Mean uranium content of 108 samples of granitic rock is 8.8 parts per million (ppm), more than twice normal for rocks of this composition. The mean thorium content, 20.3 ppm, and mean Th/U, 3.19, are normal. The most uraniferous and fertile rocks are the peraluminous two-mica granitic suite, although not all two-mica plutons are enriched in uranium. The muscovite-bearing suite has mean uranium content of 22.3 ppm, mean thorium content of 22.8 ppm, and mean Th/U of 2.82. Porphyritic quartz monzonite of the Midnite mine, which I interpret to be a two-mica granitic rock, is especially radioactive with mean U of 14.7 ppm, mean Th of 32.1 ppm, and mean Th/U of 2.72. Mean uranium and thorium contents of the two-mica granitic plutons are significantly different from those of the calcalkaline hornblende granitic suite, which are mean U, 5.0 ppm; mean Th, 17.6; and mean Th/U, 3.78. Biotite granitic rocks containing no hornblende or muscovite appear to be an intermediate suite in terms of U and Th, or possibly are variants of both hornblende and muscovite type; mean U is 3.88 ppm, mean Th is 14.4 ppm, and mean Th/U is 3.03 as calculated from the more abundant data of Castor and others (1978). occurrence of uranium and thorium in the muscovite and hornblende suites is systematically different. Many muscovite-bearing rocks are much more enriched in uranium (>15 ppm) than they are in thorium, and have a relatively low Th:U correlation coefficient of +0.409. Many of the uraniferous muscovite-bearing rocks contain less than 20 ppm Th, probably a consequence of forming by anatexis of thorium deficient sedimentary rocks. Uranium and thorium variation is much more regular in the hornblende suite, which has a Th:U correlation coefficient of +0.780. Uranium in the muscovite suite is held primarily in magnetite and biotite, and possibly as minute uraninite grains, whereas in the hornblende suite uranium resides primarily in sphene, zircon, and allanite. Many muscovite-bearing plutons are considered fertile by the following two criteria: high uranium content, and uranium residence in labile phases. The hornblende-bearing granitic plutons are not considered fertile, regardless of uranium content, because uranium resides in refractory phases. \r\n\r\nTwenty-one sample localities in four plutons are considered highly anomalous according to one or more of the following attributes: (1) Uranium content =115.8 ppm (total population mean plus 1 d). (2) Thorium content =30.3 ppm (mean plus 1 d) and uranium =8.8 ppm (mean). (3) Th/U lower than 1.68 (mean minus 1 d) and uranium content -18.8 ppm. The four identified highly anomalous plutons are, from southwest to northeast, (1) Cretaceous porphyritic quartz monzonite of the Midnite mine; (2) Cretaceous muscovite quartz monzonite east of Deer Lake; (3) Cretaceous quartz monzonite of Hungry Mountain, and (4) Cretaceous quartz monzonite of Granite Pass. The study area is favorable for at least five types of uranium deposits including: intragranitic hydrothermal veins as in the Massif Central, France; intragranitic supergene veins, as at the Daybreak mine; contact zone deposits, as at the Midnite mine; and basal-type sandstone deposits, as at the Sherwood mine. The fifth type is Rossing-type deposits for which the high-grade metamorphic terrane of the Kettle River Range, Ferry County, seems favorable, if sufficient volume of low-tenor rock can be located. The first four deposit types seem most likely in or adjacent to uraniferous plutons, as no other uranium source rocks have been identified in the area. Contact zone deposits and intragranitic hydrothermal veins, both possibly supergene-enriched, and basal-type deposits in Tertiary sandstone and conglomerate, seem most likely to be of economic importance.

The U. S. Geological Survey recovered eight sediment cores from beneath Clear Lake, Lake County, California, in 1973. The locations of the core sites are shown in fig. 1; lithologic descriptions of the cores, as well as radiographs, have been given by Sims and Rymer (1975a-g, 1976). A list of the procedures followed in sampling the cores and a list of the samples taken may be found in Beaver and others (1975); fish remains from two of the cores have been studied by Casteel and others (1975, 1977a,1977b). This report gives raw count data for 72 pollen samples from core 7, a 27.4-m long core from the southern or Highlands Arm of the lake (fig. 1).

