Limestone, dolomite, and argillaceous rocks were of particular interest because these have spectral reflectance features that might make them difficult to separate from some of the altered rocks when these images are used.The laboratory and field evaluation of a color ratio composite image, supported by in situ spectral reflectance measurements and an alteration map compiled from a published map, shows that silicified, argillized, and pyritized rocks can be mapped in detail utilizing an intense OH absorption band centered near 2.2 mu m. This absorption band is absent or weak in most of the unaltered rocks. However, the 2.2-mu m band is also weak in the reflectance spectra representing the other three types of altered rocks--hydrothermal dolomite, calcitic volcanic rocks, and chloritized rocks. Consequently, these altered rocks are not consistently distinguished from unaltered rocks in these images. Furthermore, very pure dolomite spectra have an intense 2.33- mu m CO (super -3) absorption band that is not distinguishable from the 2.2-mu m band in these images; therefore, the pure dolomite exposures were distinguished from the silicified, argillized, and pyritized rocks through field checking. The 2.33-mu m absorption feature is weak in spectra for less pure carbonate rocks. Separation of these altered rocks and local exposures of argillaceous rocks also posed problems because of their mineralogic and hence spectral reflectance similarities.These results are especially important for estimating the potential of the 1.6- and 2.2-mu m bands in the Landsat D thematic mapper for mapping altered rocks. Here, as we found in an earlier study in south-central Nevada, limonite-poor hydrothermally altered rocks that were not consistently distinguished in Landsat multispectral scanner images should be detectable using these two thematic mapper bands in combination with other bands at shorter wave-lengths. However, distinguishing among some hydrothermally altered and unaltered rocks will require other approaches, including analysis of high-spectral resolution measurements in the 2.0- and 2.5-mu m region and multispectral thermal infrared data.</span></p>","language":"English","publisher":"Society of Economic Geologists","doi":"10.2113/gsecongeo.77.2.441","issn":"03610128","usgsCitation":"Rowan, L.C., and Kahle, A., 1982, Evaluation of 0.46- to 2.36-mu m multispectral scanner images of the east Tintic mining district, Utah, for mapping hydrothermally altered rocks: Economic Geology, v. 77, no. 2, p. 441-452, https://doi.org/10.2113/gsecongeo.77.2.441.","productDescription":"12 p.","startPage":"441","endPage":"452","numberOfPages":"12","costCenters":[],"links":[{"id":221187,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"77","issue":"2","noUsgsAuthors":false,"publicationDate":"1982-04-01","publicationStatus":"PW","scienceBaseUri":"505a0c0ae4b0c8380cd529ec","contributors":{"authors":[{"text":"Rowan, L.

Proximal graded sand beds on the delta-front platform near the shoreline are coarser (2-3phi ), thicker (10 to 20 cm), and contain more complete vertical sequences of sedimentary structures than distal beds. The inshore graded vertical sequence of structures from the base to the top of individual sand layers includes plane-parallel lamination (S<span>&nbsp;</span><sub>b</sub><span>&nbsp;</span>), cross lamination (S<span>&nbsp;</span><sub>c</sub><span>&nbsp;</span>), plane-parallel lamination (S<span>&nbsp;</span><sub>d</sub><span>&nbsp;</span>), and mud (S<span>&nbsp;</span><sub>e</sub><span>&nbsp;</span>) analogous to the Bouma T (sub a-e) turbidite sequence. Structures vary between interchannel platform deposits with complete S<span>&nbsp;</span><sub>b</sub><span>&nbsp;</span>-S<span>&nbsp;</span><sub>e</sub><span>&nbsp;</span>sequences and channel-floor sands that are all trough cross-laminated. Distally, storm-sand layers change to thin (1 to 5 cm) silt beds that contain flat and ripple-drift lamination (S (sub c-e,de) ), are commonly bioturbated, and are associated with shell and pebble lags from storm-wave reworking. The sequence of graded sands appears to be related to the major storm surges that occur every several years. The major storms increase the average 10-m water depth in southern Norton Sound as much as 5 m and cause fluctuations in pore pressure from wave cyclic loading that may liquefy the upper 2 to 3 m of sediment. Storm-associated bottom currents, possibly dominated by rapidly waning ebb flow, transport the liquefied inshore sand far offshore (&gt; 100 kin). Such shallow-water graded layers off lobate deltas may be distinguished from similar deep-water turbidites by: 1) the predominance of trough cross-lamination, perhaps resulting from wave oscillation effects, in the proximal part of the system, and 2) gradation to common shallow marine fossils, bioturbation, and storm lag layers in distal areas.