Many low‐angle faults previously mapped as thrusts invariably juxtapose younger over older rocks, suggesting a normal sense of offset. We infer that serpentinite melange that is present structurally beneath the Coast Range ophiolite formed above the subduction zone during convergence and was subsequently faulted and further attenuated with upper plate rocks concurrent with extension. Franciscan blueschist‐facies rock is inferred to have been transported from depth to higher structural levels concurrent with underplating and extensional unroofing in the upper plate. The present juxta‐position of the Coast Range ophiolite and Great Valley sequence with Franciscan rocks is commonly controlled by Neogene high‐angle faults. We propose that the term Coast Range thrust is no longer appropriate and that the name should be changed to Coast Range fault.</span></p>","publisher":"American Geophysical Union","doi":"10.1029/TC006i004p00475","usgsCitation":"Jayko, A.S., Blake, M.C., and Harms, T., 1987, Attenuation of the Coast Range ophiolite by extensional faulting and nature of the Coast Range \"thrust,\" California: Tectonics, v. 6, p. 475-488, https://doi.org/10.1029/TC006i004p00475.","productDescription":"14 p.","startPage":"475","endPage":"488","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":355116,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","volume":"6","noUsgsAuthors":false,"publicationDate":"2010-07-26","publicationStatus":"PW","scienceBaseUri":"5c1134ece4b034bf6a827710","contributors":{"authors":[{"text":"Jayko, A.

Some applications are 1) interpretation of lava-flow structures, stratigraphic complexities, and petrologic relations in older volcanic units; 2) interpretation of bulk properties of the mantle and constraints on partial melting and deep magma transport; 3) interpretation of geophysical characteristics of potentially active volcanic systems; 4) direct determination of physical properties of molten and solidified basalt, and of intensive variables (e.g., oxygen fugacity and temperature) accompanying cooling and crystallization; 5) quantitative assessment of crystal fractionation and magma mixing, 6) tests of theoretical and experimental geochemical, geophysical, and rheologic models of volcanic behavior; and 7) confirmation in nature of laboratory experiments related to crystallization in igneous systems. The critical factors that make real-time study of volcanic activity valuable are that the location and timing of events are known, and that molten rock and gases are available for direct observation and sampling for subsequent study. Observations made over a period of time make it possible to calculate rates of magma transport, storage, and crystallization, as well as to quantitatively determine elastic and inelastic deformation and the build up and decay of stress within the active volcanic system.

Near Barrel Spring, in the southwest part of the basin, both dinosaur bone and Paleocene pollen have been found. One bone, found at the top of the Ojo Alamo, was loose on the surface, and its significance is therefore equivocal. Dinosaur bone, however, has also been found in place in the upper part of the Ojo Alamo about 1.6 km (1 mi) west of Barrel Spring, at about the same stratigraphic level as Paleocene pollen from a site just east of Barrel Spring. Because there is no apparent unconformity between the highest in-place bone level and the Paleocene pollen level in this area, the Ojo Alamo dinosaurs, if not reworked, are Paleocene in age at this site and probably throughout the San Juan Basin.</p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/SPE209-p17","usgsCitation":"Fassett, J.E., Lucas, S.G., and O’Neill, F., 1987, Dinosaurs, pollen and spores, and the age of the Ojo Alamo Sandstone, San Juan Basin, New Mexico: GSA Special Papers, v. 209, p. 17-34, https://doi.org/10.1130/SPE209-p17.","productDescription":"18 p.","startPage":"17","endPage":"34","costCenters":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":370321,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Colorado, New Mexico","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -108.709716796875,\n              35.93354064249312\n            ],\n            [\n              -106.864013671875,\n              35.93354064249312\n            ],\n            [\n              -106.864013671875,\n              37.45741810262938\n            ],\n            [\n              -108.709716796875,\n              37.45741810262938\n            ],\n            [\n              -108.709716796875,\n              35.93354064249312\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"209","noUsgsAuthors":false,"publicationDate":"1987-01-01","publicationStatus":"PW","contributors":{"authors":[{"text":"Fassett, James E. jfassett@usgs.gov","contributorId":73590,"corporation":false,"usgs":true,"family":"Fassett","given":"James","email":"jfassett@usgs.gov","middleInitial":"E.","affiliations":[{"id":165,"text":"Central Energy Resources Team","active":false,"usgs":true}],"preferred":false,"id":777646,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lucas, S.

