The Bishop Tuff represents a single eruption of chemically zoned rhyolitic magma. Six whole rock samples spanning the compositional and temperature range yield initial87Sr/86Sr of 0.7060–0.7092 andδ18O of 5.9–10.3‰. Six constituent sanidines yield smaller ranges of initial87Sr/86Sr of 0.7061–0.7069 andδ18O of 6.7–7.9. In contrast143Nd/144Nd ratios for the six whole rocks and two constituent magnetites exhibit negligible variation with a mean of0.51258 ± 1. These data are used to show that the phenocrysts were precipitated from an already chemically zoned liquid, that the zoning process involved negligible assimilation of, or exchange with, country rocks and that the extreme Sr and O isotopic disequilibria are probably the result of post-eruptive interaction with meteoric water. The parent magma hadɛNd = −0.9, ɛSr = +23 andδ18O = 7‰ and was formed from mantle-derived magmas and/or melts of lower crustal rocks isotopically similar to parts of the Sierra Nevada Batholith.
The D/H ratios and water contents in fresh submarine basalts from the Mid-Atlantic Ridge, the East Pacific Rise, and Hawaii indicate that the primary D/H ratios of many submarine lavas have been altered by processes including (1) outgassing, (2) addition of seawater at magmatic temperature, and (3) low-temperature hydration of glass. Decreases in δD and H2O+ from exteriors to interiors of pillows are explained by outgassing of water whereas inverse relations between δD and H2O+ in basalts from the Galapagos Rise and the FAMOUS Area are attributed to outgassing of CH4 and H2. A good correlation between δD values and H2O is observed in a suite of submarine tholeiites dredged from the Kilauea East Rift Zone where seawater (added directly to the magma), affected only the isotopic compositions of hydrogen and argon. Analyses of some glassy rims indicate that the outer millimeter of the glass can undergo lowtemperature hydration by hydroxyl groups having δD values as low as −100.
δD values vary with H2O contents of subaerial transitional basalts from Molokai, Hawaii, and subaerial alkali basalts from the Society Islands, indicating that the primary δD values were similar to those of submarine lavas.
Extrapolations to possible unaltered δD values and H2O contents indicate that the primary δD values of most thoteiite and alkali basalts are near −80 ± 5: the weight percentages of water are variable, 0.15–0.35 for MOR tholeiites, about 0.25 for Hawaiian tholeiites, and up to 1.1 for alkali basalts. The primary δD values of −80 for most basalts are comparable to those measured for deep-seated phlogopites. These results indicate that hydrogen, in marked contrast to other elements such as Sr, Nd, Pb, and O, has a uniform isotopic composition in the mantle. This uniformity is best explained by the presence of a homogeneous reservoir of hydrogen that has existed in the mantle since the very early history of the Earth.

A strong positive correlation has been found between formation-water salinity and Ra activity, resulting from the interaction of formation water with aquifer matrix. Ra isotopes enter the fluid phase after being produced by the decay of parent elements U and Th, which are located at sites on and within the solid matrix. Processes that are belived to be primarily responsible for transferring Ra from matrix to formation water are chemical leaching and alpha-particle recoil. Factors controlling the observed salinity-Ra relationship may be one or a combination of the following factors: (a) ion exchange; (b) increased solubility of matrix silica surrounding Ra atoms, coupled with a salinity-controlled rate of reequilibration of silica between solution and quartz grains; and (c) the equilibration of Ra in solution with detrial barite within the aquifer. No difference was found in the brine-Ra relation in water produced from oil or gas wells and water produced from wells penetrating only water-bearing aquifers, although the relation was more highly correlated for water-bearing aquifers than hydrocarbon-containing reservoirs. ?? 1984.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Chemical Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/0009-2541(84)90186-4","issn":"00092541","usgsCitation":"Kraemer, T.F., and Reid, D., 1984, The occurrence and behavior of radium in saline formation water of the U.S. Gulf Coast region: Chemical Geology, v. 46, no. 2, p. 153-174, https://doi.org/10.1016/0009-2541(84)90186-4.","startPage":"153","endPage":"174","numberOfPages":"22","costCenters":[],"links":[{"id":266106,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0009-2541(84)90186-4"},{"id":219659,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"46","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bae31e4b08c986b323f48","contributors":{"authors":[{"text":"Kraemer, T.

