The findings were to be submitted for inclusion in an Environmental Impact Statement being assembled by Land Management Services of Jackson, Wyoming. The study area is being considered for possible drilling sites in the near future.</p><p>The project area lies on the southwest slope of the Gros Ventre Mountain Range in the Cache Creek-Little Granite Creek area in Teton County, north-western Wyoming. A total of 16 prehistoric sites and isolated finds were recorded within or immediately adjacent to the study area boundaries. The total surface area covered amounted to 1857 acres (or 5.7%) of the 32,580 acres included in the study. An intensive surface evaluation was completed of all staked projects (well locations and access roads) in the survey area. Exploratory or evaluative testing is recommended for the Getty Reserve well location and in one area on the NCRA well access route. Some form of further evaluation is recommended at thirteen other localities.</p><p>Fieldwork was conducted during September, 1980, by archeologists from Archeological Services. Subsequent analysis included the application of a model of site predictability based on the statistical analysis of environmental factors, such as slope, aspect, vegetation, soils, fauna and proximity to water.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr81852","usgsCitation":"Caraveo, C.F., and Lau, S., 1981, An archeological sample survey in the Cache

These rocks have been cut by a wide variety of plutonic and dike rocks including gabbro, diorite, granodiorite, diabase, rhyolite, and granite. \r\n\r\nThe zone containing the sulfide lenses is nearly 16 km long and is cut off by granitic rocks at both the northern and southern ends. The lenses are as much as 200 m thick; one can be traced along strike for more than 4 km. The lenses consist mostly of iron sulfides. Pyrite is the principal sulfide mineral; near intrusive bodies the pyrite has been partially converted to pyrrhotite and locally mobilized into fractures. The sulfides have been oxidized to a depth of about 25 m.\r\n\r\nPreliminary calculations indicate that about 107,500,000 tons of sulfides, averaging 40 percent iron and 35 percent sulfur, are available to a depth of i00 m. Small amounts of nickel, cobalt, zinc, and copper are also present, but at metal prices prevailing in early 1981, these do not constitute significant resources.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr82176","usgsCitation":"Roberts, R.J., Rossman, D.L., Bagdady, A., Conway, C.M., and Helaby, A., 1981, Iron sulfide deposits at Wadi Wassat, Kingdom of Saudi Arabia: U.S. Geological Survey Open-File Report 82-176, v, 133 p. :ill., maps (1 col.) ;28 cm., https://doi.org/10.3133/ofr82176.","productDescription":"v, 133 p. :ill., maps (1 col.) ;28 cm.","costCenters":[],"links":[{"id":140104,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0176/report-thumb.jpg"},{"id":34643,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0176/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":34644,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0176/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aa7e4b07f02db666bb6","contributors":{"authors":[{"text":"Roberts, R.

The area includes 4,423 square miles in the Kentucky, Licking, and Red River basins. Coal-bearing rocks of Pennsylvanian age underlie most of the area. Coal production in 1978 was about 38 million tons, 65% of which was from surface mining. The drainage from the mined areas contains large amounts of dissolved solids. Sulfate, manganese, and iron concentrations in most of the area streams exceed background levels, with the higher concentrations in streams draining the headwaters of the North and Middle Forks of the Kentucky River. The pH of most of the streams is near neutral acid-mine drainage being partially neutralized close to its source. Ground waters in the upper 300 feet of the aquifers are generally suitable for most purposes, although dissolved iron is generally high. Below 300 feet, the water is saline. Yields to wells range from 1 to 325 gallons per minute.

