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.

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.

Appendix containing tables to accompany a report on an aerial gamma ray and magnetic survey in the Raton Basin in Arizona and New Mexico.

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.

Supplementary data containing tabulated elemental concentration data in surface sediment and ground water samples, in addition to areal distribution maps, histograms, and cumulative frequency plots, and a user's guide to accompany a hydogeochemical and stream sediment reconnaissance report of the Grand Canyon 1° x 2° NTMS Area, Arizona.

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.

Data collected as part of the hydrogeochemical and stream sediment reconnaissance for the Silver City quadrangle, New Mexico including laboratory data on waters and sediments as well as field data.

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.
