumes of wastes contaminated with shorter-lived nuclides at the same site, thereby requiring an assurance of extremely long-time containment for the entire disposal site.

Studies at 4 of the 11 sites have documented the migration of radionuclides. Other sites are being studied for evidence of containment failure. Conditions at the 4 sites are summarized. In each documented instance of containment failure, ground water has probably been the medium of transport. Migrating radionuclides that have been identified include90Sr,137Cs,106Ru,239Pu,125Sb,60Co, and3H.

Shallow land burial of solid wastes containing radionuclides can be a viable practice only if a specific site satisfies adequate hydrogeologic criteria. Suggested hydrogeologic criteria and the types of hydrogeologic data necessary for an adequate evaluation of proposed burial sites are given. It is mandatory that a concomitant inventory and classification be made of the longevity, and the physical and chemical form of the waste nuclides to be buried, in order that the anticipated waste types can be matched to the containment capability of the proposed sites.

Ongoing field investigations at existing sites will provide data needed to improve containment at these sites and help develop hydrogeologic criteria for new sites. These studies have necessitated the development of special drilling, sampling, well construction, and testing techniques. A recent development in borehole geophysical techniques is downhole spectral gammaray analysis which not only locates but identifies specific radionuclides in the subsurface.

Field investigations are being supplemented by laboratory studies of the hydrochemistry of the transuranic elements, the kinetics of solid-liquid phase interactions, and the potential complexing of radionuclides with organic compounds and solvents which mobilize normally highly sorbable nuclides. Theoretical studies of digital predictive solute transport models are being implemented to assure their availability for application to problems and processes identified in the field and laboratory.

Landslides can cause seismic disturbances; landslides can also result from seismic disturbances, and earthquake-induced slides have caused loss of life in many countries. Slides can cause disastrous flooding, particularly when landslide dams across streams are breached, and flooding may trigger slides. Slope movement in general is a major process of the geologic environment that places constraints on engineering development. In order to understand and foresee both the causes and effects of slope movement, studies must be made on a regional scale, at individual sites, and in the laboratory.

Areal studies — some embracing entire countries — have shown that certain geologic conditions on slopes facilitate landsliding; these conditions include intensely sheared rocks; poorly consolidated, fine-grained clastic rocks; hard fractured rocks underlain by less resistant rocks; or loose accumulations of fine-grained surface debris.

Field investigations as well as mathematical- and physical-model studies are increasing our understanding of the mechanism of slope movement in fractured rock, and assist in arriving at practical solutions to landslide problems related to all kinds of land development for human use. Progressive failure of slopes has been studied in both soil and rock mechanics. New procedures have been developed to evaluate earthquake response of embankments and slopes. The finite element method of analysis is being extensively used in the calculation of slope stability in rock broken by joints, faults, and other discontinuities.

The relationship of this book to ornithology is so indirect that the work barely merits a review on these pages. In a rather subtle way, however, the book may have a considerable effect on at least one aspect of ornithology, that involving scientific collecting. In essence, the volume is an entry in the hunting versus antihunting controversy, by a historian who is a sportsman. A challenge to antihunting preservationists, the premise is that sportsmen (those who hunt and fish for pleasure rather than for food or profit), and not preservationists, were the founders of conservation concepts in the United States. The implied conclusion is that modern hunting and fishing are valid, conservation- oriented activities. The proof of the thesis depends on demonstrating that those persons who led the conservation movement were in fact sportsmen, as defined, rather than fitting any other categorization, and that only those who fit the definition were effective. The method is to detail both the sporting proclivities and conservation efforts of leaders in the movement and to ignore or belittle other activities of those persons and other persons not considered sportsmen. Although effective in making a point, the technique suffers from the difficulties inherent in any one-character classification.

The literature contains numerous studies on Red-winged Blackbird (Agelaius phoeniceus) reproduction. Francis (1971) summarized eight studies dealing with nesting success. These and other studies have also provided information on breeding chronology, clutch sizes, sex ratios, survival rates for eggs and nestlings, reproductive physiology, and other life history aspects of reproduction. With few exceptions, these studies have provided no data on the number of young fledged per female, per territorial male, or per unit area. This is especially true for upland nesting habitats where, at least in the midwestern United States, most Red-wings now nest (Graber and Graber 1963, Dyer et al. 1973). Also insufficient quantitative information is available on the extent and nature of renesting (i.e. nesting more than once in a nesting season) and on movements of adult females during the nesting season.

