Geology of the salt deposits and the salt industry of northern Chile
George Edward Ericksen
1963, Open-File Report 63-31
The study of the salt deposits of northern Chile is a cooperative project of the Institute de Investigaciones Geologicas (IIG) of Chile and the United Nations Special Fund and is part of a mineral resources survey, undertaken by these two organizations, of selected regions of northern Chile, during 1960-1963. The...
Exploratory geophysical traverses in the Oakfield Hills area, Smyrna Mills Quadrangle, Maine
Martin Francis Kane, Randolph Wilson Bromery, Frank C. Frischknecht
1963, Open-File Report 63-71
Ground magnetic, gravity, and electromagnetic measurements in the Oakfield Hills area have delineated a series of steeply dipping, dikelike rock units with high apparent susceptibility, high density, and often high conductivity. The measurements were made to investigate the source of a 3000-gamma aeromagnetic anomaly. The rock units are apparently a...
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...

Investigations of the principal fluorspar districts of Mexico
Ralph Erskine Van Alstine, Samuel Estrada, Ernesto de la Garza
1963, Open-File Report 63-124
As a result of the increasing need for fluorspar, especially in North America, the Mexican fluorspar industry expanded greatly is the 8-year period, 1952-1960. Since 1956, Mexico has been the world's largest producer and exporter of this commodity. From 1956 through 1959 Maltice imported about 90 percent of the fluorspar...
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...
Uranium in sediments
John Nicholas Rosholt
1963, Open-File Report 63-117
An oceanographic approach is used to study the distribution of abnormal occurrences of uranium in sediments. The occurrences predominate in marine phosphorites, black marine shales, and deposits in terrestrial-fluvial sandstones and ancient conglomerites. In early Paleozoic times, marine shales accounted for the majority of uranium deposition. By the beginning of...
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...

Report on the operation of Barnaby, summer, 1948
Henry Faul
1963, Open-File Report 63-32
Barnaby is a self-contained truck-mounted unit for gamma-ray logging of diamond drillholes less than 200 feet deep. The radiation is detected by Geiger-Muller counter and the impulses are transmitted up a single-conductor shielded cable by a special circuit. At the surface the impulses are electronically counted and the average counting...
