Radiocarbon dates indicate that the Holocene sea transgressed the emergent reef platform by about 8000 yr B.P. The reef grew rapidly upward (about 5 to 10 mm/yr) until about 6500 yr B.P. Afterward vertical growth slowed to about 0.5 mm/yr, then lateral development became dominant during the last several thousand years. The second interval is dated at 131,000 ?? 3000 yr B.P. by uranium series. This unit correlates with oxygen-isotope substage 5e and with terrace VIIa of Huon Peninsula, New Guinea, and of Main Reef-2 terrace at Atauro Island. The third interval is not dated because corals were recrystallized and it is tentatively correlated with either oxygen-isotope stages 7 or 9. The age of the fourth interval is estimated at 454,000 ?? 100,000 yr B.P. from measured  234U 238U activity ratios.

The low strength of this granite is due to the alteration of biotite and chlorite montmorillonite. Deep weathering probably occurs in most granites, although we cannot rule out some anomalous mechanisms at Hi Vista. Geophysical instruments set in these slightly altered rocks are limited by the unstable behavior of the rocks. Thus, tectonic signals from instruments placed in shallow boreholes give vague results. Geophysical measurements of these weathered rocks resemble measurements of granitic rocks near major faults. The rheology of the rocks in which instruments are placed limits the useful sensitivity of the instruments. ?? 1985 Birkha??user Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Pure and Applied Geophysics PAGEOPH","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Birkha??user-Verlag","doi":"10.1007/BF00874609","issn":"00334553","usgsCitation":"Stierman, D., and Healy, J.H., 1985, A study of the depth of weathering and its relationship to the mechanical properties of near-surface rocks in the Mojave Desert: Pure and Applied Geophysics PAGEOPH, v. 122, no. 2-4, p. 425-439, https://doi.org/10.1007/BF00874609.","startPage":"425","endPage":"439","numberOfPages":"15","costCenters":[],"links":[{"id":205030,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00874609"},{"id":220359,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"122","issue":"2-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e5c2e4b0c8380cd46f6c","contributors":{"authors":[{"text":"Stierman, D.J.","contributorId":54621,"corporation":false,"usgs":true,"family":"Stierman","given":"D.J.","email":"","affiliations":[],"preferred":false,"id":365475,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Healy, J.

Ten monitoring stations deployed to date have shown that anomalous H2 emissions take place occasionally in addition to diurnal changes. Among the ten sites, the Cienega Winery site has produced data that are characterized by very small diurnal changes, a stable baseline, and remarkably distinct spike-like H2 anomalies since its installation in July 1982. A major peak appeared on 1-10 November 1982, and another on 3 April 1983, and a medium peak on 1 November 1983. The occurrences of these peaks coincided with periods of very low seismicity within a radius of 50 km from the site. In order to methodically assess how these peaks are related to earthquakes, three H2 degassing models were examined. A plausible correlational pattern was obtained by using a model that (1) adopts a hemicircular spreading pattern of H2 along an incipient fracture plane from the hypocenter of an earthquake, (2) relies on the FeO-H2O reaction for H2 generation, and (3) relates the accumulated amount of H2 to the mass of serpentinization of underlying ophiolitic rocks; the mass was tentatively assumed to be proportional to the seismic energy of the earthquake. ?? 1985 Birkha??user Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Pure and Applied Geophysics PAGEOPH","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Birkha??user-Verlag","doi":"10.1007/BF00874606","issn":"00334553","usgsCitation":"Sato, M., Sutton, A.J., and McGee, K., 1985, Anomalous hydrogen emissions from the San Andreas fault observed at the Cienega Winery, central California: Pure and Applied Geophysics PAGEOPH, v. 122, no. 2-4, p. 376-391, https://doi.org/10.1007/BF00874606.","startPage":"376","endPage":"391","numberOfPages":"16","costCenters":[],"links":[{"id":205627,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00874606"},{"id":225420,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"122","issue":"2-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ec48e4b0c8380cd49188","contributors":{"authors":[{"text":"Sato, M.","contributorId":50201,"corporation":false,"usgs":true,"family":"Sato","given":"M.","email":"","affiliations":[],"preferred":false,"id":367476,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sutton, A.

