On the Precambrian Arabian Shield, local positive gravity anomalies are associated with greenstone belts, gneiss domes, and the Najd fault zones. Local negative gravity anomalies correlate with granitic plutonic rocks. A steep gravity gradient of as much as 4 mgal-km-1 marks the continental margin on the coastal plain near the southwestern end of the strip. Bouguer gravity anomaly values range from -10 to +40 mgal southwest of this gradient and from -170 to -100 mgal in a 300-km-wide gravity minimum northeast of the gradient. Farther northeast, the minimum is terminated by a regional gradient of about 0.1 mgal-km-1 that increases toward the Arabian Gulf. The regional gravity anomaly pattern has been modeled by using seismic refraction and Raleigh wave studies, heat-flow measurements, and isostatic considerations as constraints. The model is consistent with the hypothesis of upwelling of hot mantle material beneath the Red Sea and lateral mantle flow beneath the Arabian plate. The model yields best-fitting average crustal densities of 2.80 g-cm-3 (0-20 km depth) and 3.00 g-cm-3 (20-40 km depth) southwest of the Nabitah suture zone and 2.74 g-cm-3 (0-20 km depth) and 2.94 g-cm-3 (20-40 km depth) northeast of the suture zone. The gravity model requires that the crust be about 20 km thick at the continental margin and that the lower crust between the margin and Bishah (lat 20? N., long 42.5? E.) be somewhat denser than the lower crust to the northeast. \r\n\r\nDetailed correlations between 1:250,000- and 1:500,000-scale geologic maps and the gravity anomaly map suggest that the greenstone belts associated with gravity highs contain a large proportion of gabbroic and dioritic intrusive rocks and that the bulk density of the upper crust associated with some of the batholithic complexes has been lowered by the large-scale intrusion of granitic material at depth, as well as by that exposed at the surface.\r\n\r\nA comparison of known base and precious metals occurrences with the Bouguer gravity anomaly field shows, in some cases, a correlation between such occurrences and the features of the gravity anomaly map. Several areas were identified between known mineral occurrences along gravity-defined structures that may contain mineral deposits if the lithologic environment is favorable.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr83789","usgsCitation":"Gettings, M.E., 1983, A simple Bouguer gravity anomaly map of southwestern Saudi Arabia and an initial interpretation: U.S. Geological Survey Open-File Report 83-789, iii, 93 p. :maps ;28 cm., https://doi.org/10.3133/ofr83789.","productDescription":"iii, 93 p. :maps ;28 cm.","costCenters":[],"links":[{"id":141864,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1983/0789/report-thumb.jpg"},{"id":36732,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1983/0789/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":36733,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1983/0789/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":36734,"rank":402,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1983/0789/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":36735,"rank":403,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1983/0789/plate-4.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":36736,"rank":404,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1983/0789/plate-5.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":36737,"rank":405,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1983/0789/plate-6.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":36738,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1983/0789/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b17e4b07f02db6a64c9","contributors":{"authors":[{"text":"Gettings, M.

The purpose of the study would be to provide information to basin planners and regulators on the quantity, quality, and use of water to guide management decisions regarding basin development. Water quality and quantity problems in the Sangamon River basin are associated primarily with agricultural and urban activities, which have contributed high concentrations of suspended sediment, nitrogen, phosphorus, and organic matter to the streams. The impact has resulted in eutrophic lakes, diminished capacity of lakes to store water, low concentrations of dissolved oxygen, and turbid stream and lake waters. The four elements of the plan of study include: (1) determining suspended sediment and nutrient transport, (2) determining the distribution of selected inorganic and organic residues in streambed sediments, (3) determining the waste-load assimilative capacity of the Sangamon River, and (4) applying a hydraulic model to high streamflows.

Alluvial aquifers of small areal extent are present in valley-fill deposits of six major drainages. Consolidated-rock aquifers include the bird's-nest aquifer in the Parachute Creek Member of the Green River Formation, which is limited to the central part of the study area; and the Douglas Creek aquifer, which includes parts of the Douglas Creek Member of the Green River Formation and parts of the intertonguing Renegade Tongue of the Wasatch Formation; this aquifer underlies most of the study area. </span></p><p><span>The alluvial aquifers are recharged by infiltration of streamflow and leakage from consolidated-rock aquifers. Recharge is estimated to average about 32,000 acre-feet per year. Discharge from alluvial aquifers, primarily by evapotranspiration, also averages about 32,000 acre-feet per year. The estimated volume of recoverable water in storage in alluvial aquifers is about 200,000 acre-feet.

