Sedimentary clay that crops out in the coastal plains of New Jersey, Delaware, the part of Maryland north and east of Washington, B.C., and the northeast half of Washington, D.C., in the nonmarine Cretaceous Potomac Group is predominantly kaolinite and illite. In contrast, in part of southeastern Maryland, the southwest half of Washington, D.C., and most of eastern Virginia, Potomac Group clay is predominantly montmorillonite.
Kaolinite and illite were probably derived by intense acid weathering of metamorphic and granitic rocks to the west during the Cretaceous and were deposited in a well-drained basin. Montmorillonite was most likely produced by deep weathering of a mainly granitic source. Poor drainage and alkaline surface- and ground-water conditions probably accompanied the production, transportation, deposition, and burial of the montmorillonite. Kaolinization of the montmorillonite is taking place now at the surface in northern Virginia.

Volcanoes of this type are known as \"tuyas.\" The Togiak tuya erupted into an intraglacial lake in a hole thawed through a glacier that occupied Togiak Valley in Pleistocene time. The eruption was localized along the Togiak fault, which defines the east side of a shallow graben that is floored by older olivine basalt flows. The tuya, which has an area of 15 square kilometers, is a parallelogram. The flat summit, about 300 meters above the valley floor, is capped by glassy, fine-grained subaerial flows of alkali olivine basalt. To the north, the capping flows overlie palagonitized glassy tuffs; to the south, they overlie pillow basalts and breccia. The elevation of the pillow basalts indicates that surface of the melt-water lake was at least 250 m above present-day sea level. Basalt xenoliths in the tuffs and comparison with other better exposed tuyas suggest that the tuffs probably overlie an older pile of subaqueous pillow basalts that erupted beneath the intraglacial lake. The tuya overlies and is much younger than the preglacial flows on valley floor that yielded a potassium-argon age of 0.758±0.2 million years.

The Western Energy Co.'s Rosebud mine near Colstrip, Mont., was selected as a test site because it typifies surface operations in the Powder River Basin of Montana and Wyoming and elsewhere in the northern Great Plains. Several basic interpretive and analytical remote-sensing techniques were used to identify and delineate various categories of surface-mining operations and concurrent stages of reclamation that characterize most, if not all, such mining operations. Color infrared and black-and-white aerial photographs and a black-and-white band 5 Landsat image were used to identify (1) high wall and bench areas, (2) ungraded spoils, (3) graded and recontoured areas, (4) revegetated recontoured areas, (5) natural and impounded surface water, and (6) miscellaneous areas. Over the lifespan of an extensive surface mine, cultural and natural processes and cumulative environmental effects can be monitored by capitalizing on the close correlation between enhanced satellite imagery, infrared and (or) black-and-white aerial photography, standard large-scale topographic maps (such as U.S. Geological Survey 7½-minute quadrangle maps), and results of onsite inspection of mining and reclamation by Federal or State agencies.

Base-flow losses due to sewering ranging from virtually none at Connetquot River (largely unaffected by urban development) to 211 liters per second, or a 60-percent decrease below natural levels, during 1965-74 at East Meadow Brook (which drains part of highly urbanized Nassau County). Nearly 75 percent of the baseflow loss at East Meadow Brook during 1965-74 was caused by a network of sanitary sewers west of the stream; the remainder resulted from loss of recharge in areas serviced by stream-directed storm sewers. In areas of the Carlls River basin serviced by stream-directed storm sewers, recharge depletion averaged only about 4 liter per second per square kilometer whereas in the more intensely urbanized East Meadow Brook basin, recharge depletion in such areas averaged 18 (L/s)/km2.

An aliquot of the ether solution is pipetted into the cavity of a preformed graphite electrode containing 6 milligrams of sodium carbonate and is evaporated. The carbonate flux prevents formation of refractory tungsten carbide during arcing, resulting in nearly complete volatilization of tungsten during a short exposure period. Spectra from direct-current arc excitation of the tungsten are recorded on film and visually compared to standard spectra.