</p></div></div>","language":"English","publisher":"SEPM","doi":"10.1306/212F7F9A-2B24-11D7-8648000102C1865D","issn":"00224472","usgsCitation":"Nelson, C., 1982, Modern shallow-water graded sand layers from storm surges, Bering Shelf: a mimic of Bouma sequences and turbidite systems: Journal of Sedimentary Petrology, v. 52, no. 2, p. 537-545, https://doi.org/10.1306/212F7F9A-2B24-11D7-8648000102C1865D.","productDescription":"9 p.","startPage":"537","endPage":"545","numberOfPages":"9","costCenters":[],"links":[{"id":221188,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"52","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5ca1e4b0c8380cd6fe37","contributors":{"authors":[{"text":"Nelson, C.H.","contributorId":88346,"corporation":false,"usgs":true,"family":"Nelson","given":"C.H.","email":"","affiliations":[],"preferred":false,"id":361582,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The functioning of most parts of this system was illustrated by activity during 1971 and 1972. When a 29-month-long eruption at Mauna Ulu on the east rift zone began to wane in 1971, the summit region of the volcano began to inflate rapidly; apparently, blockage of the feeder conduit to Mauna Ulu diverted a continuing supply of mantle-derived magma to prolonged storage in the summit reservoir. Rapid inflation of the summit area persisted at a nearly constant rate from June 1971 to February 1972, when a conduit to Mauna Ulu was reopened. The cadence of inflation was twice interrupted briefly, first by a 10-hour eruption in Kilauea Caldera on 14 August, and later by an eruption that began in the caldera and migrated 12 km down the southwest rift zone between 24 and 29 September. The 14 August and 24-29 September eruptions added about 107 m3 and 8 ?? 106 m3, respectively, of new lava to the surface of Kilauea. These volumes, combined with the volume increase represented by inflation of the volcanic edifice itself, account for an approximately 6 ?? 106 m3/month rate of growth between June 1971 and January 1972, essentially the same rate at which mantle-derived magma was supplied to Kilauea between 1952 and the end of the Mauna Ulu eruption in 1971. The August and September 1971 lavas are tholeiitic basalts of similar major-element chemical composition. The compositions can be reproduced by mixing various proportions of chemically distinct variants of lava that erupted during the preceding activity at Mauna Ulu. Thus, part of the magma rising from the mantle to feed the Mauna Ulu eruption may have been stored within the summit reservoir from 4 to 20 months before it was erupted in the summit caldera and along the southwest rift zone in August and September. The September 1971 activity was only the fourth eruption on the southwest rift zone during Kilauea's 200 years of recorded history, in contrast to more than 20 eruptions on the east rift zone. Order-of-magnitude differences in topographic and geophysical expression indicate greatly disparate eruption rates for far more than historic time and thus suggest a considerably larger dike swarm within the east rift zone than within the southwest rift zone. Characteristics of the historic eruptions on the southwest rift zone suggest that magma may be fed directly from active lava lakes in Kilauea Caldera or from shallow cupolas at the top of the summit magma reservoir, through fissures that propagate down rift from the caldera itself at the onset of eruption. Moreover, emplacement of this magma into the southwest rift zone may be possible only when compressive stress across the rift is reduced by some unknown critical amount owing either to seaward displacement of the terrane south-southeast of the rift zone or to a deflated condition of Mauna Loa Volcano adjacent to the northwest, or both. The former condition arises when the forceful emplacement of dikes into the east rift zone wedges the south flank of Kilauea seaward. Such controls on the potential for eruption along the southwest rift zone may be related to the topographic and geophysical constrasts between the two rift zones. ?? 1982.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Volcanology and Geothermal Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"03770273","usgsCitation":"Duffield, W.A., Christiansen, R., Koyanagi, R.Y., and Peterson, D.W., 1982, Storage, migration, and eruption of magma at Kilauea volcano, Hawaii, 1971-1972: Journal of Volcanology and Geothermal Research, v. 13, no. 3-4, p. 273-307.","startPage":"273","endPage":"307","numberOfPages":"35","costCenters":[],"links":[{"id":220720,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"13","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9874e4b08c986b31c045","contributors":{"authors":[{"text":"Duffield, W.

Trace amounts of tourmaline occur associated with volcanic-hosted deposits in the Piedmont and New England and also in the Trondheim district. Tourmaline associated with the massive sulphide deposits are Mg- rich dravites with major- and trace-element compositions significantly different from schorl. It is suggested that the necessary B was produced by submarine exhalative processes as a part of the same hydrothermal system that deposited the ores.

