Appendices containing uranium occurrence reports for the Mesa Quadrangle in addition to tables of chemical analyses, petrographic reports, and analyses of stream-water and rock samples to accompany a report of U.S. uranium resources in Arizona.

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 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.
