A progress report regarding the stratigraphy of the Triassic and associated formations in part of the Colorado Plateau region. Concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

This investigation was made to determine whether a diamond drilling program is warranted in the search for ore, and to provide basic data to guide such drilling.

Discussing a reconnaissance examination of certain portions of the mountainous area in Gila and Pinal Counties, Arizona, undertaken to inspect accessible outcrops of Dripping Spring quartzite.

Second volume of a report documenting a high-sensitivity airborne radiometric and magnetic survey of the Gallup quadrangle including results of data interpretation, significance factor profile maps, stacked profiles, and histograms.

Second volume of a report documenting a high-sensitivity airborne radiometric and magnetic survey of the Shiprock quadrangle including results of data interpretation, significance factor profile maps, stacked profiles, and histograms.

The following report describes most of the localities examined in deposits of uranium-bearing minerals in Arizona where anomalous radioactivity was detected between 1950 and 1954.

Report discussing stratigraphic studies of the Triassic and associated formations in northern Arizona and southern Utah. The programs of study included are "(1) regional stratigraphic descriptions and correlation of units, (2) sedimentary structure studies, (3) pebble studies, and (4) sedimentary petrology."

From abstract: "Stratigraphic studies of the Triassic and associated formations have been made in southeastern Utah and adjoining parts of Colorado and Arizona. These studies have followed five principal lines of investigation: regional stratigraphy, sedimentary petrology, pebble studies, sedimentary structure studies, and lithofacies studies."

From Purpose and Scope: "The Mesa Quadrangle, Arizona (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits. Favorable environments, as determined by surface and subsurface investigations, are those that could contain uranium deposits of at least 100 tons (90 metric tons) U3O8 with an average grade not less than 100 parts per million (ppm) U3O8."

From abstract: This data report presents results of ground water and stream/surface sediment reconnaissance in the National Topographic Map Series (NTMS) Grand Canyon 10 x 20 quadrangle. Surface samples (sediment) were collected from 1013 sites.

Abstract: Field and laboratory data are presented for 405 water samples and 736 sediment samples from the Silver City Quadrangle, New Mexico; Arizona. Uranium values have been reported by Los Alamos National Laboratory in Report GJBX-69(78). The samples were collected by Los Alamos National Laboratory; laboratory analysis and data reporting were performed by the Uranium Resource Evaluation Project at Oak Ridge, Tennessee.

From abstract: Results of the Date Creek Basin detailed geochemical survey are reported. Field and laboratory data are reported for 239 stream sediment samples. Statistical and areal distributions of uranium and possible uranium-related variables are displayed. A generalized geologic map of the area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed.

From introduction: This final report .is organized in two logical sections: (a) Volume I, containing the survey description, specifications, data processing methods, interpretation methods, regional geologic review and regional survey results and (b) one volume, Volume II, for each of the three quadrangles covered by the Raton Basin Project Area. Each Volume II contains a 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.

From objectives and scope: Project objectives were to synthesize available geologic information; to determine favorability criteria; and to describe, appraise, and delineate favorable areas of the Dripping Spring Quattzite.

Abstract: Napier Drilling Company of Dallas, Texas drilled 53,998.0 feet for exploration purposes, under Contract No. AT(05-1)-256. This footage was drilled in 508 holes during the period from June 21, 1954 through May 13, 1955.

Abstract: A drilling program was conducted by the Atomic Energy Commission on Cove Mesa, Arizona to further develop uranium and vanadium ore reserves that are vital to the National Defense. The drilling was performed by the Minerals Engineering Company of Grand Junction, Colorado. Uranium and vanadium ore horizons are found in the Salt Wash member of the Morrison formation on Cove Mesa.

Abstract: Hunt's Mesa was examined on June 2 and 3, 1951, by the writer assisted by R. C. Cutter. Two channels were located and studied. Outcrops of the channels are mineralized, the mineralization being of the copper-uranium variety. There are indications that an appreciable quantity of ore can be found by exploration drilling. A program of 25,000 feet of wagon drilling is recommended.