On the basis of chemical character, as defined by a trilinear plot of per cent milliequivalents, and light-stable isotope data, the waters in the geothermal area can be divided into waters that have and have not mixed with cold water. The non-mixed waters have essentially a constant value of light-stable isotopes but show a large variation in chloride content. The variation of chloride composition is not the usual pattern for deep geothermal waters, where it is normally assumed that the deep water has a single chloride composition. Different mixed waters also have hot-water sources of varying chloride composition. Plots of chloride values on cross-sections show that water circulation patterns are confused, with non-mixed waters having different chloride concentrations located in close proximity. Three models can explain the characteristics of the deep geothermal water: (1) in addition to near-surface mixing of cold and hot water, there is deep mixing of two hot waters with the same enthalpy and isotopic composition but differing chloride concentrations to produce the range of chloride concentrations found in the deep geothermal water; (2) there is a single deep hot water, and the range of chloride concentrations is produced by the water passing through a zone of highly soluble materials (most likely in the sedimentary section above the basement) in which waters have different residence times or slightly different circulation paths; (3) the varying chloride concentrations in space have been caused by varying chloride concentrations in the deep feed water through time. Some of this older water has not been flushed from the system by the natural discharge. Although one model may seem more plausible than the others, the available data do not rule out any of them. Data for water samples from the Raft River and Jim Sage Mountains show that water from these areas is probably the source for the cold mixing water determined from end-members on mixing lines. Data for water samples in the Upper Raft River Valley show that the thermal anomaly found at Almo 1 is probably not related to the Raft River geothermal area. The water is different in type as shown by its placement on a trilinear plot, and the isotopes are different enough to show that it is probably a different water. Isotopic compositions of samples from a wide area around the Raft River geothermal system indicate that the likely source of the recharge water is the southern Albion Mountains and western Raft River Mountains. The recharge area is at one end of the Narrows zone, and the geothermal area is along the Narrows zone; thus it is likely that the Narrows zone defines the circulation path.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/0375-6505(82)90030-X","issn":"03756505","usgsCitation":"Nathenson, M., Nehring, N., Crosthwaite, E., Harmon, R., Janik, C., and Borthwick, J., 1982, Chemical and light-stable isotope characteristics of waters from the Raft River geothermal area and environs, Cassia County, Idaho; Box Elder County, Utah: Geothermics, v. 11, no. 4, p. 215-237, https://doi.org/10.1016/0375-6505(82)90030-X.","productDescription":"23 p.","startPage":"215","endPage":"237","numberOfPages":"23","costCenters":[],"links":[{"id":221117,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"11","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f547e4b0c8380cd4c157","contributors":{"authors":[{"text":"Nathenson, M.","contributorId":46632,"corporation":false,"usgs":true,"family":"Nathenson","given":"M.","email":"","affiliations":[],"preferred":false,"id":361260,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nehring, N.L.","contributorId":21157,"corporation":false,"usgs":true,"family":"Nehring","given":"N.L.","email":"","affiliations":[],"preferred":false,"id":361259,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Crosthwaite, E.

For most rocks, water diffuses more rapidly than heat, assuring that groundwater is not heated along a constant-volume pressure path and that thermal expansion and pressurization adjacent to the intrusion drives a flow that extends well beyond the heated region. The forcing parameter for pressurization and flow is α Δ</span><i>T</i><span>, where α is a thermal expansion coefficient reflecting the overall expansion of water heated through the temperature difference Δ</span><i>T</i><span>&nbsp;between the initial ambient and intrusive values. Pore pressure increases due to heating are greatest when the intrusion is emplaced rapidly and where the intrusive contact is impervious to groundwater contained in stiff, impermeable rocks with high thermal diffusivities and porosities. The maximum velocity of water flowing in pores decays with the inverse square root of time and is insensitive to hydraulic properties of the host rocks. Pressures are lessened and flow directions are reversed with the onset of hydrothermal convection. This occurs at times ranging from hours to weeks after onset of intrusion. As magma rises into near-surface rocks, steam can be generated. Solutions indicate that pressure increases and velocities are sensitive to the overall amount of expansion rather than the behavior of the water-steam transition. Both the overall thermal expansion coefficient α and the temperature difference Δ</span><i>T</i><span>&nbsp;are greater in shallow (&lt;1 km) environments than in deep (∼5 km) ones. Thus, for rocks with similar transport properties, pressure increases due to heating are greatest in shallow environments. Although solutions can be applied to rocks with a wide variety of properties, pressure increases are calculated for compliant quartz-rich sedimentary rocks with a porosities between 1 and 20% and permeabilities between 1 darcy and 1 μdarcy, subject to temperature increases of 500 and 1000 K at depths ranging from 0.1 to 5 km in a region of hydrostatic pressures and normal geothermal gradient. Such rocks, with porosities greater than 5%, permeabilities less than a 0.1 mdarcy, and drained hydrostatic compressibilities of 10</span><sup>−4</sup><span>/MPa, undergo pressure increases greater than 10 MPa (100 bars)for conditions typical of water table depths of 2.5 km and heating to 500 K above ambient. Similar rocks, but with permeabilities less than 1 mdarcy, undergo pressure increases of 10 MPa for conditions typical of 1 km water table depth. Rocks commonly considered to be good aquifers undergo pressure increases of less than 1 MPa, primarily because of their high permeability. Although these estimates neglect the effects of fracturing and brecciation that may accompany such pressure increases, calculations indicate that pressure increases due to heating of cool groundwater can lead to failure of host rocks by a phreatic mechanism.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB087iB09p07739","issn":"01480227","usgsCitation":"Delaney, P., 1982, Rapid intrusion of magma into wet rock: Groundwater flow due to pore pressure increases: Journal of Geophysical Research Solid Earth, v. 87, no.