This feature is very unusual and an attempt has been made to determine if the recording is real or spurious. As the pumping station is a small heavily constructed bunker type of structure located on material of low shear wave velocity it was considered likely that soil-structure interaction might be responsible for the 2 Hz component. However, both an experimental and theoretical investigation fail to establish this. This report describes the theoretical investigation. The experimental investigation is described in a separate open-file report.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr82317","usgsCitation":"Bycroft, G., 1981, Anomalous record of October 15, 1979, Imperial Valley, California, earthquake from Coachella Canal Engine House No. 4: U.S. Geological Survey Open-File Report 82-317, 14 p., ill. ;28 cm., https://doi.org/10.3133/ofr82317.","productDescription":"14 p., ill. ;28 cm.","costCenters":[],"links":[{"id":142108,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0317/report-thumb.jpg"},{"id":35735,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0317/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac7e4b07f02db67b619","contributors":{"authors":[{"text":"Bycroft, G.N.","contributorId":106903,"corporation":false,"usgs":true,"family":"Bycroft","given":"G.N.","email":"","affiliations":[],"preferred":false,"id":157200,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Seven hundred and twenty-eight samples in 25 measured sections were collected along trenches and pits 2.5 m in depth and 2,600 m in total length. Alluvium was thicker than the excavation depth along about 50 percent of the trench length. The average gold content was 4.4 mg per m3, and the highest grade trench contained 40 mg gold per m 3. Because fine particulate gold is rare in the alluvium, a few large particles, 1 to 5 mm in diameter, greatly affected the sampling results. The ancient placer diggings are in small headwater wadis distributed over a 30-km 2 area, and the total dug area is about 1.2 km2. The placer produced an estimated 50 kg of gold and was worked about 2,600 + 250 years ago. The potential for a present-day placer operation is small. \r\n\r\nThe gold is sparsely distributed in locally derived, flood-deposited, immature gravels throughout a stratigraphic section that consists of 1) calichified, saprolitic bedrock of Precambrian age; 2) basal, intensely calichified, saprolitic gravel (0-3 m thick) of Pleistocene age; 3) disconformable, slightly consolidated gravel and sand (0-1 m thick) of late Pleistocene age containing sparse, disseminated caliche; 4) firm loessic silt (0-1 m thick) of early Holocene age; and 5) loose sand and gravel (0.3-1 m thick) of late Holocene age. The loessic silt accumulated during the Holocene pluvial. The top of the loessic silt unit is dated at about 6,000 years B.P. by using charcoal from hearths of ancient man. Following the Holocene pluvial, the climate became arid, and extreme desiccation resulted in abundant eolian sand that progressively diluted the late Holocene gravels. The remnants of the pre-Holocene stratigraphy suggest similar climatic cycles during the Pleistocene.\r\n\r\nAbundant, sparsely mineralized, gold-bearing quartz veins (0-1 m wide) were the source of the placer gold. These late Proterozoic veins have hydrothermally altered wall-rock zones (1-5 m wide). The veins are dispersed over an area of 50 km 2. Though many veins were prospected in ancient times and some were slightly worked, only the Mokhyat ancient mine, located on a quartz-vein zone 30 m wide by 200 m long, was extensively worked. The quartz contains chalcopyrite, galena, sphalerite, tetrahedrite, an unidentified bismuth mineral, and small amounts of dispersed gold. \r\n\r\nThe fissure quartz veins lie at the complexly splayed, terminal end of a small northwest-trending Najd fault that elsewhere along strike has ii km of left-lateral displacement. Most large veins are in north-trending vertical fractures where the stresses were distributed along an older, north-trending structural grain in andesitic greenstone terrane. Subhorizontal fracture sets contain conspicuous, well-developed gold-bearing quartz veins and associated alteration zones. These attest to the shallowness and youthfulness of mineralization during latest Precambrian time.\r\n\r\nLate Precambrian granitic plutons (625-600 m.y. old) had been deeply eroded before the gold minerals were emplaced; hence, the gold is not related to granitic plutonism. Abundant, widely distributed diabasic dikes associated with the Najd faulting event of latest Precambrian age were probably the heat source for the hydrothermal convection system and possibly the source of the gold.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr82414","usgsCitation":"Schmidt, D.L., Puffett, W., Campbell, W.L., and Al-Koulak, Z., 1981, Gold placer and Quaternary stratigraphy of the Jabal Mokhyat area, southern Najd Province, Kingdom of Saudi Arabia: U.S. Geological Survey Open-File Report 82-414, 76 p. :ill., maps ;28 cm., https://doi.org/10.3133/ofr82414.","productDescription":"76 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":140817,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0414/report-thumb.jpg"},{"id":34606,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0414/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":34607,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0414/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":34608,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0414/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abde4b07f02db674032","contributors":{"authors":[{"text":"Schmidt, D.

These clear objectives are, therefore, those of the research program, not the economics of operations, which are of concern to industry.</p><p>The Program is a contract research program and is an integral part of the Conservation Division. It is a focal point for deriving possible solutions from the university community, private industry, and the Federal laboratory system for identified offshore operational problems. This vast interdisciplinary body of science and technology provides the kind of research needed by the Division in its Outer Continental Shelf (OCS) operations which involve such problematic areas as structural dynamics, fluid flow, and geotechnology.</p><p>The Program encourages innovation and creativity which can be accomplished only by talented scientists and engineers who are dedicated to man's endeavor to make breakthroughs in science and technology.</p><p>Because the Division's mission is operational, in a sense like the U.S. Navy, the R&amp;D Program must progress in a timely manner even though technological advances cannot really be scheduled. As the Navy's Office of Naval Research (ONR) has so successfully coped with the seeming dichotomy of anticipating the occurrence of innovations, so must the Conservation Division. Thus, USGS, like ONR, makes use of the unsolicited proposal and the best effort contract to accomplish its objectives. Good science and technology can only be accomplished when several variables converge: a talented investigator doing his own research, which happens to coincide with our needs, availability of resources, time scales, etc. Our task is to \"beat the bushes\" so that these people come to us with their innovative ideas and concepts.

The proposed network , consisting of 92 wells, is designed to monitor changes in storage and quality of ground water resulting from climatic changes and management-induced stresses. In the proposed network , water levels in all wells would be measured semiannually, in April and September, and monthly in a few key wells. The water-level measurements would provide data that could be used to determine changes in ground-water storage. In addition to the currently monitored characteristics--temperature, specific conductance, pH, and chloride ion concentration--inclusion of annual sampling and analysis for major ions and nutrients is proposed. The network would also include sampling and analysis for trace elements once every 4 years. More frequent analyses are proposed in areas where water-quality problems are known to exist or where potential water-quality problems are recognized. Analyses for major ions, nutrients, and trace elements are included in the proposed network to provide baseline data for monitoring long-term changes in water quality and to detect any unexpected changes in quality.
