Ground-water levels in observation wells in Oklahoma, 1956-1960
D.L. Hart Jr.
1963, Open-File Report 63-150
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 on a systematic basis records of water levels in selected observation wells. These water-level records: (1) provide an index to available ground-water supplies;...
Fluid impact craters and hypervelocity - high velocity impact experiments in metals and rocks
H. J. Moore, R.W. MacCormick, D. E. Gault
1963, Open-File Report 63-100
The impact phenomena of hypervelocity and high-velocity projectiles with rock and metal targets are being studied in a cooperative research program conducted by the U.S. Geological Survey and the Ames Research Center of the National Aeronautics and Space Administration. This paper deals with the comparison of: (1) fluid-impact craters produced...
Stratigraphic sections and correlation of beds in the Inyan Kara Group and Morrison Formation, north end of the Black Hills, Crook County, Wyoming, and Butte County, South Dakota
W. J. Mapel, C. L. Pillmore
1963, Open-File Report 63-88
Descriptions of 47 stratigraphic sections of the Ivan Kara Group and Morrison Formation are given for an area extending from bluffs on the west side of the Belle Fourche River in T. 56 N., R. 64 W., Crook County, Wyo., southeastward across the Bear Lodge Mountains to a point in...
Water levels in observation wells in Santa Barbara County, California, in 1962
K. S. Muir
1963, Open-File Report 63-103
Investigation of the ground-water resources of Santa Barbara County was continued during 1962 by the U. S. Geological Survey in cooperation with the Santa Barbara County Water Agency. Monthly water-level measurements were made in 201 wells, in 9 of which automatic water-level recorders were operated. Earlier measurements, covering the period...
Placer tin deposits in central Alaska
Robert Mills Chapman, Robert Roy Coats, Thomas G. Payne
1963, Open-File Report 63-15
Placer tin, in the form of cassiterite (Sn02) and (or) tinstone (fragments including cassiterite and some vein or rock material), is known or reported in deposits that have been prospected or mined for placer gold in four areas adjacent to the Yukon River in central Alaska, 120 to 240 miles...
Geologic Setting of the Hamme Tungsten District, North Carolina and Virginia
John Mason Parker
1963, Bulletin 1122-G
The Hamme tungsten district is in the eastern part of the Piedmont province, mainly in Vance County, North Carolina, but it extends a few miles into Virginia. The district is underlain by a central lenticular pluton of albite granodiorite that trends north-northeastward and is flanked on both sides by metamorphic...
Geology, hydrology, and water supply of Edwards Air Force Base, Kern County, California
Lee Carlton Dutcher, G.F. Warts Jr.
1963, Open-File Report 63-146
Edwards Air Force Base occupies the northern part of Antelope Valley, California. As a result of large-scale and increasing agricultural pumping in the valley, the net draft has exceeded the perennial supply since about 1930 and was about 170,000 acre-feet in 1951--at least three times the estimated yield. As a...
Fossils from lower part of the Mancos Shale, Disappointment Valley, San Miguel County, Colorado
John B. Reeside, Daniel R. Shawe
1963, Open-File Report 64-143
About 400 fossiliferous segments of drill core from the lower part of the Mancos Shale of Late Cretaceous age were collected by the author during an exploratory drilling program for uranium deposits conducted in 1955 and 1956 by the Geological Survey in the Disappointment Valley area, San Miguel County, Colo. "The samples were submitted to...
Preparation of water samples for carbon-14 dating
H.R. Feltz, Bruce B. Hanshaw
1963, Circular 480
For most natural water, a large sample is required to provide the 3 grams of carbon needed for a carbon-14 determination. A field procedure for isolating total dissolved-carbonate species is described. Carbon dioxide gas is evolved by adding sulfuric acid to the water sample; the gas is then collected in...
Principal lakes of the United States
Conrad D. Bue
1963, Circular 476
The United States has about 250 fresh-water lakes that are known to have surface areas of 10 square miles or more. Nearly 100 of these are in Alaska, and 100 in Minnesota, Wisconsin, Michigan, New York,, and Maine. Thirty-four fresh-water lakes, exclusive of the Great Lakes, are known to have maximum...