These formations have been known to be Late Cretaceous in age since the early 1900s. Now, with the greatly renewed interest in rocks adjacent to mass extinction boundaries, it is important to place more precise ages on such rock units as the Fruitland and Kirtland. Deposition of the Fruitland and Kirtland was closely related to deposition of the underlying marine-regressive Pictured Cliffs Sandstone. Because the Pictured Cliffs was deposited as a strandline sandstone in a subsiding seaway, its stratigraphic expression, when related to a time horizon (the Huerfanito Bentonite Bed), is a series of rising-to-the-northeast, time transgressive, stair steps. Thus, time lines (or horizons) drawn parallel to the Huerfanito cut through the marine Lewis Shale, the strandline Pictured Cliffs Sandstone, and the continental Fruitland Formation and Kirtland Shale.</p><p>Ammonites have been collected and identified from various stratigraphic levels within the Lewis Shale around the northwest, north, and east sides of the San Juan Basin. These fossils can be tied in to the established ammonite zonation of the Western Interior seaway. Because some of these ammonite zones have been radiometrically dated outside the San Juan Basin, it is possible to project these dated faunal zones from the Lewis Shale along time lines into the Fruitland Formation and Kirtland Shale and thereby estimate the age of those rocks. Based on these projections the part of the Fruitland and Kirtland laterally time-equivalent to the Lewis Shale is estimated to range from 73.2 ± 0.7 Ma to 73.9 ± 0.8 Ma. The average age for this interval based on these dates is 73.5 ± 0.5 Ma; the maximum range of the interval at the 95 percent confidence level is 71.8 to 75.5 Ma. This age range puts these rocks in the Campanian Stage of the upper Cretaceous in the San Juan Basin.</p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/SPE209-p5","usgsCitation":"Fassett, J.E., 1987, The ages of the continental, Upper Cretaceous, Fruitland Formation and Kirtland Shale based on a projection of ammonite zones from the Lewis Shale, San Juan Basin, New Mexico and Colorado: GSA Special Papers, v. 209, p. 5-16, https://doi.org/10.1130/SPE209-p5.","productDescription":"12 p.","startPage":"5","endPage":"16","costCenters":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":370320,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Colorado, New Mexic","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -108.709716796875,\n              36.02244668175846\n            ],\n            [\n              -106.8695068359375,\n              36.02244668175846\n            ],\n            [\n              -106.8695068359375,\n              37.48793540168987\n            ],\n            [\n              -108.709716796875,\n              37.48793540168987\n            ],\n            [\n              -108.709716796875,\n              36.02244668175846\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"209","noUsgsAuthors":false,"publicationDate":"1987-01-01","publicationStatus":"PW","contributors":{"authors":[{"text":"Fassett, James E. jfassett@usgs.gov","contributorId":73590,"corporation":false,"usgs":true,"family":"Fassett","given":"James","email":"jfassett@usgs.gov","middleInitial":"E.","affiliations":[{"id":165,"text":"Central Energy Resources Team","active":false,"usgs":true}],"preferred":false,"id":777680,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

In inverting the surface deformation data to obtain the slip distribution, the Earth is generally approximated by an elastic half‐space. Slip distributions inferred from a half‐space model may contain artifacts, including zones of reversed slip, due solely to effects of layering in the real Earth. This effect is demonstrated for a vertical strike‐slip fault in an Earth consisting of an elastic layer overlying an elastic half‐space. Slip on the fault is taken to be independent of the along‐strike coordinate (i.e., antiplane strain is assumed). For a given slip distribution in this model the slip distribution on a similar fault in an elastic half‐space is found that produces the identical surface deformation. Comparison of the two slip distributions reveals structure introduced into the half‐space equivalent slip profile by crustal layering. The comparisons suggest that low‐resolution inversion schemes (e.g., single screw dislocation models) are not drastically affected by Earth structure, but attempts at detailed inversion are likely to produce profiles contaminated by artifacts of Earth structure.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB092iB10p10595","usgsCitation":"Savage, J.C., 1987, Effect of crustal layering upon dislocation modeling: Journal of Geophysical Research B: Solid Earth, v. 92, no.