We used detailed geophysical transects, side-scan sonar, underwater television, and chromatographic analyses of gases in near-surface sediments to define a probable source area of hydrocarbon gases at the southern apex of the water plume epicenter. Geophysical, geotechnical, and geochemical evidence together indicate that hydrocarbon gases of subsurface, thermogenic origin apparently migrate into the near surface sediments along a fault zone.
Subbottom reflector terminations on continuous seismic profiles outline a large zone of anomalous acoustic responses about 9 km in diameter and at 100-m depth that may be caused by a subsurface accumulation of gas. Gas migration from the accumulation to the surface sediment is indicated by smaller zones of reflector terminations observed in high-resolution profiles and by seafloor craters seen on underwater television at one station. The presence of gas-charged surface sediment also is suggested by low percent pore water saturation, greater penetration of the penetrometer, and more rapid penetration of the vibracorer in sediment at the station with near-surface acoustic anomalies and seafloor craters.
Analyses of hydrocarbon gases in sediments from a 1.6-m vibracore taken at this station showed unusually high concentrations of hydrocarbon gases heavier than methane; the ethane, propane, n-butane, and isobutane were 76, 4, 6, and 52 times greater than in other near-surface sediments in this region, and also significant quantities of gasoline-range hydrocarbons were present. The gas composition and presence in near-surface sediments above a thick underlying section with acoustic anomalies points to the possibility of petroleum at depth in this region. Our work indicates that surface and near-surface studies of the continental shelf may contribute significantly to petroleum-resource evaluations in addition to defining areas of potential hazard from gas-charged sediment.
Computer-enhanced Landsat images of the southern Powder River Basin have been used to define facies and linear structural features within the Wasatch Formation. The facies distribution is detectable primarily because of a relation of vegetation density and type to the local substrate. The surface indications of facies are confirmed by sandstone/ mudstone ratios determined from logs of abundant exploration drill holes. These newly defined geologic features are spatially related to known uranium mineral occurrences and are believed to be related to mineralization in the following ways. (1) Major uranium occurrences are virtually restricted to an intermediate grain-size facies of the Wasatch, probably marking the axial zone of the depositional basin. (2) The axial zone is also marked by a change from one structural lineament domain to another, and the structures may have influenced details of fluvial-system patterns and sedimentation and (subsequently) the flow of uranium-bearing ground water. (3) A recently active linear structure may mark the current basin axis; it appears to have some relationship both to groundwater chemistry and the distribution of uranium occurrences, suggesting structural influence on relatively modern ground-water transport and uranium deposition. © 1978 Society of Economic Geologists, Inc.

The basin, about the size of the state of Texas, is underlain by a 2-9 km-thick flat-lying sequence of mostly Cenozoic sediment and rock that includes diatomaceous silty clay interbedded with turbidities in the upper 1 km. Before 1974, geologic and geophysical investigations in the Aleutian Basin were directed at determining its geologic history; more recently, investigations have also been aimed at assessing the basin's hydrocarbon potential. The four major requirements for hydrocarbon accumulation may be present, namely, structural and stratigraphic traps, source rocks, reservoir beds, and an adequate thermal and sedimentation history. Energy resource investigations by the US Geological Survey indicate that: (1) numerous structural features (gentle folds, diapirs, basement ridges) are present in the central and eastern parts of the basin, (2) acoustic features (VAMP's _ Velocity AMPlitude features) that may be due to trapped gases within the sedimentary section are common (over 350 identified) in the central basin, (3) concentrations of organic gases, primarily methane, in the upper 1-3 m beneath the seafloor are very small, they increase with depth, and they are highest in areas near VAMP's, and (4) both the thermal gradient and the sediment thickness are sufficiently great to allow hydrocarbon maturation at depth, if source rocks are present. Adverse conditions in the Aleutian Basin such as excessive water depths and severe weather pose difficult technical problems for the recovery of hydrocarbons that may be present. The data nevertheless suggest the basin is a promising site for hydrocarbon accumulations and therefore warrants further exploration.

Generally, concentrations of constituents were within the range expected in an uncontaminated environment in south Florida. However, concentrations did exceed south Florida background levels or Environmental Protection Agency criteria in a few cases. Two trace elements--chromium (20 micrograms per liter) in ponded surface water and lead (500 micrograms per gram) in bottom sediment--exceeded background levels. Concentrations of dieldrin (22 micrograms per kilogram) and polychlorinated biphenyls (53 micrograms per kilogram) also exceed background levels in bottom sediment. The concentration of phenol (23 micrograms per liter) in ground water exceeded Environmental Protection Agency quality criteria by 22 micrograms per liter, but was within the background range for south Florida. Ten metals were detected in the cattail or algal samples, but only iron, manganese, and zinc were in higher concentrations than those in the bottom sediment.

Infiltration from the Miami Canal and its tributaries is an important source of recharge to the Biscayne aquifer in the vicinity of the Miami Springs-Hialeah well fields. Estimates of pumpage contributed by canal infiltration decreased from nearly 100 percent in the late 1940 's to 50 percent in May 1973 while well field pumpage increased from less than 50 Mgal/d to 120 Mgal/d. As increased withdrawals enlarge the well field 's cone of depression, the threat of saltwater intrusion during dry periods has been increased. Data on water quality, water levels, and canal bottom sediments indicate that sediments greatly impede infiltration from the canals in the areas most affected by pumping. Bottom sediments reduce coliform bacteria, pesticides, PCB, metals, and other suspended materials infiltrating canal water.

Water demand for all uses in Iowa is increasing at an accelerated rate. Demand has increased from about 1,800 million gallons per day in 1955 to 3,500 million gallons per day in 1975 (MacKichan, 1957; Murray and Reeves, 1977). By the year 2020, water demand is expected to be eight times that in 1975 (Barnard and Dent, 1976). Historically, about 75 percent of the demand, excluding that required for power generation, has been met by withdrawals from the water-bearing zones (aquifers) in Iowa's ground-water reservoir. Because this percentage is expected to remain about the same, the anticipated future demands will require extensive withdrawals from the ground-water reservoir. The increasing stress on the ground-water system, which already is severely stressed in several places in the state, will create development and management problems that will require hydrologic information to solve. In order to provide this information, the lowa Geological Survey in cooperation with the U.S. Geological Survey has instituted a series of investigations to define, describe, and evaluate the major aquifers in Iowa's groundwater reservoir. Information from each investigation will be presented in atlas format.

