Although no field investigation was conducted in the Prescott National Forest to the west of the Verde River, a field investigation was conducted in the summer of 1994 by this author on the Coconino National Forest, to the east of the Verde River, where units of surficial materials of the same age and similar character are found (Cox, 1995). The intent of this evaluation of sand and gravel resources in the Prescott National Forest and adjacent areas in the Verde Valley, is to provide the land managers of the U.S. Forest Service with a map that delineates sand- and gravel-bearing geologic units. The map distinguishes (1) sand-and gravel-bearing units that are limited to channels from those that are not, (2) sand-and gravel-bearing units that are thin (generally less than 40 feet thick which is one contour interval on the topographic maps) from those that are locally thick (generally 40 feet or more), (3) sand- and gravel-bearing units that are poorly sorted from those that are well-sorted4, (4) sand- and gravel-bearing units that have little or no soil development from those that have greater degrees of soil development and lithification, (5) and sand- and gravel-bearing units that support riparian vegetation from those that do not. These distinctive characteristics are related to the geologic age or depositional setting of the rock materials and can be distinguished where areas are mapped in detail.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr99127","usgsCitation":"Cox, L.J., Bliss, J.D., and Miller, R.J., 1999, An evaluation of sand and gravel resources in and near the Prescott National Forest in the Verde Valley, Arizona, with a section on evaluation of sand and gravel resources using selected engineering variables: U.S. Geological Survey Open-File Report 99-127, Report: iv, 40 p.; 1 Plate: 36.00 x 48.00 inches; Readme; Dataset, https://doi.org/10.3133/ofr99127.","productDescription":"Report: iv, 40 p.; 1 Plate: 36.00 x 48.00 inches; Readme; Dataset","numberOfPages":"44","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":163158,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr99127.jpg"},{"id":403563,"rank":6,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_54572.htm","linkFileType":{"id":5,"text":"html"}},{"id":284819,"rank":4,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1999/0127/pdf/of99-127plate1.pdf","text":"Plate 1","linkFileType":{"id":1,"text":"pdf"}},{"id":284816,"rank":3,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1999/0127/pdf/OF99-127.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":284818,"rank":2,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/of/1999/0127/cverde.tar.Z"},{"id":284815,"rank":5,"type":{"id":20,"text":"Read Me"},"url":"https://pubs.usgs.gov/of/1999/0127/readme.txt"},{"id":3172,"rank":7,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1999/0127/","linkFileType":{"id":5,"text":"html"}}],"scale":"50000","projection":"Universal Transverse Mercator projection","datum":"National Geodetic Vertical Datum of 1929","country":"United States","state":"Arizona","county":"Coconino County, Yavapai County","otherGeospatial":"Prescott National Forest, Verde Valley","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -112.125,\n              34.625\n            ],\n            [\n              -111.875,\n              34.625\n            ],\n            [\n              -111.875,\n              34.875\n            ],\n            [\n              -112.125,\n              34.875\n            ],\n            [\n              -112.125,\n              34.625\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd4c85e4b0b290850f106c","contributors":{"authors":[{"text":"Cox, Leslie J.","contributorId":92692,"corporation":false,"usgs":true,"family":"Cox","given":"Leslie","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":207982,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bliss, James D. jbliss@usgs.gov","contributorId":2790,"corporation":false,"usgs":true,"family":"Bliss","given":"James","email":"jbliss@usgs.gov","middleInitial":"D.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":207981,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Miller, Robert J. rjmiller@usgs.gov","contributorId":2516,"corporation":false,"usgs":true,"family":"Miller","given":"Robert","email":"rjmiller@usgs.gov","middleInitial":"J.