Pollen counts for core 4, a 115-m core from the main basin of the lake, are given in Adam (1979); that core spans the time interval between the end of the penultimate glacial period, about 130,000 years ago, and the present.

central observation manhole was developed on Long Island, N.Y., to study the role of the unsaturated zone during aquifer recharge with tertiary-treated sewage. The manhole extends through most of the 7.5-meter-thick unsaturated zone, which is composed of glacial outwash sand and gravel, and enables collection of water samples and monitoring of dynamic characteristics of the unsaturated zone during recharge experiments. The system contains instrumentation for monitoring infiltration rate, pressure-head distribution, soil-moisture content, ground-water levels, and soil gases. The 24.55-square-meter recharge basin has operated in all seasons intermittently since April 1975 and, as of April 1978, has transmitted 62 million liters of tertiary-treated effluent to the water-table aquifer. Overall performance of the facility indicates that it is suitably designed for monitoring the unsaturated zone during artificial-recharge experiments.

Forty oil samples from across the North Slope of Alaska have been analyzed by the U.S. Bureau of Mines and the U.S. Geological Survey. Results of these analyses suggest two separate genetic oil types. The first type, the Simpson-Umiat oil type, occurs in reservoir rocks of Cretaceous and Quaternary age and includes oils from seeps in the Skull Cliff, Cape Simpson, Manning Point, and Ungoon Point areas; the Wolf Creek test well 3, and the Umiat oil field. These are higher gravity, low-sulfur oils with no, or slight, odd-numbered n-alkane predominance and pristane to phytane ratios greater than 1.5. The second type, the Barrow-Prudhoe oil type, occurs in reservoir rocks of Carboniferous to Cretaceous age and includes oils from South Barrow gas field, Prudhoe Bay oil field, and the Fish Creek test well 1. Physical properties of Barrow-Prudhoe oils are variable, but in general the oils are medium-gravity, high-sulfur oils with a slight even-numbered n-alkane predominance and pristane to phytane ratios of less than 1.5. The two types are believed to originate from different source rocks; the Barrow-Prudhoe type may have originated from a carbonate or other iron-deficient source rock, and the Simpson-Umiat type from a siliciclastic source rock. Occurrences of the two oil types, when outlined on a map, indicate at least two exploration fairways. The fairway for the Barrow-Prudhoe type is along the Barrow arch, and the fairway for the Simpson-Umiat type is the area of the best reservoir development for the Nanushuk Group.

