As part of a program undertaken cooperatively by the Liberian Geological Survey (LGS) and the U. S. Geological Survey (USGS), under the sponsorship of the Government of Liberia and the Agency for International Development, U. S. Department of State, Liberia was mapped by geologic and geophysical methods during the period 1965 to 1972. The resulting geologic and geophysical maps are published in ten folios, each covering one quadrangle (see index map). The first systematic mapping in the Harper quadrangle was by Baker, S. P. Srivastava, and W. E. Stewart (LGS) at a scale of 1:500,000 in the vicinity of Harper in the southeastern, and of Karloke in the northeastern part of the quadrangle in 1960-61. Brock and Chidester carried out systematic mapping of the quadrangle at a scale of 1:250,000 in the period September 1971-May 1972; the geologic map was compiled from field data gathered by project geologists and private companies as indicated in the source diagram, photogeologic maps, interpretation of airborne magnetic and radiometric surveys, field mapping, and ground-based radiometric surveys in which hand-held scintillators were used. R. W. Bromery, C. S. Wotorson, and J. C. Behrendt contributed to the interpretation of geophysical data. Total-intensity aeromagnetic and total-count gamma radiation maps (Behrendt and Wotorson, in press a, b), and unpublished data derived from those maps, including the near-surface and the regional magnetic components and aeromagnetic/radiometric correlations, were used in the interpretation.

The work for the first annual, report (Larson, 1974) was financed jointly by the U.S. Bureau of Sport Fisheries and the U.S. Geological Survey.
Continuous recorders were used to monitor water levels in Devils Hole, two observation wells, and the flow from four springs. Also, monthly readings were made on two wells to help define a general trend of ground-water levels. Also, monthly meter readings of six electrically powered irrigation wells provided a record of power consumption, which in turn is a measure of the amount of water pumped.
The purpose of the work is to observe the effects of groundwater withdrawals for irrigation on the level in Devils Hole and the flow from the major springs in the area. The pool in Devis Hole, which is a collapsed fault structure, is the only known native habitat of desert pupfish, Cyprinodon diabolis.

Calculations for a typical geothermal well show the effects on production of varying the system parameters of aquifer permeability, depth to water table, and base temperature. Field data from Wairakei, New Zealand, demonstrate the reductions in flow caused by mineral deposits in the bore. Data from Imperial Valley, Calif., agree well with calculated results.

The study area, near Enola, Pa., consists of five adjacent drainage basins, four of which will be crossed by Interstate 81. Ninety percent of the land in each of the basins is in forest or grass. Active farmland accounts for less than 10 percent, and the remainder is in roadways and buildings. The major factor affecting sediment concentrations and discharges was the construction of a one-lane roadway and a 5-acre (2 hm2) farm pond in basin 2. Approximately 100 tons (90 t) of sediment was discharged by the stream as a result of the roadway and pond construction.

Nimba Concession Area. Mapping has been done by company geologists since 1955 and summarized by Berge (1966, 1968, 1973, 1974). Detailed mapping has been done in many areas underlain by iron deposits, but the concession area as a whole has been mapped only by reconnaissance methods. For both compilers, photogeologic mapping and the interpretation of air-borne magnetic and radiometric surveys (Behrendt and Wotorson, 1974, a and b) are integral to the interpretation as shown.

Before development of Walt Disney World began (mid-1967), all of this tract of land was scrubby flatlands and swamp. Walt Disney World facilities now (1974) occupy slightly less than 10 percent of the area. Hydrologic data are available for most of the area for the 6-year period July 1967-June 1973, with some records starting before July 1967.
The potentiometric surface of the Floridan aquifer near Bay Lake has declined 8 feet (2 metres) on the average. Seventy-five percent of the decline is attributed to water use in the RCID; the remaining decline is attributed to deficient rainfall since the records began in March 1966. The discharge of streams in the RCID has apparently increased. However, the hydrologic conditions were changing locally as the development of the area progressed. Because of this change, the magnitude and seasonal distribution of any eventual change in streamflow cannot be accurately appraised until additional data are obtained after the development has stabilized. Some changes in water quality have occurred, but none can be attributed to urbanization.

