A report recording the work done at ground-water test well A, which is one of the six wells that were put down especially to ascertain the direction and rate of groundwater movement beneath Yucca Flat

This report was formed after the study of the Nevada Test Site to examine parts of the thick miogeosynclinical section of the Paleozoic rocks and post-Paleozoic structural features for the sole purpose of determining the walking stops for future field trips to the test site.

This report briefly describes the geological data of the U12b.10 tunnel at the Nevada Test Site.

The following report presents the lithologic log of the description of the tuff penetrated by the U12g.06-U1 core drill hole located at the end of the U12g main tunnel at the Area 12, Nevada Test Site.

Introduction: "This report presents physical property analyses for 28 additional samples and is a supplement to Geological Survey Technical Letter: Area-12-1, which gave a brief summary of the geology, descriptive data on the tunnel, and X-ray, chemical, semiquantitative spectrographic analyses, and some physical properties determinations of samples collected in the U12g.01 tunnel."

This report presents the physical properties of tuff in the vicinity of the U12g.01 tunnel at the Nevada Test Site based off of two previous Technical Letters on the tunnel: Technical Letter: Area 12-1, and Technical Letter 12-1, Supplement 1.

From introduction: "This report presents physical property data of volcanic rocks underlying Rainier Mesa and vicinity in the northwest corner of the Yucca Flat area, Nevada Test Site."

This report summarizes the gravity data of the Area 12, Nevada Test Site.

"The surficial deposits of Yucca Flat, divided into eleven units, are shown at a scale of 1:48,000 (fig. 1A). Major rock types of the bordering bedrock areas are indicated, as are the lithologies of portions of the surficial units. The map explanation (fig. 1B) includes a description of the surficial units."

The following report summarizes the hydrologic data collected during the nuclear detonation, the Bilby event, that took place in the U3cn emplacement hole.

This report describes the simplified methods used to obtain the magnetic property data required to interpret an aeromagnetic survey of 5,000 square miles in the general area of the Nevada Test Site.

This report summarizes the stratigraphy, lithology, and physical properties studied in the UE12p#1 exploratory diamond drill hole at the Nevada Test Site.

The following report presents data from the exploration progress of central Nevada.

Abstract: "Drill hole UCe-18 was successfully logged with the U.S. Geological Survey-La Coste Romberg borehole gravity meter to a depth of 6,488 feet. That density increases with depth is apparent in both the alluvium and volcanic rock. The in situ density of the alluvium measured by the gravity meter ranges from 1.77 to 2.34 gm/cc; the lake beds beneath the alluvium have a density of 2.22 gm/cc; and the rhyolitic rocks range in density from 2.26 to 2.47 gm/cc. The average density determined from the borehole gravity meter data for the alluvium plus the lake beds is 2.22 gm/cc and for the volcanic rocks is 2.35 gm/cc."

Abstract: "The Midi Mist (U12n.02) event produced rock spalling along bedding, joint, and fault planes in the U12n.02 and U12n.03 drifts. The spalling in the U12n.02 drift started at about construction station 12 + 75 and was continuous toward the W.P. Most of the spalling in the U12n.03 drift occurred between C.S. 0 + 00 and 7 + 00."

The following report summarizes the geophysical studies of the rocks made in the U12e.10 tunnel of the Nevada Test Site.

The following report describes the computer technique for tracing seismic rays in two-dimensional geological models in the state during the time this report was written, and presents some preliminary results.