Before developing a plan for the refuge, the Secretary shall \"identify and describe--a) the populations and habitats of the fish and wildlife resources of the refuge; b) the special values of the refuge as well as any other archeological, cultural, ecological, geological , historical, palentological, scenic, or wilderness value of the refuge; c) areas within the refuge that are suitable for use as administrative sites or visitor facilities...; d) present the potential requirements for access with respect to the refuge...; and e) significant problems which may adversely affect the populations and habitats of fish and wildlife identified and described...\" (ANILCA, 1980).

Fish &amp; Wildlife Service (USFWS) has the responsibility for collecting the resource information to address the research, management, development and planning requirements identified in Section 304. Because of the brief period provided by the Act for data collection, habitat mapping, and habitat assessment, the USFWS in cooperation with the U.S. Geological Survey's EROS Field Office, used digital Landsat multispectral scanner (MSS) data and digital terrain data to produce land cover and terrain maps. A computer assisted digital analysis of Landsat MSS data was used because coverage by aerial photographs was incomplete for much of the refuge and because the level&nbsp;of detail obtained from&nbsp;Landsat data was adequate to meet most USFWS research, management and planning needs. Relative cost and time requirements were also factors in the decision to use the digital analysis approach.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston,

I also examined the effects of seasonal and environmental factors on nestling growth and survival and on hatching asynchrony. Nestlings in asynchronous broods were more likely to diverge in mass and did so at a faster rate than those in synchronous broods. The lightest nestlings of asynchronous broods grew more slowly than their heavier nestmates and than all nestlings in synchronous broods. Brood reduction occurred more frequently in asynchronous broods. Survival and growth rates decreased throughout the breeding season and during inclement weather. Hatching intervals increased during the season. When brood reduction or differential growth among nestmates occurred in asynchronous broods, suggesting that the energy available for growth was limiting, heavy nestlings in asynchronous broods grew nonsignificantly faster than heavy nestlings in concurrent synchronous broods. This trend implies that when insufficient food is delivered to nestlings, asynchronous hatching may provide a slight advantage for older nestlings. Growth rates of all nestlings, however, were greatest in highly synchronous broods. Explanations other than growth of young must be invoked to explain why extreme synchrony is not more common in goldfinches. I discuss constraints on the normal pattern of hatching asynchrony characteristic of this species. The proximate mechanism for differential feeding and brood reduction is discussed.</span></p>","language":"English","publisher":"Ecological Society of America","doi":"10.2307/1939866","usgsCitation":"Skagen, S.K., 1987, Hatching asynchrony in American Goldfinches: An experimental study: Ecology, v. 68, no. 6, p. 1747-1759, https://doi.org/10.2307/1939866.","productDescription":"13 p.","startPage":"1747","endPage":"1759","numberOfPages":"13","costCenters":[],"links":[{"id":292810,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"68","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53f8595ae4b03f038c5c1806","contributors":{"authors":[{"text":"Skagen, Susan Knight 0000-0002-6744-1244 skagens@usgs.gov","orcid":"https://orcid.org/0000-0002-6744-1244","contributorId":81811,"corporation":false,"usgs":true,"family":"Skagen","given":"Susan","email":"skagens@usgs.gov","middleInitial":"Knight","affiliations":[],"preferred":false,"id":499082,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