Systematic Crone electromagnetic and self-potential surveys indicate that weakly conductive tabular bodies having a weak to moderate self-potential effect extend downdip from two discontinuously exposed, parallel ridges of mineralized quartzite. Crone electromagnetic data were quantitatively interpreted using characteristic parameter lines adapted for use at 1830 and 5010 Hz, the frequencies employed at Umm ar Rummf. Depths to the top of the conductors were computed to be from 20 to 40 m or about the thickness of the oxidized zone, which behaves as a variably conductive overburden. Both tabular conductors can also be traced geophysically to the north and south of the copper-bearing outcrops. The association of the geophysical anomalies with copper-mineralized rocks has been proved by drilling. \r\n\r\nReconnaissance MAXMIN electromagnetic profiles across the target using a wide coil separation show broad, low-amplitude anomalies that may indicate mineralized rocks at depth, and reconnaissance ground-magnetic profiles show strong total-field intensity anomalies associated with basaltic dikes of probable Tertiary age.

Although a previous, airborne electromagnetic survey found no anomalies in the vicinity of the ancient mines in the region, surface indications of anomalous copper and zinc at both Dhahar and Al Hajrah are abundant. \r\n\r\nReconnaissance Crone electromagnetic traverses across the Dhahar prospect area delineated numerous conductive zones, but none had a dip-angle anomaly of more than 10?. Similar results were obtained at Al Hajrah. \r\n\r\nWith one or two encouraging exceptions, self-potential surveys at Al Hajrah showed only broad gradients and anomalies having amplitudes of less than 40 mV. Dipole-dipole induced polarization surveys at Al Hajrah delineated two nearly continuous polarizable zones having an aggregate strike length of almost 7 km. The two zones are symmetrically disposed on either side of a median aplitic dike and may lie on opposing limbs of a south-plunging antiform. Chargeabilities in the anomalous zones are weak to moderate but in most places are clearly associated with anomalous copper and (or) zinc concentrations found by surface sampling. \r\n\r\nGround electromagnetic traverses are recommended to determine the most conductive intervals of anomalous induced polarization effect in the anomalous zones; these conductive intervals should then be tested by drilling, where appropriate.