A better understanding of these aspects of reproduction is critical for the development of an accurate population-dynamics model for the species. Such a model is sorely needed to evaluate the impact and effectiveness of proposed population management strategies in places where blackbirds are deemed a health or safety hazard, or cause damage to agricultural crops (Tosh et al. 1970, Solman 1971, Stone et al. 1972).

This study had three objectives: (1) to determine the distribution, size, and number of Red-winged Blackbird territories for an old-field habitat; (2) to determine the number of nesting females, nesting success, extent of renesting, and number of young fledged for these territories; and (3) to examine movements of female Red-wings during the nesting season.

There was no significant difference between eggshell thicknesses of 1972-73 and pre-1946 collections. About 12% of the canvasbacks analyzed had elevated levels of blood lead with reduced ALAD enzyme activity. Adult canvasbacks collected from the Chesapeake Bay in 1975 had moderate to high levels of cadmium in their kidneys. Cadmium, in excessive amounts is very toxic and can curtail spermatogenesis in male birds.

Progress in understanding the behavior of trace elements during the processes that produce igneous rocks has been made possible by the parallel development of theoretical models to describe that behavior and analytical techniques that permit precise measurement of trace-element concentrations in igneous rocks and minerals. The result of this progress is that trace-element studies may now be used to place strong limits on both the degree of partial melting or fractional crystallization involved in the production of a given magma and the identity and quantity of the residual phases.

The Paloma Valley ring complex is one of the numerous plutons that make up the Cretaceous southern California batholith. The complex is composite, consisting of (1) an older, single ring dike and two subsidiary short-arced inner dikes, and (2) a younger set of thin short-arced dikes largely inside the older ring dike. The older ring dike, composed of granodiorite-quartz monzonite, has nearly vertical walls and is elliptical in plan; its long axis (14 km) is oriented west-northwest. It was emplaced in and contains numerous fragments of gabbro. The more than 200 short-arced granitic pegmatite dikes, mainly ranging from 0.2 to 1 m in thickness, define a domal ring dike set with moderately to steeply dipping outer dikes and nearly horizontal inner dikes. The younger dikes cut both the older ring dike and the gabbro. Spatially associated with the younger dikes are bodies of fine-grained granophyre that contain stringers of granitic pegmatite. The granophyre has an Mg content similar to that of the younger ring-dike rock, but contains less K and more Fe. The older ring dike is interpreted to have been magmatically emplaced in an elliptical zone of ring fracturing in gabbro; the magma made room by stoping the denser gabbro with little assimilation. Upon a release of pressure, a set of domal fractures formed, along which volatile-rich magma was emplaced, forming the younger ring dikes. Granophyre resulted from pressure-quenching through a loss of volatiles. Residual volatiles, or volatiles that were introduced later, recrystallized parts of the granophyre and caused the formation of pegmatite stringers.

Analyses of oxygen isotopes in whole-rock samples of 58 Precambrian and Phanerozoic trondhjemites and siliceous gneisses and of 28 cogenetic mafic to intermediate rocks from North America, Fennoscandia, and southern Africa give the following results:

1. (1) 47 trondhjemites, tonalites, and mostly Archean acidic gneisses that apparently are not isotopically disturbed show an overage δ 15O+7.3‰\">+7.3‰ and a range of 5.2–8.9‰; 11 other samples are slightly to moderately disturbed and show higher values; and

2. (2) the mafic rocks show a wide range of δ-values, from about 0–9‰ but the undisturbed ones give an average δ 18O of 5.2‰\">5.2‰.

The δ 18O values of the trondhjemitic intrusives and siliceous gneisses of similar composition are lower than those of most granitic rocks and support models for derivation of these rocks from basaltic parents. This approach, however, cannot be used to determine if individual bodies formed by differentiation or by partial melting.