The tectonized peridotite lower unit of the ophiolite is intruded by felsic dikes and pods including isolated lenses of massive rodingite, small bodies of strongly deformed diorite, and younger, less deformed quartz monzonite. These intrusions are found only near the base of the ophiolite, do not intrude the surrounding country rock, and are rootless; for these reasons they are considered to have been emplaced in the ophiolite before it reached its present location.The younger group of intrusions consists of biotite–muscovite quartz monzonite and leuco–quartz monzonite. Analyzed samples have high K</span><sub>2</sub><span>O contents, high (K</span><sub>2</sub><span>O × 100)/(Na</span><sub>2</sub><span>O + K</span><sub>2</sub><span>O) ratios, and high initial strontium ratios (0.7171–0.7179), indicating that the magma source region was continental and that these felsic rocks formed by partial melting of continental sediments. Whole-rock and mineral isochron ages suggest that the felsic intrusions are about 456 ± 4 Ma old and that they were metamorphosed about 418 ± 7 Ma ago.The detachment of the ophiolite occurred about 491 ± 3 Ma ago and is recorded by the age of the metamorphic aureole beneath the ophiolite. The felsic dikes were intruded some 35 Ma years later during the Taconic Orogeny. The lengthy time between detachment and final nappe emplacement recorded by the felsic dikes may be a requirement for the formation of abundant asbestiform chrysotile.</span></p>","language":"English","publisher":"Canadian Science Publishing","doi":"10.1139/e85-130","issn":"00084077","usgsCitation":"Clague, D., Frankel, C., and Eaby, J., 1985, The age and origin of felsic intrusions of the Thetford Mines ophiolite, Quebec: Canadian Journal of Earth Sciences, v. 22, no. 9, p. 1257-1261, https://doi.org/10.1139/e85-130.","productDescription":"5 p.","startPage":"1257","endPage":"1261","costCenters":[],"links":[{"id":220408,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Canada","state":"Quebec","city":"Thetford Mines","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -71.53395448413819,\n              46.17541878757814\n            ],\n            [\n              -71.53395448413819,\n              45.98387893387692\n            ],\n            [\n              -71.08132800656608,\n              45.98387893387692\n            ],\n            [\n              -71.08132800656608,\n              46.17541878757814\n            ],\n            [\n              -71.53395448413819,\n              46.17541878757814\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"22","issue":"9","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba9aae4b08c986b32240a","contributors":{"authors":[{"text":"Clague, D.A.","contributorId":36129,"corporation":false,"usgs":true,"family":"Clague","given":"D.A.","email":"","affiliations":[],"preferred":false,"id":365374,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Frankel, C.S.","contributorId":57593,"corporation":false,"usgs":true,"family":"Frankel","given":"C.S.","email":"","affiliations":[],"preferred":false,"id":365375,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Eaby, J.S.","contributorId":93053,"corporation":false,"usgs":true,"family":"Eaby","given":"J.S.","email":"","affiliations":[],"preferred":false,"id":365376,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Calcium ions are the predominant cationic species; sulfate is the major anionic constituent. Bulk precipitation major ion concentrations exhibit log-normal distributions. Representative mean and standard deviation values for the major inorganic ionic species present in bulk precipitation have been calculated for three years of consecutive seasons. Standard deviations for all species, except nitrate, are similar. For two years of data grouped into quarters, deviations from mean values fall well within the plus or minus two standard deviation limit.

In contrast to the mid-ocean ridge basalts (MORB), the Pb-isotopic data for several of the formations form small, tight clusters, and the Nd- and Sr-isotopic data show discrete variation between these basalt groups. Pseudoisochrons are not observed. A single model will account for the observed isotopic and trace-element data from samples from most of the Columbia River Basalt Group. This model calls for partial melting of the convecting oceanic-type mantle and mixing with, or contamination by, fluids derived from continental-derived sediments. It requires that crustal components are not only subducted along the trench, but that they are also transported in the low-velocity zone of the mantle at least 400 km behind the active volcanic arc into the back-arc environment represented by the Columbia Plateaus province.</p><p>Lead isotopes in the Saddle Mountains Basalt, the youngest formation, suggest that these magmas were formed by partial melting of a 2.6-b.y.-old subcontinental lithosphere that extends as far west as south-central Washington near Ice Harbor Dam. The source material for these flows is characterized by high Th/U, Th/Pb, Rb/Sr, and Nd/Sm ratios and light REE enrichment. An additional component, presumably granitic crust, is necessary to explain the Pb-isotopic data of the Umatilla and perhaps the Pomona Members of the Saddle Mountains Basalt. This contamination model is supported by published δ<sup>18</sup>O data and petrological interpretation. Published studies of basalts from the Deccan Traps, the Tasmanian dolerites, the Snake River Group, and the volcanics of the Yellowstone Plateau province also suggest that melting of old subcontinental lithosphere beneath the continental crust may be an important process in basalt genesis on a global scale.</p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1985)96<676:GIOLDF>2.0.CO;2","usgsCitation":"Church, S.E., 1985, Genetic interpretation of lead-isotopic data from the Columbia River basalt group, Oregon, Washington, and Idaho: Geological Society of America Bulletin, v. 96, no. 5, p. 676-690, https://doi.org/10.1130/0016-7606(1985)96<676:GIOLDF>2.0.CO;2.","productDescription":"15 p.","startPage":"676","endPage":"690","numberOfPages":"15","costCenters":[],"links":[{"id":219982,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Idaho, Oregon, Washington","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -125.65665057981707,\n              48.79681398123117\n            ],\n            [\n              -125.65665057981707,\n              41.36535877621472\n            ],\n            [\n              -113.35196307981691,\n              41.36535877621472\n            ],\n            [\n              -113.35196307981691,\n              48.79681398123117\n            ],\n            [\n              -125.65665057981707,\n              48.79681398123117\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"96","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a157be4b0c8380cd54e2f","contributors":{"authors":[{"text":"Church, S.