This Jurassic intrusion displays large and systematic chemical and mineralogical zonation over a horizontal distance of 5 km. Major-element variations compare closely with Dalyls average andesite-dacite-rhyolite over an SiO2 range of 63 to 76 percent. \r\n\r\nFor various reasons it was originally thought that assimilation played a dominant role in development of the Snake Creek-Williams Canyon pluton. However, based on modeling of more recently obtained trace element and isotopic data, we have concluded that the zonation is the result of in-situ fractional crystallization, with little assimilation at the level of crystallization. \r\n\r\nThis report summarizes data available for each of the mineral species present in the zoned intrusion. Special attention has been paid to trends We present oxygen and strontium isotopic data for olivine tholeiites, evolved (that is, differentiated and (or) contaminated) lavas, rhyolites, and crustal- derived xenoliths from the Snake River Plain. These data show that the olivine tholeiites are fairly uniform in d80 (5.1 to 6.2) and 87Sr/86Sr (0.7056 to 0.7076) and reveal no correlation between these ratios. The tholeiites are considered representative of mantle-derived magmas that have not interacted significantly with crustal material or meteoric water. The evolved lavas display a wider range in d 80 (5.6 to 7.6) and 87Sr/86Sr (0.708 to 0.717) with positive correlations between these ratios in some suites but not in others. Crustal xenoliths have high and variable 8?Sr/86Sr (0.715 to 0.830) and d80 values that vary widely (6.7 to 9.2) and are a few permil greater than d80 values of the Snake River basalts. Thus, isotopic data for the evolved lavas are permissive of small degrees of contamination by crustal rocks similar to the most d80-depleted xenoliths. The d80 enrichments in some evolved lavas also are consistent with crystal fractionation processes and do not necessarily require bulk interaction with crustal rocks. Enrichment in d80 but not in 87Sr/86Sr in one suite of evolved lavas suggests that crustal contamination may not be essential to the petrogenesis of those lavas. Other suites of evolved lavas display large variations in 87Sr/86Sr that reflect at least some selective contamination with 87St. \r\n\r\nBulk solid/liquid oxygen-isotope fractionation factors (a's) calculated for the evolved lavas from Craters of the Moon National Monument are comparatively large. These a's are dependent upon the nature and proportions of phases removed by crystal fractionation; basaltic lava a's differ from latitic lava a?s in accordance with different phenocryst assemblages in these rocks. \r\n\r\nSnake River Plain rhyolites are isotopically distinct from both the analyzed crustal xenoliths and olivine tholeiites. Their origin remains poorly understood, but crustal or sub-crustal sources may be viable. In the first case, they must be derived by anatexis of material distinct from the analyzed crustal xenoliths. In the second case, they must be derived from material unlike the source for tholeiites. No cogenetic relation with the tholeiites seems likely on the basis of available data. that might relate to the variation in the chemical petrology of the pluton.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr83338","usgsCitation":"Leeman, W.P., and Whelan, J.F., 1983, Oxygen and strontium isotopic studies of basaltic lavas from the Snake River plain, Idaho: U.S. Geological Survey Open-File Report 83-338, 35 p. ill. ;28 cm., https://doi.org/10.3133/ofr83338.","productDescription":"35 p. ill. ;28 cm.","costCenters":[],"links":[{"id":143338,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1983/0338/report-thumb.jpg"},{"id":37775,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1983/0338/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae4e4b07f02db68a0dd","contributors":{"authors":[{"text":"Leeman, William P.","contributorId":87142,"corporation":false,"usgs":true,"family":"Leeman","given":"William","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":160600,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Whelan, Joseph F.","contributorId":29792,"corporation":false,"usgs":true,"family":"Whelan","given":"Joseph","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":160599,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Using a mass-balance model, the writer calculated P loadings from present-day P concentrations measured in lake water and from other easily measured physical characteristics in a total of 28 lakes in drainage basins that contain only forest and residential land. The loadings from background sources (forest-land drainage and bulk precipitation) to each of the lakes were estimated by methods developed in a previous study. Differences between estimated present-day P loadings and loadings from background sources were attributed to changes in land use. The mean increase in annual P yield resulting from conversion of forest to residential land use was 7 kilograms per square kilometer, not including septic-tank system contributions. Calculated loadings from septic systems were found to correlate best with the number of near-shore dwellings around each lake in 1940. The regression equation expressing this relationship explained 36 percent of the sample variance. There was no significant correlation between estimated septic-tank system P loadings and numbers of dwellings present in 1960 or 1970. The evidence indicates that older systems might contribute more phosphorus to lakes than newer systems, and that there may be substantial time lags between septic-system installation and significant impacts on lake-water P concentrations. For lakes in basins that contain agricultural land, the P loading attributable to agriculture can be calculated as the difference between the estimated total loading and the sum of estimated loadings from all other (nonagricultural) sources. A comprehensive system for evaluating errors in all loading estimates is presented. The empirical relationships developed allow preliminary approximations of the cumulative impact that development has had on P loading and the amounts of P loading from generalized land-use categories for Puget Sound lowland lakes. In addition, the sensitivity of a lake to increased loading can be evaluated using the mass-balance model. The methods use data that are presently available for most lakes. All the estimates are most suitable for use in developing water-quality goals, setting priorities for lake studies, and designing studies of individual lakes. The suitability of the method for management of individual lakes will often be limited by relatively high levels of uncertainty, especially if the method is used to evaluate relatively small increases in P loading.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr82161","usgsCitation":"Gilliom, R.J., 1983, Estimation of nonpoint sources of phosphorus for lakes in the Puget Sound region, Washington: U.S. Geological Survey Open-File Report 82-161, iv, 42 p., https://doi.org/10.3133/ofr82161.","productDescription":"iv, 42 p.","costCenters":[],"links":[{"id":405423,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0161/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":142172,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0161/report-thumb.jpg"}],"country":"United States","state":"Washington","otherGeospatial":"Puget Sound region","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -124.69482421875,\n              47.07012182383309\n            ],\n            [\n              -121.871337890625,\n              47.07012182383309\n            ],\n            [\n              -121.871337890625,\n              48.8936153614802\n            ],\n            [\n              -124.69482421875,\n              48.8936153614802\n            ],\n            [\n              -124.69482421875,\n              47.07012182383309\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ae4b07f02db5fb265","contributors":{"authors":[{"text":"Gilliom, Robert J. rgilliom@usgs.gov","contributorId":488,"corporation":false,"usgs":true,"family":"Gilliom","given":"Robert","email":"rgilliom@usgs.gov","middleInitial":"J.","affiliations":[{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true}],"preferred":true,"id":159162,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The impacts of subsidence are potentially severe in terms of damage to surface utility lines and structures, changes in surface-water and ground-water conditions, and effects on vegetation and animals. Although subsidence cannot be eliminated, it can be reduced or controlled in areas where deformation of the ground surface would produce dangerous or costly effects. \r\n\r\nSubsidence prediction is highly developed in Europe where there are comparatively uniform mining conditions and a long history of field measurements. Much of this mining has been carried out beneath crowded urban and industrial areas where accurate predictions have facilitated use of the surface and reduced undesirable impacts. Concerted efforts to understand subsidence processes in the United States are recent. Empirical methods of subsidence analysis and prediction based on local conditions seem better suited to the current state of knowledge of the varied geologic and topographic conditions in domestic coal mining regions than do theoretical/mathematical approaches. In order to develop broadly applicable subsidence prediction methods and models for the United States, more information is needed on magnitude and timing of ground movements and geologic properties.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/cir876","usgsCitation":"Lee, F.T., and Abel, J., 1983, Subsidence from underground mining; environmental analysis and planning considerations: U.S. Geological Survey Circular 876, iv, 28 p. :ill., maps ;26 cm., https://doi.org/10.3133/cir876.","productDescription":"iv, 28 p. :ill., maps ;26 cm.","costCenters":[],"links":[{"id":124669,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/circ/1983/0876/report-thumb.jpg"},{"id":30794,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/circ/1983/0876/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db699ae9","contributors":{"authors":[{"text":"Lee, Fitzhugh T.","contributorId":82272,"corporation":false,"usgs":true,"family":"Lee","given":"Fitzhugh","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":147500,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Abel, John F.","contributorId":84351,"corporation":false,"usgs":true,"family":"Abel","given":"John F.","affiliations":[],"preferred":false,"id":147501,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