Ten core samples of two rich oil-shale beds from the Parachute Creek Member of the Eocene Green River Formation, Piceance Creek basin, Colorado, and Uinta Basin, Utah, were analyzed for 34 major, minor, and trace elements. For 23 of these elements, principal mineralogical residence is established or suggested. Such studies of distribution and mineralogical residence provide important data for predicting the kinds and amounts of elements and compounds--some possibly harmful-that might he released into the environment by oil-shale mining operations. However, because of the many variables involved, no attempt is made to discuss these results in terms of any of the various retorting methods.

1:250,000) into which Alaska has been divided for topographic mapping (p. 2). This index does not include reports that deal only with administrative matters or that were placed in open files but not formally published.
Reports that deal with Alaska as a whole, with areas that cannot be identified with any specific quadrangle, or with offshore areas that are not within quadrangle boundaries, or that consist mainly of statistical data on the quality or quantity of water are listed under ALASKA - GENERAL, as are bibliographies, indexes, and similar publications. The ALASKA - GENERAL list appears before the alphabetically arranged quadrangle listings.

1:250,000) into which Alaska has been divided for topographic mapping (p. 3). This index does not include reports that deal only with administrative matters or that were placed in open files but not formally published.
Reports that deal with Alaska as a whole, with areas that can not be identified with any specific quadrangle, or with offshore areas that are not within quadrangle boundaries, or that consist mainly of statistical data on the quality or quantity of water are listed under ALASKAGENERAL, as are bibliographies, indexes, and similar publications. The ALASKA - GENERAL list appears before the alphabetically arranged quadrangle listings.

essentially raw data. These reports and maps are available to the public and may be consulted at various Geological Survey and state offices. Essentially complete files of reports and maps on Alaska are maintained at Geological Survey Public Inquiries Offices in Anchorage, Alaska, San Francisco and Los Angeles, California, Denver, Colorado, and Spokane, Washington; at Geological Survey Libraries in Washington, D. C., Denver, Colorado, and Menlo Park, California; at Geological Survey Alaskan Geology Branch offices in College, Alaska, and Menlo Park, California; at Geological Survey Water Resources Division office in Juneau, Alaska; and at State of Alaska Division of Geological and Geophysical Surveys offices in Anchorage, College, and Juneau, Alaska. Reproducible material from which copies of most of the reports and maps may be made at private expense are available in the Technical Data Unit, Alaskan Geology Branch, U.S. Geological Survey, 345 Middlefield Road, Menlo Park, California 94025.

stress orientation at the Nevada Test Site","docAbstract":"A tectonic synthesis of the NTS (Nevada Test Site) region, when combined with seismic data and a few stress and strain measurements, suggests a tentative model for stress orientation. This model proposes that the NTS is undergoing extension in a N. 50 ? W.-S. 50 ? E. direction coincident with the minimum principal stress direction. The model is supported by (1) a tectonic similarity between a belt of NTS Quaternary faulting and part of the Nevada-California seismic belt, for which northwest-southeast extension has been suggested; (2) historic northeast- trending natural- and explosion-produced fractures in the NTS; (3) the virtual absence in the NTS of northwest-trending Quaternary faults; (4) the character of north-trending faults and basin configuration in the Yucca Flat area, which suggest a component of right-lateral displacement and post-10 m.y.

