4,231 miles of high sensitivty airborne radiometric and magnetic data were gathered in southwestern Colorado. Data were collected on traverse lines 1/4 mile apart and on tie lines of approximately 6 mile spacing in five seperate detail areas primarily within the Montrose 1° x 2° sheet. All data were fully reduced and interpered by geoMetrics and are presented as six volumes in this final report.

The following report is the second volume discussing the detailed aerial gamma ray and magnetic survey results taken for the Montrose quadrangle. This report focuses on Area 2, a detail area in Colorado, and provides a detailed geologic summary, interpretation report, six gamma ray and one magnetic contour maps. geochemical analysis map, interpretation map, flight line map, individual corrected profiles, survey area histograms and statistical tables.

The following report is the first volume documenting the high sensitivity airborne radiometric and magnetic data taken during the month of April, 1980, by EG&G geoMetrics in the western areas of South Dakota. This volume contains survey description, specifications, data processing methods, interpretation methods, and regional geologic review.

This report is one part of the second volume containing data on the Nemo Detail area in South Dakota. This volume contains the detailed geologic summary, interpretation report, standard deviation maps, pseudo-contour maps, interpretation map, flight line and geologic base map, individual corrected profiles, computer map unit histograms and statistical tables.

Second volume of a final report documenting the results of an airborne radiometric and magnetic survey, including data displays and interpretation results for the Kantishna River quadrangle.

Supplementary data containing information on geology, drill sites, and sample locations to accompany a report on geology and uranium favorability in Alpine and Tuolumne Counties, California. Scale 1:48,000

From project objectives: The Sonora Pass region was identified by the U. S. Department of Energy (DOE) as a potential uranium resource area because of past uranium production at the Juniper Mine and reported high-grade occurrences in other buried fluvial channels which are Tertiary in age. The objective of the Sonora Pass drilling project was to obtain subsurface data that would increase the accuracy of uranium reserve estimates for the project area.

Photographs taken during a project to study the geology of the Sonora Pass Region in California. An index describing the images is on page143/144 of the accompanying report.

This report presents rock sample and uranium data examined from the Van Horn, Texas area. Over 300 rocks samples were analyzed for 30 elements.

The following report describes the quantitative methods developed to support the resource estimating procedures for obtaining distributions of uranium occurrence from estimates of geologic features.

"A collection of subprograms for the manipulation of random variables (normally and lognormally distributed) and the calculation of moments of sums and products of random variables. Also, a collection of subprograms for the determination of Pearson type and the manipulation of cubic spline approximations to Pearson Distribution functions." (from Title page)