These induced compressive stresses are predicted by computer calculations, but have never been adequately confirmed by field measurements, owing primarily to the unique difficulties of obtaining such field data. Vibrating-wire stressmeter measurements made near the Mighty Epic nuclear detonation, however, qualitatively indicate that within 150 meters of the working point, permanent compressive stress increases of several megapascals were present 15 weeks after the event. Additionally, stress-change magnitudes interpreted from the stressmeter data between the 75- and 260-meter range from the working point compare favorably with calculational predictions of the stress changes believed to be present shortly after detonation of the event. The measurements and calculations differ, however, with regard to the pattern of stress change radial and transverse to the explosion source. For the range of the field measurements from the working point, computer models predict the largest compressive-stress increase to be radial to the explosion source, while the field data indicate the transverse component of. stress change to be the most compressive. The significance of time-dependent modification of the initial explosion-induced stress distribution is, however, uncertain with regard to the comparison of the field measurements and theoretical predictions.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr83642","usgsCitation":"Ellis, W., and Kibler, J., 1983, Explosion-induced stress changes estimated from vibrating-wire stressmeter measurements near the Mighty Epic event, Nevada Test Site: U.S. Geological Survey Open-File Report 83-642, i, 28 p. ill., maps ;28 cm., https://doi.org/10.3133/ofr83642.","productDescription":"i, 28 p. ill., maps ;28 cm.","costCenters":[],"links":[{"id":142035,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1983/0642/report-thumb.jpg"},{"id":36313,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1983/0642/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ee4b07f02db5fdea6","contributors":{"authors":[{"text":"Ellis, William L.","contributorId":89128,"corporation":false,"usgs":true,"family":"Ellis","given":"William L.","affiliations":[],"preferred":false,"id":158231,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kibler, J.D.","contributorId":68311,"corporation":false,"usgs":true,"family":"Kibler","given":"J.D.","email":"","affiliations":[],"preferred":false,"id":158230,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

In a few places the anomalies are caused by intrusions. Correlation between magnetic properties measured from rock samples and those derived from rock unit-magnetic anomaly associations is excellent. Anomaly characteristics, extensive magnetic gradients, and marked changes in the regional magnetic field can be coupled with the magnetic properties of the rock units to delineate structural boundaries. Three major boundaries are indicated by contrasts in regional magnetic expressions. Less extensive but more clearly indicated boundaries in the immediate vicinity of Yucca Mountain are interpreted from a distinctive pairing of northerly-trending linear positive and negative anomalies which are caused by vertical displacement in generally gently dipping volcanic beds. The displacement between beds is located approximately along the border line between the linear anomaly pairs. One series of pairs of more northeasterly trend lies over the general location of a change from moderately thick to very thick volcanic units that was interpreted from gravity data.