Detailed analyses of deeply-buried chalk from core of the Smoky Hill Chalk Member of the Niobrara Formation in the Champlin Petroleum 2 Boxelder Farms well combined with core data from other Niobrara wells have helped identify many depositional and diagenetic relationships. Porosity of the chalk is proportional to maximum burial depth and inversely proportional to the amount of non-carbonate material (acid- insoluble residue content) in the chalk. Total organic carbon content in the chalk is proportional to the amount of acid-insoluble residue and relative abundance of pyrite in the acid-insoluble fraction. Quartz is inversely proportional to the amount of insoluble material, and the amount of clay tends to increase as insolubles increase, suggesting that detritus in these chalks is greatly influenced by reworked, altered, volcanic products rather than siliceous clastics.-from Authors","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Mountain Geologist","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"0027254X","usgsCitation":"Pollastro, R.M., and Martinez, C., 1985, Mineral, chemical and textural relationships in rhythmic-bedded, hydrocarbon-productive chalk of the Niobrara Formation, Denver Basin, Colorado ( USA).: Mountain Geologist, v. 22, no. 2, p. 55-63.","startPage":"55","endPage":"63","numberOfPages":"9","costCenters":[],"links":[{"id":220257,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"22","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5a64e4b0c8380cd6ee60","contributors":{"authors":[{"text":"Pollastro, R.

Areas of maximum metamorphic intensity within the T-3 domain coincide with areas of maximum crustal thickening resulting from imbricate thrusting (Berkshire massif) or from recumbent folding (Manhattan Prong) of remobilized North American continental crust in the later stages of the Taconic orogeny.</p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1985)96<123:AAKDBO>2.0.CO;2","usgsCitation":"Sutter, J.F., Ratcliffe, N.M., and Mukasa, S., 1985, 40Ar/39Ar and K-Ar data bearing on the metamorphic and tectonic history of western New England: Geological Society of America Bulletin, v. 96, no. 1, p. 123-136, https://doi.org/10.1130/0016-7606(1985)96<123:AAKDBO>2.0.CO;2.","productDescription":"14 p.","startPage":"123","endPage":"136","numberOfPages":"14","costCenters":[],"links":[{"id":220304,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -73.71683860031261,\n              43.14936147487742\n            ],\n            [\n              -73.71683860031261,\n              41.42652808796893\n            ],\n            [\n              -72.88187766281217,\n              41.42652808796893\n            ],\n            [\n              -72.88187766281217,\n              43.14936147487742\n            ],\n            [\n              -73.71683860031261,\n              43.14936147487742\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"96","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e264e4b0c8380cd45b3a","contributors":{"authors":[{"text":"Sutter, J.

A generalized viscoplastic fluid model that has both parts as well as two major rheological properties (i. e. , the normal stress effect and soil yield criteria) is shown to be sufficiently accurate, yet practical, for general use in debris flow modeling. Other rheological models, such as the Bingham plastic fluid model and the so-called Coulomb-viscous model, are compared in terms of the generalized viscoplastic fluid model.","conferenceTitle":"Hydraulics and Hydrology in the Small Computer Age, Proceedings of the Specialty Conference.","conferenceLocation":"Lake Buena Vista, FL, USA","language":"English","publisher":"ASCE","publisherLocation":"New York, NY, USA","isbn":"0872624749","usgsCitation":"Chen, C., 1985, PRESENT STATUS OF RESEARCH IN DEBRIS FLOW MODELING., Hydraulics and Hydrology in the Small Computer Age, Proceedings of the Specialty Conference., Lake Buena Vista, FL, USA, p. 733-741.","startPage":"733","endPage":"741","numberOfPages":"9","costCenters":[],"links":[{"id":220303,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a7375e4b0c8380cd7704d","contributors":{"authors":[{"text":"Chen, Cheng-lung","contributorId":30752,"corporation":false,"usgs":true,"family":"Chen","given":"Cheng-lung","email":"","affiliations":[],"preferred":false,"id":365906,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