In the Walker Lane of western Nevada, crystallization of plutons associated with Miocene volcanism may have increased the competency and thickness of the crust and its ability to propagate stress, thereby modulating the frequency (spacing) of basin-range faults.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr74176","usgsCitation":"Carr, W.J., 1974, Summary of tectonic and structural evidence for stress orientation at the Nevada Test Site: U.S. Geological Survey Open-File Report 74-176, iv, 53 leaves, 2 sheets :ill., maps (some folded) ;27 cm., https://doi.org/10.3133/ofr74176.","productDescription":"iv, 53 leaves, 2 sheets :ill., maps (some folded) ;27 cm.","costCenters":[],"links":[{"id":146966,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1974/0176/report-thumb.jpg"},{"id":41355,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1974/0176/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":41356,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1974/0176/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":41357,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1974/0176/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b01e4b07f02db6984ac","contributors":{"authors":[{"text":"Carr, Wilfred James","contributorId":12033,"corporation":false,"usgs":true,"family":"Carr","given":"Wilfred","email":"","middleInitial":"James","affiliations":[],"preferred":false,"id":166957,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":12427,"text":"ofr741003 - 1974 - Statistical summary of geochemical data furnished by 85 laboratories for for six geochemical exploration reference samples","interactions":[],"lastModifiedDate":"2012-02-02T00:06:33","indexId":"ofr741003","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1974","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"74-1003","title":"Statistical summary of geochemical data furnished by 85 laboratories for for six geochemical exploration reference samples","language":"ENGLISH","publisher":"U.S. Geological Survey],","doi":"10.3133/ofr741003","usgsCitation":"Allcott, G., and Lakin, H.W., 1974, Statistical summary of geochemical data furnished by 85 laboratories for for six geochemical exploration reference samples: U.S. Geological Survey Open-File Report 74-1003, 103 p. ;29 cm., https://doi.org/10.3133/ofr741003.","productDescription":"103 p. ;29 cm.","costCenters":[],"links":[{"id":144875,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49dce4b07f02db5e1776","contributors":{"authors":[{"text":"Allcott, G.H.","contributorId":94676,"corporation":false,"usgs":true,"family":"Allcott","given":"G.H.","affiliations":[],"preferred":false,"id":166122,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lakin, H.

The spatial variation is described by the use of sample statistics such as minima, maxima, and means of the variables at each station. The temporal variation is described by using nonparametric statistical testing procedures to assess time trends in the data at each station.
Evaluation of the coefficients (mean, amplitude, phase coefficient] derived by harmonic analysis of available daily stream-temperature records indicates adequate depiction of yearly seasonal variability and provides information relative to spatial variation in stream temperatures at most sites. Lowest harmonic amplitudes, which are indicative of little seasonal variability in stream temperature, were observed in Florida, along the eastern Gulf coast, and along the Pacific coast. Greatest annual variations in stream temperature exists in the Souris, Red (of the North), and Missouri River basins.
Temporal variations in stream temperature denoted by significant changes (at the 99 percent level of confidence) in annual harmonic coefficients were indicated at 15 of 80 stations used in the evaluation. Trends in stream temperature were found to exist at one or more stations in each of the six following areas: the Atlantic coast above Florida; Florida and the eastern Gulf; the Souris River, Red River of the North, and Missouri River basins; the Texas Gulf and Rio Grande area; the Colorado River basin; and the Pacific coast area.
Significant trends (at the 99 percent level of confidence) were found in the long-term streamflow chemical quality record at 15 of 88 stations analyzed. Of these stations, 10 showed an increase in levels of specific conductances while 5- showed a decrease. Trends were indicated for water-quality data from stations located in the following areas: the Atlantic coast above Florida; the Souris River, Red River of the North, and Missouri River basins; the Arkansas and Red River basins; the Texas Gulf and Rio Grande area; the Colorado River basin; and the Pacific coast area.

