Calculated source compositions range from lherzolite to olivine websterite. Nonmodal melting of small amounts of ilmenite (≤3%) in the sources seems to be required by the Lu/Hf data. A comparison of the Hf and Nd isotopic characteristics between the mare basalts and terrestrial oceanic basalts reveals that the εHf/εNd ratios in low-Ti mare basalts are much higher than in terrestrial oceanic basalts. The results are qualitatively consistent with the hypothesis that terrestrial basalt sources are partial melt residues whereas mare basalt sources are cumulates. Alternatively, the results may imply that the terrestrial mantle has evolved in two (or more) stages of evolution, and that the net effect was depletion of the mantle during the first ∼1–3 b.y. followed by enrichment during the last 1–2 b.y.; or simply that there is a difference in Lu-Hf crystal-liquid partitioning (relative to Sm-Nd between the lunar and terrestrial mantles.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB089iS02p0B459","issn":"00221406","isbn":"0875902332","usgsCitation":"Unruh, D., Stille, P., Patchett, P., and Tatsumoto, M., 1984, Lu-Hf and Sm-Nd evolution in lunar mare basalts: Journal of Geophysical Research Solid Earth, v. 89, no.

All shrub species resprouted with the exception of the suffrutescent <i>Lotus scoparius</i>, 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 (<i>Artemisia californica</i>, <i>Encelia californica</i>, <i>Haplopappus squarrosus</i>, <i>Eriogonum cinereum</i>) 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 (<i>Lupinus succulentus</i>, <i>Lotus salsuginosus</i>, <i>Phacelia parryi</i>) 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 <i>Stipa lepida</i> 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.</span></p>","language":"English","publisher":"University of Notre Dame","doi":"10.2307/2425548","usgsCitation":"Keeley, J.E., and Keeley, S.C., 1984, Post-fire recovery of California coastal sage scrub: American Midland Naturalist, v. 111, p. 105-117, https://doi.org/10.2307/2425548.","productDescription":"13 p.","startPage":"105","endPage":"117","numberOfPages":"13","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":130185,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Santa Monica Mountains","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -119.15076393254975,\n              34.2720286815771\n            ],\n            [\n              -119.15076393254975,\n              33.98965067077958\n            ],\n            [\n              -118.12202439621663,\n              33.98965067077958\n            ],\n            [\n              -118.12202439621663,\n              34.2720286815771\n            ],\n            [\n              -119.15076393254975,\n              34.2720286815771\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"111","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad5e4b07f02db683a7e","contributors":{"authors":[{"text":"Keeley, Jon E. 0000-0002-4564-6521 jon_keeley@usgs.gov","orcid":"https://orcid.org/0000-0002-4564-6521","contributorId":1268,"corporation":false,"usgs":true,"family":"Keeley","given":"Jon","email":"jon_keeley@usgs.gov","middleInitial":"E.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":315968,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Keeley, Sterling C.","contributorId":112968,"corporation":false,"usgs":true,"family":"Keeley","given":"Sterling","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":315967,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Coal-rich gravel bars and flood-plain debris are common below tributaries. Using a combination of techniques including channel-geometry and bar measurements, sediment sampling for rock-debris and coal size distributions, and botanical dating of flood events and geomorphic features, an average annual yield of 65 metric tons per square kilometer (187 tons per square mile) for tractively moved sediment has been calculated for the period 1977 to 1982. This value, 8 percent of the total sediment load, is probably an underestimate owing to the method of calculation. Slightly more than half of the traction load is coal, which moves through the basin within a few years. Rock debris, however, appears to require years to decades to move similar distances.","conferenceTitle":"Water for Resource Development, Proceedings of the Conference.","conferenceLocation":"Coeur D'Alene, ID, USA","language":"English","publisher":"ASCE","publisherLocation":"New York, NY, USA","isbn":"0872624099","usgsCitation":"Osterkamp, W.R., Carey, W.P., Hupp, C., and Bryan, B., 1984, Movement of tractive sediment from disturbed lands, Water for Resource Development, Proceedings of the Conference., Coeur D'Alene, ID, USA, p. 59-63.","productDescription":"5 p.","startPage":"59","endPage":"63","numberOfPages":"5","costCenters":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"links":[{"id":220240,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Tennessee","county":"Scott","otherGeospatial":"Smoky Creek basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -84.47250366210938,\n              36.15118243124803\n            ],\n            [\n              -84.28024291992188,\n              36.15118243124803\n            ],\n            [\n              -84.28024291992188,\n              36.40691545663981\n            ],\n            [\n              -84.47250366210938,\n              36.40691545663981\n            ],\n            [\n              -84.47250366210938,\n              36.15118243124803\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4af6e4b0c8380cd691bb","contributors":{"editors":[{"text":"Schreiber David L.","contributorId":128421,"corporation":true,"usgs":false,"organization":"Schreiber David L.","id":536266,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Osterkamp, W.