Two aspects of land utilization were studied for this report: (1) the seismic and geotechnical properties of a landslide and (2) the seismic, magnetic, and geotechnical properties of clinker deposits. \r\n\r\n(1) The landslide seismic survey revealed two layers in the slide area. The upper (low-velocity) layer is a relatively weak mantle of colluvium and unconsolidated and weathered bedrock that ranges in thickness from 3.0 to 7.5 m and has an average seismic velocity of about 390 m/s. It overlies high-velocity, relatively strong sedimentary bedrock that has velocities greater than about 1330 m/s. The low-velocity layer is also present at the other eight seismic refraction sites in the basin; a similar layer has also been \r\nreported in the Soviet Union in a landslide area over similar bedrock. The buried contact of the low- and high-velocity layers is relatively smooth and is nearly parallel with the restored topographic surface. There is no indication that any of the high-velocity layer (bedrock) has been displaced or removed. \r\n\r\nThe seismic data also show that the shear modulus of the low-velocity layer is only about one-tenth that of the high-velocity layer and the shear strength (at failure) is only about one-thirtieth. Much of the slide failure is clearly in the shear mode, and failure is, therefore, concluded to be confined to the low-velocity layer. The major immediate factor contributing to landslide failure is apparently the addition of moisture to the low-velocity layer. \r\n\r\nThe study implies that the low-velocity layer can be defined over some of the basin by seismic surveys and that they can help predict or delineate potential slides. Preventative actions that could then be taken include avoidance, dewatering, prevention of saturation, buttressing the toe, and unloading the head. The low-velocity layer is usually less than about 5 m thick and may be excavated by dozing, whereas the bedrock must be blasted. Thus, it would seem economically feasible to underpin a structure to nonweathered bedrock or, perhaps, to remove the low-velocity layer prior to construction. \r\n\r\n(2) Many coal beds in the Powder River Basin have burned along their outcrops, and the resulting intense heat has baked and fused the overlying clastic (sedimentary) rocks into clinkers. The clinkers are very magnetic and a buried edge of a single layer of burn can easily be located by magnetic prospecting methods. Location of the edge is very important in estimating unburned coal deposits, locating clinker quarries, and planning drilling of seismic reflection lines.\r\n\r\nThe clinkers are very porous and highly fractured,-and seismic and geotechnical tests show that they have relatively low strength and competency. Many of the laboratory tests, however, are inherently biased because the clinkers are so highly fractured that only competent samples are selected. The laboratory tests, for example, show that clinkers must be loosened by heavy ripping tractors or blasting, whereas the field data and practical experience indicate that clinkers may be mined with light equipment. \r\n\r\nHeavy structures such as coal silos and bridge abutments may have to be sited on clinkers. However, differential settlement may occur, with failure in the shear mode, because chimneys of relatively greater strength occur among the weaker clinkers. Preliminary data indicate that the chimneys may be located by magnetic or possibly seismic surveys. Special foundation-preparation techniques could be used or, perhaps, the chimneys could be avoided altogether at a construction site.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr79952","usgsCitation":"Miller, C., 1979, Seismic, magnetic, and geotechnical properties of a landslide and clinker deposits, Powder River basin, Wyoming and Montana: U.S. Geological Survey Open-File Report 79-952, iv, 47 p.:ill., maps ;28 cm., https://doi.org/10.3133/ofr79952.","productDescription":"iv, 47 p.:ill., maps ;28 cm.","costCenters":[],"links":[{"id":143460,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1979/0952/report-thumb.jpg"},{"id":38176,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/0952/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adbe4b07f02db685c1b","contributors":{"authors":[{"text":"Miller, C.H.","contributorId":19148,"corporation":false,"usgs":true,"family":"Miller","given":"C.H.","email":"","affiliations":[],"preferred":false,"id":161200,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":61612,"text":"gq1514 - 1979 - Geologic map of the Plug Hat Rock quadrangle, Moffat County, Colorado","interactions":[],"lastModifiedDate":"2012-02-10T00:10:51","indexId":"gq1514","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1979","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":316,"text":"Geologic Quadrangle","code":"GQ","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"1514","title":"Geologic map of the Plug Hat Rock quadrangle, Moffat County, Colorado","language":"ENGLISH","doi":"10.3133/gq1514","isbn":"0607755423","usgsCitation":"Rowley, P.D., and Hansen, W.R., 1979, Geologic map of the Plug Hat Rock quadrangle, Moffat County, Colorado: U.S. Geological Survey Geologic Quadrangle 1514, 1 map : col. ;58 x 45 cm., https://doi.org/10.3133/gq1514.","productDescription":"1 map : col. ;58 x 45 cm.","costCenters":[],"links":[{"id":102615,"rank":700,"type":{"id":15,"text":"Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_1064.htm","linkFileType":{"id":5,"text":"html"},"description":"1064"},{"id":247918,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/gq/1514/report.pdf","size":"32","linkFileType":{"id":1,"text":"pdf"}},{"id":252343,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/gq/1514/report-thumb.jpg"}],"scale":"24000","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -109,40.25 ], [ -109,40.3675 ], [ -108.86749999999999,40.3675 ], [ -108.86749999999999,40.25 ], [ -109,40.25 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aefe4b07f02db6916af","contributors":{"authors":[{"text":"Rowley, Peter D.","contributorId":27435,"corporation":false,"usgs":true,"family":"Rowley","given":"Peter","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":266136,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hansen, Wallace R.","contributorId":90273,"corporation":false,"usgs":true,"family":"Hansen","given":"Wallace","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":266137,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":61534,"text":"mf1158 - 1979 - Aeromagnetic map and associated depth map of the Upper Mississippi Embayment region","interactions":[],"lastModifiedDate":"2016-08-23T10:46:45","indexId":"mf1158","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1979","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":325,"text":"Miscellaneous Field Studies Map","code":"MF","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"1158","title":"Aeromagnetic map and associated depth map of the Upper Mississippi Embayment region","docAbstract":"