High aeroradioactivity is associated with potassium-rich granitic plutons, muscovite-rich gneisses, schists, and metavolcanic rocks; positive gravity and magnetic anomalies are associated with gabbro plutons; and negative gravity anomalies are associated with granitic plutons. \r\n\r\nAt the west side of the slate belt, the Tillery phyllite is interpreted as having undergone progressive metamorphism. The underlying Uwharrie Formation extends into the Charlotte belt where it is mapped as metavolcanic rocks. Gravity models of the Carolina slate belt indicate that it is a synform containing a wedge of metasedimentary and volcanoclastic rock on plutonic basement. The basement is exposed in the adjacent Charlotte belt antiform. \r\n\r\nThe northern Charlotte belt contains mainly plutonic rocks which have been divided into 3 supergroups of plutons based upon chemistry, mineralogy, texture, and age. They are: \r\n\r\n1. Old Plutonic supergroup - plutons 545-490 m.y. that are medium to coarse-grained tonalite, quartz diorite, and granodiorites. \r\n\r\n2. Concord-Salisbury supergroup -- plutons 426-350 m.y. which form sheet-like intrusions of differentiated gabbro; local volcanic centers with ring complexes 13 km in diameter that suggest magma chambers 0 - 8 km deep; smaller bodies of diorite, monzonite, and syenite; and small Salisbury type granodiorites. \r\n\r\n3. Landis supergroup -- plutons 350-280 m.y. that are usually very coarse-grained, porphyritic, 'big feldspar,' potassium-rich granites. \r\n\r\nThe Mecklenburg-Weddington gabbro complex of the Concord-Salisbury supergroup, the largest feature in the study area, contains three large gabbro plutons. The gabbro intruded old Plutonic complex rocks and could-have produced the metamorphic reaction K-feldspar + sillimanite quartz + muscovite reflected in the mineral assemblage of adjacent felsic metavolcanic rocks. Gravity models indicate a lopolith 3.5- to 4.5-km thick with a 2 km sill extending to the northeast. Positive magnetic and gravity anomalies suggest the lopolith is. connected with the Concord gabbro complex to the northeast. \r\n\r\nThe sheet-like intrusions of Concord-Salisbury group gabbros, forming the core of the composite 5atholith, have medium-grained Salisbury type granodiorite above, and coarser-grained Landis granite below. The position of the supergroups as presently exposed may be a function of level of erosion versus level of emplacement. The plutons in the composite batholith span 200 m.y. according to current age data and are arranged with the oldest at the top and the youngest at the bottom. However, Rb-Sr and K-At ages in the Piedmont are more likely to reflect age of crustal uplift than the age of metamorphism or intrusion. The Charlotte belt composite batholith, therefore, may very well be the result of a shorter single tectonic event or process.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr8393","usgsCitation":"Wilson, F., 1983, Geophysical and geologic studies in southern Mecklenburg County and vicinity, North Carolina and South Carolina: U.S. Geological Survey Open-File Report 83-93, 199 p.  ill., maps ;28 cm., https://doi.org/10.3133/ofr8393.","productDescription":"199 p.  ill., maps ;28 cm.","costCenters":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"links":[{"id":39562,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1983/0093/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":39561,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1983/0093/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":39563,"rank":402,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1983/0093/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":39564,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1983/0093/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":144993,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1983/0093/report-thumb.jpg"}],"country":"United States","state":"North Carolina, South Carolina","county":"Mecklenburg County","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -81.19308471679688,\n              34.84762101276787\n            ],\n            [\n              -81.19308471679688,\n              35.74316846139925\n            ],\n            [\n              -80.4144287109375,\n              35.74316846139925\n            ],\n            [\n              -80.4144287109375,\n              34.84762101276787\n            ],\n            [\n              -81.19308471679688,\n              34.84762101276787\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac8e4b07f02db67c208","contributors":{"authors":[{"text":"Wilson, Frederick A.","contributorId":100352,"corporation":false,"usgs":true,"family":"Wilson","given":"Frederick A.","affiliations":[],"preferred":false,"id":163574,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