The distribution of vents maps the areal zonation inferred for the upper parts of the Coso magmatic system. Subalkalic basalts (&lt;50% SiO<sub>2</sub>) were erupted well away from the rhyolite field at any given time. Compositional variation among these basalts can be ascribed to crystal fractionation. Erupted volumes of these basalts decrease with increasing differentiation. Mafic lavas containing up to 58% SiO<sub>2</sub>, erupted adjacent to the rhyolite field, formed by mixing of basaltic and silicic magma. Basaltic magma interacted with crustal rocks to form other SiO<sub>2</sub>-rich mafic lavas erupted near the Sierra Nevada fault zone.</p><p class=\"Para\">Several rhyolite domes in the Coso volcanic field contain sparse andesitic inclusions (55–61% SiO<sub>2</sub>). Pillow-like forms, intricate commingling and local diffusive mixing of andesite and rhyolite at contacts, concentric vesicle distribution, and crystal morphologies indicative of undercooling show that inclusions were incorporated in their rhyolitic hosts as blobs of magma. Inclusions were probably dispersed throughout small volumes of rhyolitic magma by convective (mechanical) mixing. Inclusion magma was formed by mixing (hybridization) at the interface between basaltic and rhyolitic magmas that coexisted in vertically zoned igneous systems. Relict phenocrysts and the bulk compositions of inclusions suggest that silicic endmembers were less differentiated than erupted high-silica rhyolite. Changes in inferred endmembers of magma mixtures with time suggest that the steepness of chemical gradients near the silicic/mafic interface in the zoned reservoir may have decreased as the system matured, although a high-silica rhyolitic cap persisted.</p><p class=\"Para\">The Coso example is an extreme case of large thermal and compositional contrast between inclusion and host magmas; lesser differences between intermediate composition magmas and inclusions lead to undercooling phenomena that suggest smaller ΔT. Vertical compositional zonation in magma chambers has been documented through study of products of voluminous pyroclastic eruptions.

Glacial Priest Lake, dammed in the Priest River valley by a tongue of the Purcell trench lobe of the Cordilleran ice sheet, generally accumulated varved mud; the varved mud is sharply interrupted by 14 sand beds deposited by upvalley-running currents. The sand beds are texturally and structurally similar to slackwater sediment in valleys in southern Washington that were backflooded by outbursts from glacial Lake Missoula. Beds of varved mud also accumulated in glacial Lake Spokane (or Columbia?) in Latah Creek valley and elsewhere in northeastern Washington; the mud beds were disrupted, in places violently, during emplacement of each of 16 or more thick flood-gravel beds. This history corroborates evidence from southern Washington that only one graded bed is deposited per flood, refuting a conventional idea that many beds accumulated per flood. The total number of such floodlaid beds in stratigraphic succession near Spokane is at least 28. The mud beds between most of the floodlaid beds in these valleys each consist of between 20 and 55 silt-to-clay varves.

