Report discussing the contact and weathering of the Burro Canyon formation shales and Dakota sandstone as well as other connections of the Burro Canyon formation.

The following report covers measurements of electrical resistivity and dielectric constant that were made on parts of 27 cores from the Morrison formation in the Colorado Plateau uranium province as part of a program to obtain basic data on the physical properties of the rock in and near uranium-mineralized zones.

The following report describes the petrography of uranium-bearing carbonaceous shale and a non-uranium-bearing impure coal from two of the drill cores that were used to explore the underground extent of the east-central part of the Goose Creek district.

From abstract: "The Crevasse Canyon formation and Point Lookout(?) sandstone of Late Cretaceous age and the Baca and Datil formations of Tertiary age were mapped in an area of 168 square miles in the upper Alamosa Creek Valley along the northern edge of the Datil Mountains, Catron County, N. Mex. The investigation was made to determine the potentialities of the area for producing uranium and to learn the geologic controls for the concentration of uranium."

From introduction: The purposes of this paper are to tabulate and discuss the results of a number of complete disequilibrium analyses, to illustrate a proposed classification of disequilibrium patterns, to study these disequilibria as clues to the understanding of the geochemical history of the samples and of the deposits, and to point out some of the difficulties when simply comparing radioactivity and chemical uranium assays for interpreting equilibrium or disequilibrium in samples.