Phytoplankton concentrations in cells per milliliter (cells/mL) were generally higher downstream from Atlanta than upstream. The highest concentrations, mostly blue-green algae, occurred in West Point Lake with an average of 90,000 cells/mL for the sampling period. The lowest concentrations, 1,000 cells/mL, occurred upstream of Lake Sidney Lanier. Dissolved orthophosphate and nitrite plus nitrate concentrations were highest in the river reaches and upper reaches of the two lakes and were lowest at the dam pools of both lakes. The high nitrite plus nitrate concentrations downstream from Atlanta were primarily a result of nitrification by Nitrosomonas and Nitrobacter bacteria. Algal growth potential was highest downstream from Atlanta, 25 milligrams per liter (mg/L) at Whitesburg, and was the lowest in the headwaters and at the dam pools of Lake Sidney Lanier and West Point Lake. The rate of nitrification in the Atlanta to Franklin reach of the river was comparatively low, 0.02 mg/L per hour. Nitrification was an important cause of dissolved-oxygen consumption in a 45-mi reach of the river downstream from the Atlanta wastewater treatment facilities.

This report presents the results of a three-year study of suspended sediments within the South Texas OCS region. The investigations were a part of the environmental studies of the South Texas Outer Continental shelf sponsored by the Bureau of Land Management. The physical properties of the suspended particulate system studied were the turbidity of the water and the texture of the suspended particulates. The objective of the study was to determine the spatial and temporal variability in the distribution of suspended sediments in an effort to gain insight into the regional sediment transport system.

This effect is believed to be due to the increased radiation in the ore coupled with the faster rate of fading of low-temperature thermoluminescence compared to high-temperature thermoluminescence. Both the ratios of thermoluminescent responses from any of a variety of temperature ranges and glow curves (plots of intensity of thermoluminescence versus temperature) can be used to detect the increased importance of high-temperature thermoluminescence relative to low-temperature thermoluminescence of previously mineralized samples. Both ratios and glow curves present a systematic pattern around this deposit; these patterns may have application in uranium prospecting.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr79774","usgsCitation":"Spirakis, C.S., 1979, Interpretation of thermoluminescence patterns around a Wyoming roll-type uranium deposit: U.S. Geological Survey Open-File Report 79-774, ii, 22 p. :graphs ;28 cm., https://doi.org/10.3133/ofr79774.","productDescription":"ii, 22 p. :graphs ;28 cm.","costCenters":[],"links":[{"id":143267,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1979/0774/report-thumb.jpg"},{"id":39088,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/0774/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49dae4b07f02db5e00df","contributors":{"authors":[{"text":"Spirakis, Charles S.","contributorId":97111,"corporation":false,"usgs":true,"family":"Spirakis","given":"Charles","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":162869,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":65773,"text":"i1242 - 1979 - Preliminary pictorial map of Ganymede","interactions":[],"lastModifiedDate":"2012-02-02T00:13:17","indexId":"i1242","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1979","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":320,"text":"IMAP","code":"I","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"1242","subseriesTitle":"NONE","title":"Preliminary pictorial map of Ganymede","language":"ENGLISH","doi":"10.3133/i1242","usgsCitation":"Water Resources Division, U.S. Geological Survey, 1979, Preliminary pictorial map of Ganymede: U.S. Geological Survey IMAP 1242, 3 maps ;on sheet 84 x 74 cm., https://doi.org/10.3133/i1242.","productDescription":"3 maps ;on sheet 84 x 74 cm.","costCenters":[],"links":[{"id":189155,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":101134,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/imap/1242/plate-1.pdf","size":"5683","linkFileType":{"id":1,"text":"pdf"}}],"scale":"25000000","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4afce4b07f02db69657d","contributors":{"authors":[{"text":"Water Resources Division, U.S. Geological Survey","contributorId":128075,"corporation":true,"usgs":false,"organization":"Water Resources Division, U.S. Geological Survey","id":534131,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":9618,"text":"ofr791164 - 1979 - Design of a network for monitoring ground-water quality in Minnesota","interactions":[],"lastModifiedDate":"2018-03-12T12:05:54","indexId":"ofr791164","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1979","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":"79-1164","title":"Design of a network for monitoring ground-water quality in Minnesota","docAbstract":"

A network for monitoring the quality of water in the 13 principal aquifers in Minnesota has been designed and more than 400 wells and springs selected for sampling. The network organization includes four major elements; (1) point sampling, (2) point monitoring, (3) regional monitoring, and (4) site-specific monitoring. These elements constitute monitoring strategies designed to define baseline conditions and monitor major time-and-space trends of more than 60 water-quality parameters.