The tube wall profile was made by direct observation with a recording optical pyrometer. The sodium line reversal method was used to establish the heating rate of the furnace atmosphere, and appearance temperatures for a series metals of differing volatility was used to establish platform profiles. The tube wall heating rate was nearly linear at 2240°C s− until the desired temperature was reached after which the temperature remained constant. The furnace atmosphere reached a given temperature 0.2–0.4 s later than the tube wall through most of the atomize cycle. The platform lagged the tube wall 0.5–0.8 s. Under typical operating conditions the furnace atmosphere was 100–200°C cooler than the tube wall and at nearly constant temperature when the analyte vaporized from the platform. The L'vov platform causes the cyclically heated commercial furnace to approximate the behavior of a constant temperature furnace during atomization.

Progradation, lateral shifting, and abandonment of these complexes created four major landward-thinning tongues of the upper sandstone bed of the Star Point Sandstone that extend into the lowermost Blackhawk Formation. Each tongue of the Star Point Sandstone trends northwest to southeast, subparallel to the general orientation of the Late Cretaceous paleoshoreline, and represents accretion-ridge, distributary-channel, and mouth-bar sandstones. The accretion-ridge or barrier-island sandstones grade landward into coastwise lagoonal and back-barrier swamp deposits, which, in turn, merge with bayhead deposits of short-headed streams. These deposits grade laterally into delta-plain deposits that consist of major distributary channels which crosscut the coastwise lagoons. Two coal populations were formed in this paleogeographic setting: delta-plain and back-barrier coals. Delta-plain coals formed as thin to thick, discontinuous bodies. Back-barrier coals are thicker and more laterally continuous. They parallel depositional strike and accumulated in swamps on surfaces of infilled lagoons. Here, the swamps were sites of accumulation of thick coals and were influenced by abandonment of associated deltaic barrier-island complexes. Successive offlap events resulted in accumulation of the Hiawatha coal, not as a single continuous bed, but as a series of discontinuous, related coal bodies.
Postfire regeneration of the shrub and herb vegetation on eight coastal slopes of California coastal sage scrub was studied in the first two growing seasons after fire. All shrub species resprouted with the exception of the suffrutescent Lotus scoparius, though it is not known if this species was alive prior to the fire. It was estimated that 70% of the prefire shrub populations resprouted and these sprouts covered one third of the ground surface by the end of the second season. In contrast to chaparral, seedling establishment from soil-stored seed was low (∼ 102-103/ha) in the 1st postfire year. Resprouts of most major species (Artemisia californica, Encelia californica, Haplopappus squarrosus, Eriogonum cinereum) flowered and set seed in the 1st year. Seedling densities were ∼ 104-106/ha in the 2nd year. Herbs dominated the first postfire season vegetation in number of species, cover and biomass. The magnitude of the postfire herb flora was comparable to that in chaparral after fire and included many of the same species. On several slopes, \"pyrophyte endemic\" annuals (Lupinus succulentus, Lotus salsuginosus, Phacelia parryi) dominated the first season and were rare or absent in the 2nd year. One major distinction between these coastal sage sites and chaparral was that resprouting perennial herbs dominated some slopes in the first postfire season and most slopes in the second season in coastal sage. Seedling recruitment of perennial herbs was rare; 26 of the 28 species were present only as resprouts. Total herb cover was markedly lower in the 2nd year despite the fact that it was a wetter year. Between the 1st and 2nd years, shrub cover ∼ doubled, largely from resprouts, annual herb cover declined markedly and perennial herb cover remained relatively constant. The perennial bunchgrass Stipa lepida was an important component of the herb flora on all slopes and was the only species (herb or shrub) to exceed 1/m2 on all eight slopes.

