Gravity Survey of the Nevada Test Site and Vicinity, Nye, Lincoln, and Clark Counties, Nevada: Interim Report

Description: From introduction: The gravity survey of the Nevada Test Site and contiguous areas of southern Nevada and southeastern California has been made by the U.S. Geological Survey on behalf of the U.S. Atomic Energy Commission. The objective of this study is to delineate and interpret gravity anomalies and regional trends so that the configuration and depth of the buried erosional surface of the Paleozoic rocks may be determined.

Ground Water Test Well C, Nevada Test Site, Nye County, Nevada : a Summary of Lithologic Data, Aquifer Tests, and Well Construction

Description: From introduction: USGS is appraising the possibility, however slight, that the ground water beneath the Nevada Test Site, possibly contaminated by nuclear detonations, may carry radioactive fission products to places where they may constitute a public hazard.

Interim Geological Investigations in the U12b.08 Tunnel, Nevada Test Site, Nye County, Nevada

Description: From introduction: The geologic studies in the U12b.08 tunnel were conducted by the U. S. Geological Survey on behalf of the U. S. Atomic Energy Commission for the purpose of determining the pre-explosion chemical and physical properties of the tuffs exposed in the tunnel. These data will be used in evaluating the geologic effects of the explosion by comparison with similar post-shot geologic data.

Outline of Geology of the U12k and U12k.01 Tunnels, Area 12, Nevada Test Site

Description: From introduction: Descriptive data for the Ul2k tunnel system are summarized in table 1. The U12k and U12k.01 tunnels were driven in predominantly air-fall tuffs of the Grouse Canyon and Survey Butte Members of the Oak Spring Formation of- Miocene(?) or younger age. The base of the Grouse Canyon Member is exposed in the road cut 500 to 700 feet east of, and at the same approximate elevation as, the portal U12k tunnel. The contact of the Grouse Canyon Member with the younger Survey Butte Member… more