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":207980,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The terrain within this area is of low to moderate relief, ranging from 100 to more than 1000 ft above sea level. This area is largely rural, with most of the valley floor and low-relief foothills under cultivation. In the last decade, the rural areas outside the boundaries of established towns have experienced significant growth in new homes built and the expansion of housing subdivisions. This growth has placed an increased demand on existing geologic resources (e.g., groundwater, sand and gravel, crushed stone) and the need to better understand potential geologic hazards within this region.\n\nPrevious geologic mapping by Piper (1942), Peck and others (1964), Newton (1969), Hampton (1972), Miller and Orr (1984), Orr and Miller (1984), and Miller and Orr (1986, 1988) established and refined the general stratigraphic framework of this region. This mapping identified few faults or folds; earlier investigators were hindered by the lack of reliably identifiable marker horizons within the stratigraphic section. Werner (1991), using available seismic profile lines and well data in the Willamette Valley to locate the top of the Columbia River Basalt Group, was able to identify and map faults within the subsurface. Reconnaissance mapping of the Columbia River Basalt Group (CRBG) units in this region in the early 1980’s indicated that these stratigraphic units could serve as a series of unique reference horizons for identifying post-Miocene folding and faulting (Beeson and others, 1985, 1989; Beeson and Tolan, 1990).\n\nThe major emphasis of this investigation was to identify and map CRBG units within the Scotts Mills, Silverton, and Stayton NE quadrangles and to utilize this detailed CRBG stratigraphy to identify and characterize structural features.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr99141","usgsCitation":"Tolan, T., Beeson, M., and Wheeler, K.L., 1999, Geologic map of the Scotts Mills, Silverton, and Stayton Northeast 7.5 minute quadrangles, Northwest Oregon: A digital database: U.S. Geological Survey Open-File Report 99-141, Report: HTML document; Readme: HTML; Readme: TXT; Readme: PDF, 15 p.; Data package; All files: PS; All files: PDF; 2 Sheets: 31.50 x 34.19 inches and 41.50 x 33.50 inches, https://doi.org/10.3133/ofr99141.","productDescription":"Report: HTML document; Readme: HTML; Readme: TXT; Readme: PDF, 15 p.; Data package; All files: PS; All files: PDF; 2 Sheets: 31.50 x 34.19 inches and 41.50 x 33.50 inches","numberOfPages":"15","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":108395,"rank":10,"type":{"id":20,"text":"Read Me"},"url":"https://pubs.usgs.gov/of/1999/0141/readme.txt","linkFileType":{"id":5,"text":"html"},"description":"13262"},{"id":60309,"rank":9,"type":{"id":20,"text":"Read Me"},"url":"https://pubs.usgs.gov/of/1999/0141/readme.html","linkFileType":{"id":1,"text":"pdf"}},{"id":3173,"rank":8,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1999/0141/","linkFileType":{"id":5,"text":"html"}},{"id":284741,"rank":7,"type":{"id":20,"text":"Read Me"},"url":"https://pubs.usgs.gov/of/1999/0141/pdf/readme.pdf"},{"id":284742,"rank":4,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1999/0141/intro.html"},{"id":284744,"rank":3,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/of/1999/0141/sssofrpdf.tar.gz"},{"id":163252,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1999/0141/report-thumb.jpg"},{"id":284743,"rank":2,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/of/1999/0141/sssofr.tar.gz"},{"id":284746,"rank":6,"type":{"id":26,"text":"Sheet"},"url":"https://pubs.usgs.gov/of/1999/0141/pdf/stn.pdf","text":"Sheet 2"},{"id":284745,"rank":5,"type":{"id":26,"text":"Sheet"},"url":"https://pubs.usgs.gov/of/1999/0141/pdf/svsc.pdf","text":"Sheet 1"}],"scale":"24000","projection":"Universal Transverse Mercator projection","country":"United States","state":"Oregon","otherGeospatial":"Scott Mills, Silverton, Stayton","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -122.875,44.875 ], [ -122.875,45.125 ], [ -122.625833,45.125 ], [ -122.625833,44.875 ], [ -122.875,44.875 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd5d05e4b0b290850fadc6","contributors":{"authors":[{"text":"Tolan, Terry","contributorId":55489,"corporation":false,"usgs":true,"family":"Tolan","given":"Terry","affiliations":[],"preferred":false,"id":207986,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Beeson, Marvin","contributorId":102123,"corporation":false,"usgs":true,"family":"Beeson","given":"Marvin","affiliations":[],"preferred":false,"id":207987,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wheeler, Karen