Extent and source of saltwater intrusion into the alluvial aquifer near Brinkley, Arkansas, 1984
E. E. Morris, W. V. Bush
1986, Water-Resources Investigations Report 85-4322
An approximate area of 56 sq mi of the alluvial aquifer just north of Brinkley, Arkansas, has been contaminated by saltwater (chloride concentration > or = 50 mg/L) intruded from underlying aquifers. The contamination was mapped from water quality data for 217 wells. Saltwater problems appear to have spread rapidly...
Metallogenic map of volcanogenic massive-sulfide occurrences in New Mexico
J. M. Robertson, M.S. Fulp, M.D. Daggett
1986, Miscellaneous Field Studies Map 1853-A
New Mexico volcanogenic massive-sulfide occurrences, which typically contain pyrite and pyrrhotite accompanied by variable amounts of base-metal sulfides and precious metals, are found within mainly subaqueous, compositionally bimodal metavolcanic successions of Early to Middle Proterozoic age that are exposed primarily in the north-central part of the state. Host rocks include...
Flood of September 12-13, 1982 in Gibson, Carroll, and Madison Counties, western Tennessee
Clarence H. Robbins, Charles R. Gamble, Roy H. Bingham
1986, Water-Resources Investigations Report 85-4037
Intense rainfall on September 12-13, 1982, caused severe local flooding along many streams in Gibson County in western Tennessee. The rainfall resulted from remnants of Hurricane Chris combining with a cool front moving across the western half of the State. A maximum 1-hr rainfall intensity of 3.3 in was recorded...
Potentiometric map of the lower Wilcox aquifer in Mississippi, fall 1982
Daphne Darden
1986, Water-Resources Investigations Report 85-4059
This potentiometric map is the second map of the lower Wilcox aquifer in a series of maps prepared by the U.S. Geological Survey in cooperation with the Mississippi Department of Natural Resources, Bureau of Land and Water Resources, delineating the potentiometric surface of the major aquifers in Mississippi. The potentiometric...
Hydrogeologic and water-quality characteristics of crystalline-rock aquifers of Archean and Proterozoic age, Minnesota
H. W. Anderson Jr.
1986, Water-Resources Investigations Report 86-4033
Five aquifers in crystalline rocks of Archean and Proterozoic age in Minnesota include in descending order the North Shore Volcanic, Sioux Quartzite, Proterozoic metasedimentary, Biwabik Iron formation and undifferentiated Precambrian aquifers. The North Shore Volcanic aquifer generally yields < 15 gal/min to wells from interflow sediments and fractures in the...
Configuration and hydrology of the Pre-Cretaceous rocks underlying the southeastern Coastal Plain aquifer system
Robert L. Wait, Marvin E. Davis
1986, Water-Resources Investigations Report 86-4010
An investigation was conduced to define the configuration and hydrology of the rock surface upon which the sand aquifers and confining beds of the Southeastern Coastal Plain aquifer system were deposited. The base of the Southeastern Coastal Plain aquifer system consists of crystalline rocks, saprolite, Paleozoic rocks, Triassic sedimentary rocks...
Ground-water availability in the Genesee River Basin, New York and Pennsylvania
John C. Kammerer, William A. Hobba Jr.
1986, Water-Resources Investigations Report 86-4048
New York State 's need to develop a groundwater management strategy for the protection of its aquifers led, in 1985, to a cooperative program between the U.S. Geological Survey and the New York State Department of Environmental Conservation, through the Genesee/Finger Lakes Regional Planning Council, to publish basinwide groundwater availability...
Evaluation of the U.S. Geological Survey's gaging-station network in Illinois
D. M. Mades, K. A. Oberg
1986, Water-Resources Investigations Report 86-4072
Data collected at 97 of the 176 gaging stations operated in Illinois during 1983 were used to describe rainfall-runoff processes, to monitor and forecast floods, and to monitor and regulate lake levels, discharge from reservoirs, or discharge of navigable streams. Stream-gaging stations on the Illinois River at Havana, East Branch...
Altitude of the freshwater-saltwater interface in a regionally extensive coastal plain aquifer of Mississippi, Alabama, and Georgia
Donald J. Strickland, Gary L. Mahon
1986, Water-Resources Investigations Report 86-4058
Geophysical well logs from over 150 oil test and water wells in Mississippi, Alabama, and Georgia were examined and calculations of the dissolved solids concentration in ground water were made using the spontaneous potential deflection as a measure of ionic activity. The values derived from these calculations were used to...
Water level and saturated thickness maps of the alluvial aquifer in eastern Arkansas, 1984
Maria Plafcan, Joe Edds
1986, Water-Resources Investigations Report 86-4014
The Mississippi River Valley alluvial aquifer, is a major source of water for most of eastern Arkansas. Agriculture is largely dependent on the aquifer as approximately 3.3 billion gallon per day are withdrawn for that purpose. Much smaller withdrawals also occur for industrial, public supply, and domestic use. The purpose...
Divisions of potential fracture permeability, based on distribution of structures and lineaments, in sedimentary rocks of the Rocky Mountains-High Plains region, Western United States
Maurice E. Cooley
1986, Water-Resources Investigations Report 85-4091
The principal map show geologic structures and lineaments that indicate fracture traces in sedimentary rocks in all or parts of Arizona, Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, Utah, and Wyoming.  Fractures associated with geologic structures and lineaments may affect the potential fracture permeability of consolidated rocks.  Divisions...
Ground-water availability in the Black River Basin, New York
Roger Milton Waller
1986, Water-Resources Investigations Report 86-4040
There are three maps in this set, which were prepared in 1966-68 as part of a study on the water resources of the Black River basin in cooperation with the New York State Department of Environmental Conservation. The data presented on the maps show well locations, well yield from bedrock...
Generalized potentiometric surface of the Catahoula aquifer in central Louisiana, 1980
Angel Martin Jr., Charles D. Whiteman Jr.
1986, Water-Resources Investigations Report 86-4059
Generalized contours of the altitude of water levels in wells completed in the Catahoula aquifer in central Louisiana, are illustrated by this map. Most water level measurements used in compiling the map were made in 1980; however, in parts of the State where water levels from 1980 were unavailable and...
Geologic implications of Paleozoic and Mesozoic paleontology and biostratigraphy, Blue Mountains province, Oregon and Idaho
Howard C. Brooks
T.L. Vallier, editor(s)
1986, Professional Paper 1435
This volume contains, besides the present review, seven papers on the biostratigraphy of pre-Tertiary rocks in the Blue Mountains province. Geologic implications of the faunal data are discussed in the context of terrane analyses. Most of the authors agree that the pre-Tertiary rocks of this province were formed in a...
