The following report presents results of the Sonora Pass, California detailed geochemical survey. Field and laboratory data are presented for 15 groundwater and 701 stream sediment samples.

From introduction: Geodata International, Incorporated, conducted an airborne gamma ray and total magnetic field survey of a region of Northwest Texas which covered the Lubbock and Plainview Geologic Atlas Maps. The area shown on Figure 1 was surveyed from an aircraft using large-volume radiation detectors with computer-controlled airborne equipment. Each map line was flown in an east-west direction with an average length of 120 miles. A total of 47 map lines were surveyed spaced at 3-mile intervals beginning at latitude 33000' and ending at latitude 350

This report presents field and laboratory data for 567 groundwater samples and 560 stream sediment samples collected from the Fremont quadrangle in Nebraska and Iowa.

"Field and laboratory data are presented for 671 water samples from the Kantishna River Quadrangle, Alaska. The samples were collected by Los Almos National Laboratory; laboratory analysis and data reporting were performed by the Uranium Resource Evaluation Project at Oak Ridge, Tennessee."

"Field and laboratory data are presented for 1,416 water samples from the Limon Quadrangle, Colorado. 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."

"Field and laboratory data are presented for 397 water samples and 746 sediment samples from the Ekalaka Quadrangle, Montana. Uranium values have been reported by Los Alamos National Laboratory in Report GJBX-55(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." (Abstract)