Predictive modeling, monitoring, and management of radionuclides dissolved and transported by ground water can best be done for sites in relatively simple hydrogeologic settings; namely, in unfaulted relatively flat-lying strata of intermediate permeability such as silt, siltstone and silty sandstone. In contrast, dense fractured or soluble media, and poorly permeable porous media (aquitards) are not suitable for use as burial sites, first because of media heterogeneity and difficulties of sampling, and consequently of predictive modeling, and second, because in humid zones burial trenches in aquitards may overflow. A buffer zone several thousands of feet to perhaps several miles around existing or proposed sites is a mandatory consequence of the site selection criteria. As a specific example, the Maxey Flats, Kentucky low-level waste disposal site is examined.

hazards and land-use planning","docAbstract":"Basic earth-science data are necessary for a realistic assessment of seismic hazards and as a basis for limiting corrective land-use controls only to those areas of greatest hazard. For example, the location, character, and amount of likely displacement and activity of surface faulting can be predicted if detailed geologic maps and seismic data are available and are augmented by field studies at critical localities. Because few structures can withstand displacement of their foundations, they should be located off active fault traces, the distance varying with the character of faulting, the certainty with which fault traces are known, and the importance of the structure. Recreational activities and other nonoccupancy land uses should be considered for fault zone areas where land is under pressure for development; elsewhere, such areas should remain as open space. \r\n\r\nTwo methods of predicting ground shaking effects have applications to land-use decisions: (1) Relative earthquake effects can be related to firmness of the ground and can be used in a gross way to allocate population density in the absence of more sophisticated analyses; and (2) intensity maps, based on, (a) damage from former earthquakes, or (b) a qualitative analyses of geologic units added to a design earthquake, can be helpful both for general and specific plans. Theoretical models are used with caution to predict ground motion for critical structures to be located at specific sites with unique foundation conditions. Fully adequate methods of assessing possible shaking remain to be developed. Where land-use decisions do not reflect likely ground shaking effects, stringent building codes are needed, particularly for important structures. \r\n\r\nGround failure (landsliding, ground cracking and lurching, differential settlement, sand boils, and subsidence) commonly results from liquefaction, loss of soil strength, or compaction. Areas suspected of being most likely to fail should not be developed unless detailed site studies can demonstrate the hazard does not exist or can be overcome. Various methods can be used to reduce the high, long-term public costs that follow development of unstable ground. However, areas subject to tectonic deformation generally cannot be predicted nor can effects of such deformation be minimized. \r\n\r\nLarge water waves, such as produced by tsunamis, seiches, and dam failure or overtopping, can be anticipated in many places. Their effects can be lessened by land-use regulations similar to flood-plain zoning, restrictions on location of critical structures, and appropriate warning systems. \r\n\r\nMany local, state, and federal government agencies, universities, and private consultants may be able to assist planners by advising them of pertinent data and where those data can be obtained. Interpretation of the data for an evaluation of seismic risk commonly requires a team of planners, geologists, and soil and structural engineers.","language":"ENGLISH","publisher":"U.S. Dept. of the Interior, Geological Survey,","doi":"10.3133/cir690","usgsCitation":"Nichols, D.R., and Buchanan-Banks, J.M., 1974, Seismic hazards and land-use planning: U.S. Geological Survey Circular 690, iv, 33 p. :ill. ;27 cm., https://doi.org/10.3133/cir690.","productDescription":"iv, 33 p. :ill. ;27 cm.","costCenters":[],"links":[{"id":124619,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/circ/1974/0690/report-thumb.jpg"},{"id":30637,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/circ/1974/0690/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1ae4b07f02db6a879b","contributors":{"authors":[{"text":"Nichols, Donald R.","contributorId":83129,"corporation":false,"usgs":true,"family":"Nichols","given":"Donald","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":147239,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Buchanan-Banks, Jane