From abstract "As part of the Department of Energy (DoE) National Uranium Resource Evaluation Program, LKB Resources, Inc. has performed a rotary-wing reconnaissance high sensitivity radiometric and magnetic survey, encompassing several 1:250,000 quadrangles in southwestern Arizona and southeastern California. The surveyed area consisted of approximately 9300 line miles. The radiometric data was corrected and normalized to 400 feet terrain clearance. The data was identified as to rock type by correlating the data samples with existing geologic maps. Statistics defining the mean and standard deviation of each rock type are presented as listings in Volume I of this report. The departure of the data from its corresponding mean rock type is computed in terms of standard deviation units and is presented graphically as anomaly maps in Volume II and as computer listings in microfiche form in Volume I."

This is an aerial reconnaissance survey of several Colorado and Arizona quadrangles.

From abstract: As part of the Department of Energy (DoE) National Uranium Resource Evaluation Program, LKB Resources, Inc. has performed a rotary-wing reconnaissance high sensitivity radiometric and magnetic survey of the Marble Canyon quadrangle NJ 12-11 located in northern Arizona. The surveyed area consisted of approximately 3,246 line miles.

This document contains maps and surveys analyzing the Marble Canyon quadrangle.

From Introduction: "Uranium has been discovered in fluvial quartz-pebble conglomerates in most of the Precambrian shield areas of the world, including the Canadian, African, South America, Indian, Baltic, and Australian shields. Occurrences in these and other areas are shown in Figure 1.1. Two of these occurrences, the Huronian supergroup of Canada and the Witwatersrand deposit of South Africa contain 20-30 percent of the planet's known uranium reserves (Nininger, 1974). Thus it is critical that we understand the origin of these deposits and develop exploration models that can aid in finding new deposits."