L. kwheeler@usgs.gov","contributorId":3404,"corporation":false,"usgs":true,"family":"Wheeler","given":"Karen","email":"kwheeler@usgs.gov","middleInitial":"L.","affiliations":[],"preferred":true,"id":207985,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The region was subject in historical times to large magnitude earthquakes and devastating tsunamis. A major downward tilt of the sea floor north of Puerto Rico and the Virgin Islands, large submarine rockslides, and an unusually large negative gravity anomaly are also indicative of a tectonically active region. Scientists have so far failed to explain the deformation of this region in a coherent and predictable picture, such as in California, and this has hampered their ability to assess seismic and tsunami hazards in the region. The NE corner of the Caribbean is unique among the seismically-active regions of the United States in that it is mostly covered by water. This fact presents an additional challenge for seismic and tsunami hazard assessment and mitigation.</p><p>The workshop, convened in San Juan on March 23-24, 1999, was \"historic\" in that it brought together for the first time a broad spectrum of scientists, engineers, and public and private sector officials who deal with such diverse questions as tectonic models, probabilistic assessment of seismic hazard, prediction of tsunami runup, strong ground motion, building codes, stability of man-made structures, and the public’s preparedness for natural disasters. It was an opportunity for all the participants to find out how their own activity fit into the broad picture of science and how it aids society in hazard assessment and mitigation. In addition, the workshop was offered as a continuing education course at the Colegio de Ingenieros y Agrimensores de Puerto Rico, which assured a rapid dissemination of the results to the local community. A news conference which took place during the workshop alerted the public to the efforts of the USGS, other Federal agencies, the Commonwealth of Puerto Rico, universities and the private sector.</p><div><p>During the first day of the workshop, participants from universities, federal institutions, and consulting firms in Puerto Rico, the Virgin Islands, the continental U.S., Dominican Republic, and Europe reviewed the present<span>&nbsp;</span><a href=\"https://pubs.usgs.gov/of/1999/of99-353/stateknowledge.html\" data-mce-href=\"https://pubs.usgs.gov/of/1999/of99-353/stateknowledge.html\">state of knowledge</a><span>&nbsp;</span>including a review and discussion of present plate models, recent GPS and seismic reflection data, seismicity, paleoseismology, and tsunamis. The state of earthquake/tsunami studies in Puerto Rico was presented by several faculty members from the University of Puerto Rico at Mayaguez. A preliminary seismic hazard map was presented by the USGS and previous hazard maps and economic loss assessments were considered. During the second day, the participants divided into working groups and prepared specific recommendations for future activities in the region along the six following topics below. Highlights of these recommended activities are:</p><p><a href=\"https://pubs.usgs.gov/of/1999/of99-353/geophysicsgrp.html\" data-mce-href=\"https://pubs.usgs.gov/of/1999/of99-353/geophysicsgrp.html\">Marine geology and geophysics</a><span>&nbsp;</span>– Acquire deep-penetration seismic reflection and refraction data, deploy temporary ocean bottom seismometer arrays to record earthquakes, collect high-resolution multibeam bathymetry and side scan sonar data of the region, and in particular, the near shore region, and conduct focussed high-resolution seismic studies around faults. Determine slip rates of specific offshore faults. Assemble a GIS database for available marine geological and geophysical data.</p><p><a href=\"https://pubs.usgs.gov/of/1999/of99-353/paleogrp.html\" data-mce-href=\"https://pubs.usgs.gov/of/1999/of99-353/paleogrp.html\">Paleoseismology and active faults</a><span>&nbsp;</span>- Field reconnaissance aimed at identifying Quaternary faults and determining their paleoseismic chronology and slip rates, as well as identifying and dating paleoliquefaction features from large earthquakes. Quaternary mapping of marine terraces, fluvial terraces and basins, beach ridges, etc., to establish framework for understanding neotectonic deformation of the island. Interpretation of aerial photography to identify possible Quaternary faults.