H. Darton at the turn of the century. Since then, hydrogeologists have debated the source of the large quantities of water which have been discharged by artesian flow from the Dakota. Among suggestions for the source of this water are (1) recharge of the aquifer at outcrops in the Black Hills, (2) compaction and compressive storage within the aquifer, (3)leakage through confining layers, and (4) upward flow from the underlying Madison Group limestones. \r\n\r\nA series of increasingly refined models of the aquifer system in South Dakota have been developed and used for numerical simulations of the ground-water flow. The simulations have provided estimates of leakage through the confining layers. The results indicate that, before development, most of the flow into and out of the Dakota Sandstone occurred as leakage through confining layers and, since development, most of the water released from storage has come from the confining layers. \r\n\r\nIn situ and laboratory hydraulic conductivity measurements have been made for the Cretaceous shale confining layer which overlies the Dakota. These data indicate hydraulic conductivities which are one to three orders of magnitude lower than the conductivities indicated by the numerical analyses; this suggests that the leakage through the confining layer is largely through fractures. The fractures apparently did not influence the laboratory and in situ measurements. \r\n\r\nTo test the conception of flow in the aquifer-confining layer system derived from our analyses, the transport of sulfate in the system was simulated. Simulations using a numerical ground-water transport model were reasonably successful in explaining the present distribution of sulfate in the system. This result increases confidence in the flow system implied by the flow simulations in which leakage through confining layers is dominant.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wsp2237","usgsCitation":"Bredehoeft, J.D., Neuzil, C., and Milly, P.C., 1983, Regional flow in the Dakota aquifer: A study of the role of confining layers: U.S. Geological Survey Water Supply Paper 2237, iv, 45 p., https://doi.org/10.3133/wsp2237.","productDescription":"iv, 45 p.","costCenters":[],"links":[{"id":411005,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_25541.htm","linkFileType":{"id":5,"text":"html"}},{"id":25731,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wsp/2237/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":138082,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wsp/2237/report-thumb.jpg"}],"country":"United States","state":"Nebraska, South Dakota","otherGeospatial":"Dakota aquifer","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -96.432,\n              45.946\n            ],\n            [\n              -104.049,\n              45.946\n            ],\n            [\n              -104.049,\n              42.477\n            ],\n            [\n              -96.432,\n              42.477\n            ],\n            [\n              -96.432,\n              45.946\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a27e4b07f02db610782","contributors":{"authors":[{"text":"Bredehoeft, John D.","contributorId":86747,"corporation":false,"usgs":true,"family":"Bredehoeft","given":"John","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":143104,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Neuzil, C.

A previously published steady-state finite-difference digital model was converted to a transient-state model by changing boundary conditions and adding storage coefficients.

As much as 300 feet of additional drawdown were simulated for the maximum amount of coal development. Drawdowns near pumping wells are not predicted.

Large in 1979 and 1980 has been redesigned to permit its use in a computer-assisted search for exploration-target areas in Devonian rocks of the Appalachian region using attribute-coincidence mapping (ACM). Some 36 gridded-data maps and selected maps derived therefrom were developed to show the orthogonal patterns, using the 7-1/2 minute quadrangle as an information cell, of geologic data patterns relevant to the empirical model. From these map and data files, six attribute-coincidence maps were prepared to illustrate both variation in the application of ACM techniques and the extent of possible significant exploration-target areas. As a result of this preliminary work in ACM, four major (and some lesser) exploration-target areas needing further study and analysis have been defined as follows: 1) in western and central New York in the outcrop area of lowermost Upper Devonian rocks straddling the Clarendon-Linden fault; 2) in western Virginia and eastern West Virginia in an area largely coincident with the well-known 'Oriskany' Mn-Fe ores; 3) an area in West Virginia, Maryland, and Virginia along and nearby the trend of the Alabama-New York lineament of King and Zietz approximately between 38- and 40-degrees N. latitude; and 4) an area in northeastern Ohio overlying an area coincident with a significant thickness of Silurian salt and high modern seismic activity. Some lesser, smaller areas suggested by relatively high coincidence may also be worthy of further study.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr83352","usgsCitation":"Wedow, H., 1983, A search for stratiform massive-sulfide exploration targets in Appalachian Devonian rocks; a case study using computer-assisted attribute-coincidence mapping: U.S. Geological Survey Open-File Report 83-352, 84 p. maps ;28 cm., https://doi.org/10.3133/ofr83352.","productDescription":"84 p. maps ;28 cm.","costCenters":[],"links":[{"id":146100,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1983/0352/report-thumb.jpg"},{"id":39464,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1983/0352/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b18e4b07f02db6a7031","contributors":{"authors":[{"text":"Wedow, Helmuth","contributorId":67495,"corporation":false,"usgs":true,"family":"Wedow","given":"Helmuth","affiliations":[],"preferred":false,"id":163428,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
