Final report documenting a high-sensitivity airborne radiometric and magnetic survey of the Newark quadrangles including the survey description, specifications, data processing methods, interpretation methods, and regional geologic review.

Second volume of a report documenting a high-sensitivity airborne radiometric and magnetic survey of the Newark quadrangle including maps documenting geophysical and geochemical data, as well as magnetic, ancillary and radiometric data.

Final report documenting the statistical analysis of an aerial gamma-ray and magnetic survey of the Red River Area including the Ardmore, Sherman, Abilene, and Dallas quadrangles in north Texas and southern Oklahoma. Quadrangle-specific maps and data are published as separate volumes.

From addendum: Two types of analyses for uranium in the stream-sediment samples are presented. One split of the stream-sediment samples was sent to Resource Associates of Alaska's laboratory, where they were analyzed for U by the fluormetric method after acid extraction. This is the method employed for U by most laboratories. The completeness of uranium extraction unavoidably varies with the particular type of uranium-bearing minerals present and possibly with the amount of iron, manganese, and carbonaceous material present, which can interfere with the extraction. Analyses by the method are shown in the text and appendix columns with the designation "RAA."

From abstract: The geochemical dispersion of uranium has been investigated near sedimentary uranium prospects in eastern and north-central Pennsylvania.