This system was used to issue warnings during the storms of 12 to 21 February 1986, which produced 800 millimeters of rainfall in the region. Although analysis after the storms suggests that modifications and additional developments are needed, the system successfully predicted the times of major landslide events. It could be used as a prototype for systems in other landslide-prone regions.</span></p>","language":"English","publisher":"American Association for the Advancement of Science","doi":"10.1126/science.238.4829.921","issn":"00368075","usgsCitation":"Keefer, D.K., Wilson, R.C., Mark, R.K., Brabb, E.E., Brown, W.M., Ellen, S.D., Harp, E.L., Wieczorek, G.F., Alger, C., and Zatkin, R., 1987, Real-time landslide warning during heavy rainfall: Science, v. 238, no. 4829, p. 921-925, https://doi.org/10.1126/science.238.4829.921.","productDescription":"5 p.","startPage":"921","endPage":"925","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":225562,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","city":"San Francisco","otherGeospatial":"San Francisco Bay region","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -122.6623705324246,\n              37.97712909139146\n            ],\n            [\n              -122.6623705324246,\n              37.37256131063128\n            ],\n            [\n              -121.91451351650927,\n              37.37256131063128\n            ],\n            [\n              -121.91451351650927,\n              37.97712909139146\n            ],\n            [\n              -122.6623705324246,\n              37.97712909139146\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"238","issue":"4829","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a95a5e4b0c8380cd81b4f","contributors":{"authors":[{"text":"Keefer, David K.","contributorId":22405,"corporation":false,"usgs":true,"family":"Keefer","given":"David","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":367954,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wilson, R.

Selenium concentrations in biota from the Reservoir and Drain (referred to here collectively as “Kesterson”) exceeded 300 (μg/g dry weight in some samples of algae, submerged rooted plants, chironomids, and mosquitofish, and were as high as 440 μg/g dry weight in decomposing detritus. Overall, selenium concentrations in samples from Kesterson averaged about 100-fold higher than those from the Volta Wildlife Area (here termed “Volta”), a nearby site that does not receive subsurface drainage water. Selenium concentrations generally increased from water to sediment to plants to animals. Spatial (geographic) patterns were observed for selenium concentrations in samples from Kesterson, but not in those from Volta. Higher concentrations were usually measured in samples from the San Luis Drain than from the evaporation ponds that comprise Kesterson Reservoir. At Kesterson, concentrations were usually higher in August than in May. The elevated levels of selenium measured in forage organisms from Kesterson are probably toxic to sensitive consumer animals, and may explain recent observations of dead and deformed embryos in eggs of aquatic birds that nest at the Reservoir. The effects of the selenium on fish living in subsurface agricultural drainage water are still poorly understood.</span></p>","language":"English","publisher":"Springer-Verlag","doi":"10.1007/BF01055416","usgsCitation":"Saiki, M.K., and Lowe, T.P., 1987, Selenium in aquatic organisms from subsurface agricultural drainage water, San Joaquin Valley, California: Archives of Environmental Contamination and Toxicology, v. 16, no. 6, p. 657-670, https://doi.org/10.1007/BF01055416.","productDescription":"14 p.","startPage":"657","endPage":"670","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":357751,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"San Joaquin Valley","volume":"16","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5c1134ede4b034bf6a827722","contributors":{"authors":[{"text":"Saiki, Michael K.","contributorId":54671,"corporation":false,"usgs":true,"family":"Saiki","given":"Michael","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":746319,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lowe, T.

Measurements of sodium chloride concentration (used as a tracer) were made at 105 in situ sampling locations in a new type of sand box designed to allow flow in either of two perpendicular directions. Two types of hydraulic anisotropy were examined. The first consisted of structured zones of increased hydraulic conductivity within a lower-conductivity medium. The second type involved low-conductivity platelike inclusions within a homogeneous, isotropic medium. The plates were aligned such that the tortuosity was increased only in one principal direction of permeability. Results using two examples of the first type of media showed that the apparent longitudinal dispersivities for flow parallel to the high-conductivity direction were greater than those perpendicular to this direction. Two examples of the second type of media produced smaller apparent longitudinal dispersivities for flow parallel to the high-conductivity direction. The results suggest that the mechanisms causing dispersive anisotropy can be related, conceptually, to the factors causing hydraulic anisotropy.</p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/WR023i011p02145","usgsCitation":"Silliman, S.E., Konikow, L.F., and Voss, C., 1987, Laboratory investigation of longitudinal dispersion in anisotropic porous media: Water Resources Research, v. 23, no. 11, p. 2145-2151, https://doi.org/10.1029/WR023i011p02145.","productDescription":"7 p.