</p><p><a href=\"https://pubs.usgs.gov/of/1999/of99-353/jointgrp.html\" data-mce-href=\"https://pubs.usgs.gov/of/1999/of99-353/jointgrp.html\">Earthquake seismology</a><span>&nbsp;</span>– Determine an empirical seismic attenuation function using observations from local seismic networks and recently-installed broad-band stations. Evaluate existing earthquake catalogs from local networks and regional stations, complete the catalogs. Transcribe the pre-1991 network data from 9-track tape onto more stable archival media. Calibrate instruments of local networks. Use GPS measurement to constrain deformation rates used in seismic-hazard maps.</p><p><a href=\"https://pubs.usgs.gov/of/1999/of99-353/engineering.html\" data-mce-href=\"https://pubs.usgs.gov/of/1999/of99-353/engineering.html\">Engineering</a><span>&nbsp;</span>– Prepare liquefaction susceptibility maps for the urban areas. Update and improve databases for types of site conditions. Collect site effect observations and near-surface geophysical measurements for future local (urban-area) hazard maps. Expand the number of instruments in the strong motion program. Develop fragility curves for Puerto Rico construction types and details, and carry out laboratory testing on selected types of mass-produced construction. Consider tsunami design in shoreline construction projects.</p><p><a href=\"https://pubs.usgs.gov/of/1999/of99-353/tsunamigrp.html\" data-mce-href=\"https://pubs.usgs.gov/of/1999/of99-353/tsunamigrp.html\">Tsunami hazard</a><span>&nbsp;</span>- Extract tsunami observations from archives and develop a Caribbean historical tsunami database. Analyze prehistoric tsunami deposits. Collect accurate, up-to-date, near-shore topography and bathymetry for accurate inundation models. Prepare tsunami flooding and evacuation maps. Establish a Caribbean Tsunami Warning System for Puerto Rico and the Virgin Islands. Evaluate local, regional, national, and global seismic networks and equipment, and their role in a tsunami warning system.</p><p><a href=\"https://pubs.usgs.gov/of/1999/of99-353/societalgrp.html\" data-mce-href=\"https://pubs.usgs.gov/of/1999/of99-353/societalgrp.html\">Societal concerns</a><span>&nbsp;</span>– Prepare warning messages, protocols, and evacuation routes for earthquake, tsunami, and landslide hazards for Puerto Rico and the U.S. Virgin Islands. Advocate enforcement of existing building codes. Prepare non-technical hazard assessment maps for political and educational uses. Raise the awareness of potentially affected populations by presentations at elementary schools, by the production of a tsunami video, and by distribution of earthquake preparedness manuals in newspaper supplements. Promote partnerships at state and federal level for long-term earthquake and tsunami hazard mitigation. This partnership should also include the private sector such as the insurance industry, telecommunication companies, and the engineering community.</p><p><p>The following reports of the various working groups are the cumulative recommendations of the community of scientists, engineers, and public officials, who participated in the workshop.

Existing fields are typified by alternating reservoir and seal rocks in post-Ordovician sandstones and shales on anticlines. Thick Devonian and Silurian shale source rocks, depositionally and erosionally confined to this province, at a minimum have generated 4.1 BBOE known ultimate recoverable reserves (as of 1995, 77% gas, 15% condensate, 8% oil) into dominantly Carboniferous reservoirs with average 20% porosity and 156 md permeability. Major detachment surfaces within the source rocks contributed to the thin-skinned and laterally continuous nature of the deformation. Tertiary foreland burial adequate for significant source maturation coincided with the formation of compressional traps. Further hydrocarbon discovery in the fold and thrust belt is expected. In the foreland basin, higher thermal gradients and variable burial history - combined with the presence of unconformity and onlap wedges - create potential there for stratigraphic traps and pre-Andean, block-fault and forced-fold traps.","language":"ENGLISH","publisher":"Geological Survey (U.S.)","doi":"10.3133/ofr9950C","issn":"0094-9140","usgsCitation":"Lindquist, S.J., 1999, The Santa Cruz - Tarija Province of Central South America: Los Monos - Machareti(!)