To utilize this natural resource in the most efficient and beneficial manner, a basic knowledge and understanding of its sources and the occurrence and potential of each source must be gained. To provide this knowledge, the Water Resources Division of the U.S. Geological Survey in cooperation with the Iowa Geological Survey compiled this atlas describing the water resources available for development in an 12-county area in east-central Iowa. The report contains information on the availability, quality, and utilization of water from all known sources and the future demands upon the water resources in east-central Iowa. The information is presented to aid water users and other persons searching for and evaluating sources of water in a particular place, and planners and water managers who must consider water resources on a regional basis.

zones in the large ultramafic complex at the Tuolumne River near Sonora, Calif. Bladelike grains of forsterite are elongate, parallel to c, and have prominent idiomorphic faces developed in (010). Metamorphic diopside occurs as small grains, free of inclusions, in rocks containing forsterite. The formation of forsterite and forsterite +diopside in serpentinite probably took place by the following reactions:
antigorite+magnesite→2 forsterite+ fluid 3 antigorite+calcite→4 forsterite+diopside+fluid
Iron derived from the primary olivine and chromite has been oxidized almost entirely to magnetite and may be treated as an indifferent or accessory component. Stratigraphic reconstruction indicates that the total load pressures probably did not exceed 3 kilobars. At these pressures, the reaction should take place between 400° and 500°C with a fluid composition ranging from nearly pure H2O to less than 5 mole percent CO2. The restriction of forsterite and forsterite-f-diopside to shear zones may be attributed to the presence of carbonate in the rock prior to metamorphism and to the dilution of a CO2-bearing fluid phase by water coming from outside the area of the reaction.

The method requires a maximum-stage gage to record the maximum water level attained in the basin during the storm, and a precipitation gage to record storm intensity at regular intervals. The maximum volume of runoff impounded in the basin during a storm is calculated from precipitation data, an arbitrarily estimated runoff coefficient, and the basin's dimensions and infiltration rate. The calculated result is then compared with the recorded maximum water level, and the process is repeated with increased or decreased coefficients on a trial basis until two of the resulting water-storage maxima closely bracket the recorded maximum. The runoff coefficient in effect during that storm is then interpolated or derived graphically from the calculated water-storage maxima. Results of data analyses suggest that a close approximation of a basin's infiltration rate may be used instead of a measured infiltration rate to calculate the runoff coefficient. Differences between measured and calculated runoff coefficients averaged less than 20 percent when based on average infiltration rates adjusted for water temperature and less than 10 percent when based on measured infiltration rates. Accuracy of the calculated runoff coefficient tends to decline as the interval between precipitation measurements increases. Precipitation data collected at 5- and 15-minute intervals gave accurate runoff coefficients regardless of storm duration, but data collected at 30- or 60-minute intervals gave widely varying results.

density of waterfowl nestling sites in marshes, and is being used currently in such areas as the assessment of Pacific porpoise stocks in regions of tuna fishing activity. A mathematical framework for line-transect methodology has only emerged in the last 5 yr. In the present article, we extend this mathematical framework to a line-transect estimator based upon a log-linear model approach.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Ecological Society of America","publisherLocation":"Brooklyn, NY","doi":"10.2307/1936648","usgsCitation":"Anderson, D., Burnham, K., and Crain, B., 1978, A log-linear model approach to estimation of population size using the line-transect sampling method: Ecology, v. 59, no. 1, p. 190-193, https://doi.org/10.2307/1936648.","productDescription":"4 p.","startPage":"190","endPage":"193","numberOfPages":"4","costCenters":[],"links":[{"id":291926,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":291925,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2307/1936648"}],"volume":"59","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53e9d8c5e4b008eaa4f3f5f0","contributors":{"authors":[{"text":"Anderson, David R.","contributorId":8413,"corporation":false,"usgs":true,"family":"Anderson","given":"David R.","affiliations":[],"preferred":false,"id":497793,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Burnham, K.P.","contributorId":63760,"corporation":false,"usgs":true,"family":"Burnham","given":"K.P.","email":"","affiliations":[],"preferred":false,"id":497795,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Crain, B.R.","contributorId":19482,"corporation":false,"usgs":true,"family":"Crain","given":"B.R.","email":"","affiliations":[],"preferred":false,"id":497794,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":70168578,"text":"70168578 - 1978 - Clarence Allen talks about the responsibilities in earthquake prediction","interactions":[],"lastModifiedDate":"2016-03-22T14:25:13","indexId":"70168578","displayToPublicDate":"1978-01-01T00:00:00","publicationYear":"1978","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1435,"text":"Earthquake Information Bulletin (USGS)","active":true,"publicationSubtype":{"id":10}},"title":"Clarence Allen talks about the responsibilities in earthquake prediction","docAbstract":"Dr. Clarence R.
