Geology and hydrology of the Claiborne Group in western Tennessee
Gerald K. Moore
1965, Water Supply Paper 1809-F
The area of western Tennessee underlain by the Claiborne Group is about 7,200 square miles and lies on the east flank of the syncline that forms the Mississippi embayment. It includes the Mississippi Alluvial Plain and part of a dissected upland plateau. The Claiborne Group dips to the northwest at...
Geology and ground-water resources of Dane County, Wisconsin
Denzel R. Cline
1965, Water Supply Paper 1779-U
The purpose of the ground-water investigation of Dane County, Wis., was to determine the occurrence, movement, quantity, quality, and availability of ground water in the unconsolidated deposits and the underlying bedrock. The relationships between ground water and surface water were studied in general in Dane County and in detail in...
An evaluation of aquifer and well characteristics of municipal well fields in Los Alamos and Guaje Canyons, near Los Alamos, New Mexico
Robert L. Cushman
1965, Water Supply Paper 1809-D
The Jenkins-Whitesburg area includes approximately 250 square miles In Letcher and Pike Counties in the southeastern part of the Eastern Coal Field. In this area ground water is the principal source of water for nearly all rural families, most public supplies, several coal mines and coal processing plants, and one...
Plant microfossils of the Hazard No. 7 coal, Perry County, Kentucky
Robert M. Kosanke
1965, Open-File Report 65-89
The cooperative mapping program between the Kentucky Geological Survey and the U. S. Geological Survey has yielded a number of interesting and valuable by-products. As a part of the stratigraphic studies involving Carboniferous coal fields, R. M. Kosanke has been involved in a detailed analysis of spore floras from various...
Veins in the northern part of the Boulder batholith, Montana
D. M. Pinckney
1965, Open-File Report 65-123
About 20 miles north of Butte and extending nearly to Helena, is an area of 350 square miles containing hundreds of veins and altered zones. The bedrock of the area is 1) late Cretaceous volcanic rocks, forerunners of the Boulder batholith, 2) the Boulder batholith of late Cretaceous to early...
Ground-water levels in observation wells in Oklahoma, 1963-64
P.R. Wood
1965, Open-File Report 65-184
The investigation of the ground-water resources of Oklahoma by the U.S. Geological Survey in cooperation with the Oklahoma Water Resources Board includes a continuing program to collect records of water levels in selected observation wells on a systematic basis. These water-level records: (1) provide an index to available ground-water supplies;...
Water resources in the vicinity of municipalities on the west-central Mesabi Iron Range, northeastern Minnesota
R. D. Cotter, H. L. Young, L. R. Petri, C. H. Prior
1965, Water Supply Paper 1759-C
Additional supplies of water are available near the municipalities or the west-central Mesabi Iron Range. The largest sources are the ground-water aquifers in the Biwabik Iron-Formation and the stratified glacial drift. Areas of stratified drift that probably have good water potential have been outlined. Surface-water supplies are negligible in the...
Field determination of nanogram quantities of mercury in soils and rocks
Margaret Hinkle, Kam Wo Leong, F. N. Ward
1965, Open-File Report 65-71
A method for determining nanogram quantities of mercury in geological materials is based on the catalytic effect of mercury on the reaction of ferrocyanide with nitrosobenzene to produce a violet-covered compound whose intensity if proportional to the mercury present. The mercury is released by heating a sample of soil or...