The Antarctic calcites (?? 18O(SMOW) = +9.14 to +11.82%0) were deposited from waters enriched in 16O whose isotopic composition was consistent with that of meteoric precipitation at low temperature and high latitude. The carbon of the calcite cleats (?? 13C(PDB) = -15.6 to -16.9%0) was derived in part from the coal (?? 13C(PDB) = -23.5 to -26.7%0) as carbon dioxide and by oxidation of methane or other hydrocarbon gases. The strontium ( 87Sr 86Sr = 0.71318-0.72392) originated primarily from altered feldspar grains in the sandstones of the Beacon Supergroup. Calcite cleats in the Kittaning No. 6 coal seam of Ohio (?? 18O(SMOW) = +26.04 to +27.79%0) were deposited from waters that had previously exchanged oxygen, possibly with marine carbonate at depth.

The organic carbon input into the central Aleutian Trench, based on carbon analyses of DSDP Legs 18 and 19 core samples, suggests that the average organic carbon content within the accretionary body is approximately 0.3-0.6%. Heat flow across the Aleutian Terrace indicates that at present the oil generation window lies at a depth of 3-6.5 km. At depths of 8 km (which corresponds to the maximum depth the offscraped sediment has been seismically resolved beneath the lower trench slope), the probable high (170-180??C) temperatures prohibit all but gas generation. The dewatering of trench sediment and subducted oceanic crust should produce an abundance of fluids circulating within the accretionary body. These fluids and gases can conduct hydrocarbons to any of the abundant trapping geometries or be lost from the system through sea floor seepage. In the Aleutian accretionary body all the conditions necessary for the formation of oil and gas deposits exist. The size and ultimate preservation of these deposits, however, are dependent on the deformational history of the prism both during accretion and after the accretion process has been superceded by subsequent tectonic regimes. ?? 1984.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Marine and Petroleum Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/0264-8172(84)90083-7","issn":"02648172","usgsCitation":"McCarthy, J., Stevenson, A., Scholl, D., and Vallier, T., 1984, Speculations on the petroleum geology of the accretionary body: an example from the central Aleutians: Marine and Petroleum Geology, v. 1, no. 2, p. 151-167, https://doi.org/10.1016/0264-8172(84)90083-7.","startPage":"151","endPage":"167","numberOfPages":"17","costCenters":[],"links":[{"id":268658,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0264-8172(84)90083-7"},{"id":220577,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"1","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b95b8e4b08c986b31b0a0","contributors":{"authors":[{"text":"McCarthy, J.","contributorId":50290,"corporation":false,"usgs":true,"family":"McCarthy","given":"J.","affiliations":[],"preferred":false,"id":365655,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stevenson, A.J.","contributorId":27864,"corporation":false,"usgs":true,"family":"Stevenson","given":"A.J.","email":"","affiliations":[],"preferred":false,"id":365654,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Scholl, D.W.","contributorId":106461,"corporation":false,"usgs":true,"family":"Scholl","given":"D.W.","email":"","affiliations":[],"preferred":false,"id":365657,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Vallier, T.L.","contributorId":69526,"corporation":false,"usgs":true,"family":"Vallier","given":"T.L.","affiliations":[],"preferred":false,"id":365656,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