Reference hypocenters for this special data set are determined for shallow earthquakes from local-network data and for deep earthquakes from combined local and teleseismic data by joint inversion for structure and location. The high-velocity lithospheric slab beneath the central Aleutians may displace hypocenters that are located using spherically symmetric Earth models; the amount of displacement depends on the position of the earthquakes with respect to the slab and on whether local or teleseismic data are used to locate the earthquakes. Hypocenters for trench and intermediate-depth events appear to be minimally biased by the effects of slab structure on rays to teleseismic stations. However, locations of intermediate-depth events based on only local data are systematically displaced southwards, the magnitude of the displacement being proportional to depth. Shallow-focus events along the main thrust zone, although well located using only local-network data, are severely shifted northwards and deeper, with displacements as large as 50 km, by slab effects on teleseismic travel times. Hypocenters determined by a method that utilizes seismic ray tracing through a three-dimensional velocity model of the subduction zone, derived by thermal modeling, are compared to results obtained by the method of joint hypocenter determination (JHD) that formally assumes a laterally homogeneous velocity model over the source region and treats all raypath anomalies as constant station corrections to the travel-time curve. The ray-tracing method has the theoretical advantage that it accounts for variations in travel-time anomalies within a group of events distributed over a sizable region of a dipping, high-velocity lithospheric slab. In application, JHD has the practical advantage that it does not require the specification of a theoretical velocity model for the slab. Considering earthquakes within a 260 km long by 60 km wide section of the Aleutian main thrust zone, our results suggest that the theoretical velocity structure of the slab is presently not sufficiently well known that accurate locations can be obtained independently of locally recorded data. Using a locally recorded earthquake as a calibration event, JHD gave excellent results over the entire section of the main thrust zone here studied, without showing a strong effect that might be attributed to spatially varying source-station anomalies. We also calibrated the ray-tracing method using locally recorded data and obtained results generally similar to those obtained by JHD. ?? 1982.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Physics of the Earth and Planetary Interiors","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/0031-9201(82)90099-1","issn":"00319201","usgsCitation":"Engdahl, E., Dewey, J.W., and Fujita, K., 1982, Earthquake location in island arcs: Physics of the Earth and Planetary Interiors, v. 30, no. 2-3, p. 145-156, https://doi.org/10.1016/0031-9201(82)90099-1.","startPage":"145","endPage":"156","numberOfPages":"12","costCenters":[],"links":[{"id":220711,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":267343,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0031-9201(82)90099-1"}],"volume":"30","issue":"2-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a04f7e4b0c8380cd50bbc","contributors":{"authors":[{"text":"Engdahl, E.R.","contributorId":22906,"corporation":false,"usgs":true,"family":"Engdahl","given":"E.R.","email":"","affiliations":[],"preferred":false,"id":361345,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dewey, J.

The relative depth and time of siderite precipitation can be inferred from the structure, mineralogy and isotopic composition of these concretions. Concretions that formed at shallow depths, early in the history of the sediment, contain a high percentage (75-85%) of carbonate, preserve uncompacted structures and have oxygen isotopic ratios similar to that of sea-water. In contrast, concretions that formed later and/or at greater depths have lower carbonate content and lower 18O/16O ratios. Concretions in rapidly deposited sediments formed at shallow depths (<10 m), and those in sediments that accumulated slowly formed at greater depths. These differences agree with the fossil evidence. Siderite did not form until nearly all the dissolved sulphur had been reduced and precipitated as pyrite; the excess organic matter produced methane at about the same time.-H.R.B.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Sedimentary Petrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00224472","usgsCitation":"Gautier, D.L., 1982, Siderite concretions: indicators of early diagenesis in the Gammon shale (Cretaceous).: Journal of Sedimentary Petrology, v. 52, no. 3, p. 859-871.","startPage":"859","endPage":"871","numberOfPages":"13","costCenters":[],"links":[{"id":221127,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"52","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8ef2e4b08c986b318c3e","contributors":{"authors":[{"text":"Gautier, D.