One Total Petroleum System and corresponding assessment unit, the North Oman Huqf/`Q'? Haushi(!) Total Petroleum System (201401) and Ghaba-Makarem Combined Structural Assessment Unit (20140101), were identified for the Ghaba Salt Basin Province (2014). In the Fahud Salt Basin Province, however, two overlapping Total Petroleum Systems (TPS) were recognized:  1) the North Oman Huqf ? Shu'aiba(!) TPS (201601); Fahud-Huqf Combined Structural Assessment Unit (20160101), and 2) the Middle Cretaceous Natih(!) TPS (201602); Natih-Fiqa Structural/Stratigraphic Assessment Unit (20160201). The boundary for each Total Petroleum System also defines the boundary of the corresponding assessment unit and includes all trap styles and hydrocarbon producing reservoirs within the petroleum system.  \r\n\r\n     In both the Ghaba and Fahud Salt Basin Provinces, hydrocarbons were generated from several deeply-buried source rocks within the Infracambrian Huqf Supergroup. One general `North Oman Huqf' type oil is dominant in the Fahud Salt Basin. Oils in the Ghaba Salt Basin are linked to at least two distinct Huqf source-rock units based on oil geochemistry: a general North Oman Huqf-type oil source and a more dominant `questionable unidentified-source' or `Q'-type Huqf oil source. These two Huqf-sourced oils are commonly found as admixtures in reservoirs throughout north-central Oman.  \r\n\r\n     Hydrocarbons generated from Huqf sources are produced from a variety of reservoir types and ages ranging from Precambrian to Cretaceous in both the Ghaba and Fahud Salt Basin Provinces. Clastic reservoirs of the Gharif and Al Khlata Formations, Haushi Group (M. Carboniferous to L. Permian), dominate oil production in the Ghaba Salt Basin Province and form the basis for the Huqf/`Q' ? Haushi(!) TPS. In contrast, the Lower Cretaceous Shu'aiba and Middle Cretaceous Natih limestones account for most of the production in the Fahud Salt Basin with about 50 percent of the basin's production from porous, fractured Shu'aiba limestones in Yibal field, thus the name North Oman Huqf ? Shu'aiba(!) TPS. Deep gas is produced mainly from Middle Cambrian to Lower Ordovician clastic reservoirs of the Haima Supergroup. Traps in nearly all hydrocarbon accumulations of these petroleum systems are mainly structural and were formed by one or more mechanisms. These trap-forming mechanisms were mainly periodic halokinesis of the thick Cambrian Ara Salt and consequent folding and faulting from basin loading, rifting, or other major tectonic events, particularly those events forming the Oman Mountains and associated foreland-basin system during the Late Cretaceous and Late Tertiary.  \r\n     Many of the future new-field targets will likely be low-relief, subtle structures, as many of the large structures have been drilled. Oman's recent interest and commitments to liquid natural gas export make deep gas a primary objective in the two North Oman Huqf petroleum systems. New-field exploration of deep gas and exploring deeper targets for gas in existing fields will likely identify a significant gas resource in the next thirty years. Moreover, salt-diapir flank traps in these two North Oman Huqf petroleum systems and salt basin provinces have gone essentially untested and will likely be targeted in the near-future.  \r\n\r\n     The Middle Cretaceous Natih(!) TPS is a small efficient system of the Fahud Salt Basin. Natih source rocks are only mature in the Late Cretaceous/Tertiary foredeep and production is primarily from Natih reservoirs; minor production from the Shu'aiba limestone is documented along fault-dip structures. Most traps are structural and are related to development of the foreland basin and formation of the Oman Mountains.