This simple procedure involved passing a 50-100-mL sample through a bonded-phase extraction column, eluting the trapped organic compounds from the column with 2-4 mL of solvent, and evaporating the sample to 100 ??L with a stream of dry nitrogen, after which the sample was ready for gas chromatography/mass spectrometry analysis. Representative compounds indicative of creosote contamination were used for recovery and precision studies from the cyclohexyl-bonded phase. Recovery of these compounds from n-octyl-, n-octadecyl-, cyclohexyl-, and phenyl-bonded phases was compared. The bonded phase that exhibited the best recovery and least bias toward acidic or basic cmpounds was the n-octadecyl phase. Detailed compound Identification Is given for compounds Isolated from creosote- and pentachlorophenol-contaminated groundwater using the cyclohexyl-bonded phase.","language":"English","publisher":"American Chemical Society","doi":"10.1021/ac00278a052","issn":"00032700","usgsCitation":"Rostad, C., Pereira, W.E., and Ratcliff, S., 1984, Bonded-phase extraction column isolation of organic compounds in groundwater at a hazardous waste site: Analytical Chemistry, v. 56, no. 14, p. 2856-2860, https://doi.org/10.1021/ac00278a052.","productDescription":"5 p.","startPage":"2856","endPage":"2860","numberOfPages":"5","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":220358,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":269216,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/ac00278a052"}],"volume":"56","issue":"14","noUsgsAuthors":false,"publicationDate":"2002-05-01","publicationStatus":"PW","scienceBaseUri":"5059f1fbe4b0c8380cd4af38","contributors":{"authors":[{"text":"Rostad, C.E.","contributorId":50939,"corporation":false,"usgs":true,"family":"Rostad","given":"C.E.","email":"","affiliations":[],"preferred":false,"id":365473,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pereira, W.

Digital masking procedures were used to exclude shadow areas and vegetation and thus to produce a CRC image suitable for testing the new TM bands as a means to map hydrothermally altered rocks. Field examination of a masked CRC image revealed that several different types of altered rocks displayed hues associated with spectral characteristics common to hydroxyl-bearing minerals. Several types of unaltered rocks also displayed similar hues.","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":"Podwysocki, M.H., Power, M.S., Salisbury, J., and Jones, O.D., 1984, EVALUATION OF LOW-SUN ILLUMINATED LANDSAT-4 THEMATIC MAPPER DATA FOR MAPPING HYDROTHERMALLY ALTERED ROCKS IN SOUTHERN NEVADA., Proceedings of the International Symposium on Remote Sensing of Environment, Third Thematic Conference: Remote Sensing for Exploration Geology., Colorado Springs, CO, USA, p. 541-551.","startPage":"541","endPage":"551","numberOfPages":"11","costCenters":[],"links":[{"id":225619,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a046ae4b0c8380cd50983","contributors":{"authors":[{"text":"Podwysocki, Melvin H.","contributorId":60220,"corporation":false,"usgs":true,"family":"Podwysocki","given":"Melvin","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":367503,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Power, Marty S.","contributorId":93636,"corporation":false,"usgs":true,"family":"Power","given":"Marty","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":367504,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Salisbury, Jack","contributorId":96426,"corporation":false,"usgs":true,"family":"Salisbury","given":"Jack","email":"","affiliations":[],"preferred":false,"id":367505,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Jones, O.

A color-balanced 'standard' color-composite image is first produced using any desired contrast stretching algorithm. The stretched digital data are then transformed into the cylindrical Munsell color space. An enhanced version of a color-composite image is produced by stretching the saturation parameter over the full digital range and inverting the modified Munsell coordinates to red-blue-green (tristimulus) data space. The resulting image has greater color-saturation contrast than the original image, without hue change. Contrast stretching in Munsell color space reduces the correlation between individual bands or ratios and is similar to decorrelation processing based on principal-components transforms. However, principal components are based on data variance, with less variance being explained by each higher order component.","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":"Kruse, F.A., and Raines, G.L., 1984, TECHNIQUE FOR ENHANCING DIGITAL COLOR IMAGES BY CONTRAST STRETCHING IN MUNSELL COLOR SPACE., Proceedings of the International Symposium on Remote Sensing of Environment, Third Thematic Conference: Remote Sensing for Exploration Geology., Colorado Springs, CO, USA, p. 755-760.","startPage":"755","endPage":"760","numberOfPages":"6","costCenters":[],"links":[{"id":225751,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba37be4b08c986b31fd05","contributors":{"authors":[{"text":"Kruse, Fred A.","contributorId":26811,"corporation":false,"usgs":true,"family":"Kruse","given":"Fred","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":367525,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Raines, Gary L.","contributorId":48162,"corporation":false,"usgs":true,"family":"Raines","given":"Gary","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":367526,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