M.","contributorId":29421,"corporation":false,"usgs":true,"family":"Buchanan-Banks","given":"Jane","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":147238,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":2673,"text":"wsp2031 - 1974 - Influence of recharge basins on the hydrology of Nassau and Suffolk Counties, Long Island, New York","interactions":[],"lastModifiedDate":"2012-02-02T00:05:25","indexId":"wsp2031","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1974","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":341,"text":"Water Supply Paper","code":"WSP","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"2031","title":"Influence of recharge basins on the hydrology of Nassau and Suffolk Counties, Long Island, New York","docAbstract":"An investigation of recharge basins on Long Island was made by the U.S. Geological Survey in cooperation with the New York State Department of Environmental Conservation, Nassau County Department of Public Works, Suffolk County Department of Environmental Control, and Suffolk County Water Authority. The major objectives of the study were to (1) catalog basic physical data on the recharge basins in use on Long Island, (2) measure quality and quantity of precipitation and inflow, (3) measure infiltration rates at selected recharge basins, and (4) evaluate regional effects of recharge basins on the hydrologic system of Long Island. The area of study consists of Nassau and Suffolk Counties -- about 1,370 square miles -- in eastern Long Island, N.Y. \r\n\r\nRecharge basins, numbering more than 2,100 on Long Island in 1969, are open pits in moderately to highly permeable sand and gravel deposits. These pits are used to dispose of storm runoff from residential, industrial, and commercial areas, and from highways, by infiltration of the water through the bottom and sides of the basins. \r\n\r\nThe hydrology of three recharge basins on Long Island -- Westbury, Syosset, and Deer Park basins -- was studied. The precipitation-inflow relation showed that the average percentages of precipitation flowing into each basin were roughly equivalent to the average percentages of impervious areas in the total drainage areas of the basins. Average percentages of precipitation flowing into the basins as direct runoff were 12 percent at the Westbury basin, 10 percent at the Syosset basin, and 7 percent at the Deer Park basin. Numerous open-bottomed storm-water catch basins at Syosset and Deer Park reduced the proportion of inflow to those basins, as compared with the Westbury basin, which has only a few open-bottomed catch basins. \r\n\r\nInflow hydrographs for each basin typify the usual urban runoff hydrograph -- steeply rising and falling limbs, sharp peaks, and short time bases. Unit hydrographs for the Westbury and the Syosset basins are not expected to change; however, the unit hydrograph for the Deer Park basin is expected to broaden somewhat as a result of additional future house construction within the drainage area. \r\n\r\nInfiltration rates averaged 0.9 fph (feet per hour) for 63 storms between July 1967 and May 1970 at the Westbury recharge basin, 0.8 fph for 22 storms from July 1969 to September 1970 at the Syosset recharge basin, and 0.2 fph for 24 storms from March to September 1970 at the Deer Park recharge basin. Low infiltration rates at Deer Park resulted mainly from (1) a high percentage of eroded silt, clay, and organic debris washed in from construction sites in the drainage area, which partly filled the interstices of the natural deposits, and (2) a lack of a well-developed plant-root system on the floor of the younger basin, which would have kept the soil zone more permeable. \r\n\r\nThe apparent rate of movement of storm water through the unsaturated zone below each basin averaged 5.5 fph at Westbury, 3.7 fph at Syosset, and 3.1 fph at Deer Park. The rates of movement for storms during the warm months (April through October) were slightly higher than average, probably because the recharging water was warmer than it was during the rest of the year, and therefore, was slightly less viscous.\r\n\r\nOn the average, a 1-inch rainfall resulted in a peak rise of the water table directly below each basin of 0.5 foot; a 2-inch rainfall resulted in a peak rise of about 2 feet. The mound commonly dissipated within 1 to 4 days at Westbury, 7 days to more than 15 days at Syosset, and 1 to 3 days at Deer Park, depending on the magnitude of the peak buildup. \r\n\r\nAverage annual ground-water recharge was estimated to be 6.4 acre-feet at the Westbury recharge basin, 10.3 acre-feet at the Syosset recharge basin, and 29.6 acre-feet at the Deer Park recharge basin. \r\n\r\nChemical composition of precipitation at Westbury, Syosset, and Deer Park drainage areas was similar: ","language":"ENGLISH","publisher":"U.S. Govt.