Vapor-diffusion samplers were used at the two sites during March-April 1998 to identify possible discharge points for contaminants along the shore of Allen Harbor and in two wetland areas near the shore. Results from vapor-diffusion samplers will be used in conjunction with other site information to evaluate proposed ground-water monitoring programs.\r\n\r\n\r\nVolatile organic compounds were detected in 41 of 115 samplers placed along the shoreline at the Allen Harbor Landfill. Trichloroethylene was the principal volatile organic compound detected of eight target compounds. The highest vapor concentration measured exceeded 300,000 parts per billion by volume in an area where TCE was detected in groundwater from nearby monitoring wells. Other chemicals detected in vapor-diffusion samplers included tetrachloroethylene, toluene, and benzene. Concentrations of individual volatile organic compounds were less than 100 parts per billion by volume in most samplers.\r\n\r\n\r\nVolatile organic compounds, principally trichloroethylene, were detected in 7 of 30 samplers placed along the shoreline at Calf Pasture Point; the highest trichloroethylene concentration was 1,900 parts per billion by volume. A trace concentration of tetrachloroethylene was detected in one of the samplers. One of 24 samplers placed in two wetland areas near the shore (suspected discharge areas for ground-water containing volatile organic compounds) detected trichloroethylene at a vapor concentration of 14 parts per billion by volume.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nInformation Services [distributor],","doi":"10.3133/ofr9974","issn":"0094-9140","usgsCitation":"Lyford, F.P., Kliever, J., and Scott, C., 1999, Volatile organic compounds detected in vapor-diffusion samplers placed in sediments along and near the shoreline at Allen Harbor Landfill and Calf Pasture Point, Davisville, Rhode Island, March-April 1998: U.S. Geological Survey Open-File Report 99-74, iv, 9 p. :ill., maps ;28 cm., https://doi.org/10.3133/ofr9974.","productDescription":"iv, 9 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":1781,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/ofr99-074/","linkFileType":{"id":5,"text":"html"}},{"id":157469,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a54e4b07f02db62bcaa","contributors":{"authors":[{"text":"Lyford, F.

The first-arrival travel times from these profiles are reported in the hope that they can be used for three-dimensional velocity models in the San Francisco Bay area, particularly for the Livermore Valley and Santa Cruz Mountains.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr99146","usgsCitation":"Williams, A.J., Brocher, T.M., Mooney, W.D., and Boken, A., 1999, Data report for seismic refraction surveys conducted from 1980 to 1982 in the Livermore Valley and the Santa Cruz Mountains, California: U.S. Geological Survey Open-File Report 99-146, 61 p., https://doi.org/10.3133/ofr99146.","productDescription":"61 p.","numberOfPages":"79","temporalStart":"1980-01-01","temporalEnd":"1982-12-31","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":51245,"rank":3,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1999/0146/pdf/of99-146.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":154807,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1999/0146/report-thumb.jpg"},{"id":1161,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1999/0146/","linkFileType":{"id":5,"text":"html"}},{"id":411920,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_16295.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"California","otherGeospatial":"Livermore Valley, Santa Cruz Mountains","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -122.25,\n              37.5\n            ],\n            [\n              -122.25,\n              38\n            ],\n            [\n              -121.25,\n              38\n            ],\n            [\n              -121.25,\n              37.5\n            ],\n            [\n              -122.25,\n              37.5\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd53cce4b0b290850f55c6","contributors":{"authors":[{"text":"Williams, Angela J.","contributorId":36008,"corporation":false,"usgs":true,"family":"Williams","given":"Angela","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":185399,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Brocher, Thomas M. 0000-0002-9740-839X brocher@usgs.gov","orcid":"https://orcid.org/0000-0002-9740-839X","contributorId":262,"corporation":false,"usgs":true,"family":"Brocher","given":"Thomas","email":"brocher@usgs.gov","middleInitial":"M.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":185397,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mooney, Walter D. 0000-0002-5310-3631 mooney@usgs.gov","orcid":"https://orcid.org/0000-0002-5310-3631","contributorId":3194,"corporation":false,"usgs":true,"family":"Mooney","given":"Walter","email":"mooney@usgs.gov","middleInitial":"D.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":185398,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Boken, Annette","contributorId":61703,"corporation":false,"usgs":true,"family":"Boken","given":"Annette","email":"","affiliations":[],"preferred":false,"id":185400,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}
