From to the files: To date, all the mineralization seen in the Monument Valley area in the Shinarump formation has been in scour channels. The mineralized rock occurs at or near the bottom of the channel. On Hoskinnini Mesa, all the channels examined to date contain some mineralized material. Channels observed may in some cases contain copper without apparent uranium mineralization; others definitely exhibit copper-uranium mineralization.

From abstract: This paper is primarily a progress report on studies designed to accumulate geologic data that will aid in our understanding of the localization and the genesis of uranium deposits in the Dripping Springs quartzite.

Preliminary recommendations are presented for drilling the area on a 1,000-foot grid to provide final elevation of the East Carrizo mining district.

From introduction: The purpose of this paper is to present the geologic facts which have been discovered thus far about the Lukachukai area and to draw conclusions about uranium mineralization. Basic data of general nature are included to facilitate the work of future geologists in this area who may find the information applicable to new ideas.

Report issued by the U.S. Bureau of Mines discussing asbestos mining and production in Arizona. As a supplement to a previous report, 18 additional Arizona mining districts are presented and described. This report includes tables, maps, illustrations, and photographs.

From introduction: A rapid appraisal of the carnotite resources of the Salt Wash sandstone member of the Morrison formation in the Carrizo Mountains area was undertaken by the U. S. Geological Survey late in 1951 in connection with its current project of geologic mapping of the area. Though brief and preliminary, this report provides a summary of production trends and estimated reserves in the area and indicates as far as possible the total potential of the area as a source of uranium. This information may be helpful in planning new milling facilities or other measures to encourage a higher rate of production.

Map of the area surrounding the census-designated place of Beclabito, San Juan County, New Mexico showing mine locations and mineralized rock exposures by geologic period, along with the location of triangulation stations with their elevation.

Map showing uncontrolled structure contours of the Beclabito Dome Area, Shiprock District, Arizona-New Mexico. The Salt Wash-Bluff contact was spotted on aerial photographs as a basis for the construction of the uncontrolled structure contour map

Abstract: Reconnaissance mapping in the Ruby Quadrangle, Arizona, indicates the existence of a complex assemblage of volcanic rocks and associated sediments, divisible into a younger and older series.

Report issued by the Bureau of Mines over studies conducted on the geologic factors related to block-caving. The results of the study are presented. This report includes tables, maps, and illustrations.

A report about the U. S. Geological Survey's program about uranium investigations and geologic mapping in the Monument Valley area, Arizona. A resource appraisal of the area was an inherent part of the program, and is detailed in this report.