The proposed Big Frog Wilderness is comprised of approximately 1820 hectares (18.2 km2) of mountainous terrain in the Cherokee and Chattahoochee National Forests south of the Ocoee River in Polk County, Tennessee, and Fannin County, Georgia. Rocks of the study area are greenschist-facies metasandstone, meta-arkose, metagraywacke, and dark slate of the Ocoee Supergroup of late Precambrian age. A major thrust fault, correlated with the Greenbrier Fault, separates fine-grained slaty rocks of the Snowbird Group on the northwest side, from coarse clastic sediments and interbedded slates of the Great Smoky Group on the southeast. North- and northeast-trending folds are common in the map area. Minor deposits of Quaternary sand and gravel occur locally in the lower parts of large streams.

Semiquantitative spectrographic, atomic absorption, and selected fire assay analyses were done on more than 200 samples of rock, soil, and stream sediment. No significant metal anomalies were found for 31 major, minor, and trace elements. In many places, metasiltstone and metasandstone contain trace amounts of chalcopyrite and sphalerite as microscopic intergrowths with the chief sulfide minerals, pyrite and pyrrhotite. Sulfides make up as much as 5 to 10 percent of some rocks and provide concentrations of Cu, Zn, and As slightly higher than background in samples of rock and soil. Rocks containing these disseminated base-metal sulfides are of insufficient grade to have current economic potential, however.

No metallic mineral resources are known within the proposed Big Frog Wilderness. Nonmetallic resources, including slate and  phyllite, stone, and sand and gravel are present locally, but are not presently a value because similar resources exist closer to markets outside the study area. These deposits therefore would have only marginal use in the region.

This report summarizes ground-water availability in the lower Colorado region and discusses the potential for greater ground-water development and increased efficiency of water use.

\n

The climate in the most highly developed southwestern part of the region is warm and dry and that in the northeastern part is cool and moist to dry. Although the regional average annual precipitation is only about 14 inches and most streambeds are dry during most of the year, about 1.5 billion acre-feet of ground water of moderate to good chemical quality is stored in aquifers of the region. Much of the water use is founded on pumped withdrawal of ground water. However, in most of the southwestern part of the region pumpage and consumptive use are in excess of replenishment, resulting in declining water levels. In the southwestern part of the region, water levels generally are from 200-500 feet below land surface and in large areas are less than 200 feet. Large-diameter water wells in this part of the region commonly produce 500-1 ,500 gallons per minute of water. In the northeastern part of the region, water levels generally are more than 500 feet below land surface, but in some large areas water levels are from 200-500 feet, and locally are less than 200 feet below the surface. In the northeastern part of the region, water wells generally have lower yields than those to the southwest. The yields range from a few to 2,000 gallons per minute, but most wells yield from 10 to less than 500 gallons per minute. In the southwestern part of the region about 1 billion acre-feet of ground water is recoverable from storage from the water table to a depth of 700 feet below the land surface. In the northeast about 150 million acre-feet can be recovered by dewatering a 100-foot-thick section of a typical aquifer (16 million-acre area). The estimated current annual rate of ground-water depletion, occurring almost entirely in the southwestern part of the region, is 2.4-3.2 million acre-feet per year. Almost 6 million acre-feet is pumped each year-about 90 percent for agriculture, 6 percent for public supply, and 3 percent for industrial use. The percentage of use for public supply and industry is increasing each year.

\n

The potential for greater development of ground water in the southwestern part of the region is constrained by land subsidence, earth cracks, increasing costs of pumping and transportation, and moderate to poor chemical quality of water. More ground water can be developed in the northeastern part of the region, where the major constraint is pumping cost owing to low to moderate well yields and depth to water. Some benefits can be realized everywhere in the region through changes in current use and greater efficiencies of use. Additional supplies may be made available by capture of natural evapotranspiration. Increasing the efficiency of use is possible hydrologically but, in the near term, is more expensive than increasing groundwater development. Decrease of irrigation, change to water-saving methods of irrigation, use of saline water, decrease of per capita public- supply use, and more reuse of water in almost every type of use could help extend the supply and thereby reduce the current rate of ground-water depletion. Financial problems have not yet caused an overall decrease in pumpage, but, locally, operating costs or partial dewatering of the aquifer has eliminated or decreased withdrawal. Current water laws in all States of the region, except Arizona, control or allocate the use of ground water.