Two Ge(HP) gamma-ray detectors were used: one in a borehole sonde, and one at the outside wall of the sample tank opposite the neutron generator target. Gamma-ray spectra were collected by the outside detector during each of 10 discrete time windows during the 10 ms period following the onset of gamma-ray build-up after each neutron burst. The sample was measured first when dry and then when saturated with water. In the dry sample, gamma rays due to inelastic neutron scattering, neutron capture, and decay were counted during the first (150 ??s) time window. Subsequently only capture and decay gamma rays were observed. In the wet sample, only neutron capture and decay gamma rays were observed. Neutron capture gamma rays dominated the spectrum during the period from 150 to 400 ??s after the neutron burst in both samples, but decreased with time much more rapidly in the wet sample. A signal-to-noise-ratio (S/N) analysis indicates that optimum conditions for neutron capture analysis occurred in the 350-800 ??s window. A poor S/N in the first 100-150 ??s is due to a large background continuum during the first time interval. Time gating can be used to enhance gamma-ray spectra, depending on the nuclides in the target material and the reactions needed to produce them, and should improve the sensitivity of in situ well logging. ?? 1984.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Nuclear Instruments and Methods In Physics Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/0167-5087(84)90159-5","issn":"01675087","usgsCitation":"Evans, L., Trombka, J., Jensen, D., Stephenson, W., Hoover, R.A., Mikesell, J., Tanner, A., and Senftle, F.E., 1984, Inter-pulse high-resolution gamma-ray spectra using a 14 MeV pulsed neutron generator: Nuclear Instruments and Methods In Physics Research, v. 219, no. 1, p. 233-242, https://doi.org/10.1016/0167-5087(84)90159-5.","startPage":"233","endPage":"242","numberOfPages":"10","costCenters":[],"links":[{"id":219442,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":268838,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0167-5087(84)90159-5"}],"volume":"219","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3ca3e4b0c8380cd62ee0","contributors":{"authors":[{"text":"Evans, L.G.","contributorId":107426,"corporation":false,"usgs":true,"family":"Evans","given":"L.G.","email":"","affiliations":[],"preferred":false,"id":358583,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Trombka, J.I.","contributorId":8985,"corporation":false,"usgs":true,"family":"Trombka","given":"J.I.","email":"","affiliations":[],"preferred":false,"id":358576,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Jensen, D.H.","contributorId":46684,"corporation":false,"usgs":true,"family":"Jensen","given":"D.H.","email":"","affiliations":[],"preferred":false,"id":358579,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Stephenson, W.A.","contributorId":76462,"corporation":false,"usgs":true,"family":"Stephenson","given":"W.A.","email":"","affiliations":[],"preferred":false,"id":358582,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Hoover, R.

By late April 1982 a lake had begun to form on the crater floor, and by November 1982 it attained a maximum surface area of 1.4 × 105 m2 and a volume of 5 × 106 m3. Accumulation of 4–5 m of rainfall between July and October 1982 largely formed the lake. In January 1983, temperatures of fumaroles on the crater floor and lower crater walls ranged from 98 to 115°C; by October 1983 the maximum temperature of fumarole emissions was 99°C. In January 1983 fumarole gas emissions were greater than 99 vol. % H2O with traces of CO2, SO2, and H2S. The water of the lake was a hot (T = 52–58°C), acidic (pH = 0.5), dilute solution (34,046 mg L−1 dissolved solids; Cl/S = 20.5). Sediment from the lake contains the same silicate minerals as the rocks of the 1982 pyroclastic deposits, together with less than 1% of elemental sulfur. The composition and temperature of the lake water is attributed to: (1) solution of fumarole emissions; (2) reaction of lake water with hot rocks beneath the lake level; (3) sediments washed into the lake from the crater walls; (4) hydrothermal fluids leaching sediments and formational waters in sedimentary rocks of the basement; (5) evaporation; and (6) precipitation.

Documented penetration by the SIR-A signal of dry surficial sediment to depths of a meter or more revealed bedrock geologic features and networks of former stream valleys otherwise concealed beneath windblown sand, alluvium, and colluvial deposits. 'Radar units' mapped on SIR-A images according to relative brightness and degree of mottling correspond to subsurface geologic and topographic features identified in more than 50 test pits. Petrologic examination of pit samples confirms that a variety of depositional environments existed in this now hyper-arid region before it was mantled by windblown sand sheets and dunes. Wet sand was discovered in two buried valleys shown on the radar images and located in the field with the aid of co-registered maps and Landsat images, and a satellite navigation device. Buried valleys whose streams once traversed mineralized zones are potential sites of placers (gold, tin).","conferenceTitle":"Proceedings of the International Symposium on Remote Sensing of Environment, Third Thematic Conference: Remote Sensing for Exploration Geology.","conferenceLocation":"Colorado Springs, CO, USA","language":"English","publisher":"Environmental Research Inst of Michigan","publisherLocation":"Ann Arbor, MI, USA","usgsCitation":"Breed, C.S., McCauley, J., and Schaber, G.G., 1984, SHUTTLE IMAGING RADAR PROVIDES FRAMEWORK FOR SUBSURFACE GEOLOGIC EXPLORATION IN EGYPT AND SUDAN., Proceedings of the International Symposium on Remote Sensing of Environment, Third Thematic Conference: Remote Sensing for Exploration Geology., Colorado Springs, CO, USA.","startPage":"949","costCenters":[],"links":[{"id":219916,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aaf4ce4b0c8380cd874eb","contributors":{"authors":[{"text":"Breed, Carol S.","contributorId":100904,"corporation":false,"usgs":true,"family":"Breed","given":"Carol","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":365957,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McCauley, John F.","contributorId":54973,"corporation":false,"usgs":true,"family":"McCauley","given":"John F.","affiliations":[],"preferred":false,"id":365956,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schaber, Gerald G.","contributorId":12511,"corporation":false,"usgs":true,"family":"Schaber","given":"Gerald","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":365955,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":1007787,"text":"1007787 - 1984 - Intertidal community structure in central and southern California: the interaction between human disturbance, bird predation and limpet territoriality","interactions":[],"lastModifiedDate":"2012-02-02T00:04:19","indexId":"1007787","displayToPublicDate":"1984-01-01T00:00:00","publicationYear":"1984","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":735,"text":"American Malacological Bulletin","active":true,"publicationSubtype":{"id":10}},"title":"Intertidal community structure in central and southern California: the interaction between human disturbance, bird predation and limpet territoriality","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"American Malacological Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Lindberg, D.R., Estes, J.A., and Warheit, K., 1984, Intertidal community structure in central and southern California: the interaction between human disturbance, bird predation and limpet territoriality: American Malacological Bulletin, v. 2.","productDescription":"p. 80","startPage":"80","numberOfPages":"80","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":129890,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49d8e4b07f02db5df559","contributors":{"authors":[{"text":"Lindberg, D.

Data were collected for about 300 runoff events on four different urban land-use basins - commercial, highway, single-family residential, and apartment. These data were collected from sewers that carried only stormwater runoff. In analyzing the rainfall-runoff data, three types of relations were found. A one-curve, linear relation occurred for the commercial basin that has 98 percent of the basin as hydraulically effective impervious area. A two-curve, intercepted relation occurred for the highway basin - a linear curve for the low and medium events observed and a second-degree curve for high events observed. A two-curve, disjointed relation occurred for the remaining two basins - the residential basin and the apartment basin. This relation also contained a linear curve for low and medium events and a second-degree curve for the high events. However, the two curves do not intersect, but are disjointed.","largerWorkTitle":"University of Kentucky, Office of Engineering Services, (Bulletin) UKY BU","conferenceTitle":"Proceedings - 1984 International Symposium on Urban Hydrology, Hydraulics and Sediment Control.","conferenceLocation":"Lexington, KY, USA","language":"English","publisher":"Univ of Kentucky","publisherLocation":"Coll of Engineering, Lexington, KY, USA","issn":"02706504","isbn":"089779606X","usgsCitation":"Miller, R.A., 1984, RAINFALL-RUNOFF MECHANICS FOR DEVELOPED URBAN BASINS, SOUTH FLORIDA., in University of Kentucky, Office of Engineering Services, (Bulletin) UKY BU, Lexington, KY, USA, p. 135-141.","startPage":"135","endPage":"141","numberOfPages":"7","costCenters":[],"links":[{"id":221970,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a9323e4b0c8380cd80c35","contributors":{"authors":[{"text":"Miller, Robert A.","contributorId":52938,"corporation":false,"usgs":true,"family":"Miller","given":"Robert","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":364493,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ]}
