Other items on this site that are directly related to the current dataset.
Purpose and Scope: "The McAllen and Brownsville Quadrangles, Texas (Fig. 1), were evaluated to a depth of 1500 m (5,000 ft) 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 investigation, are those that could contain uranium deposits of at least 100 tons U3O8 at an average grade not less than 100 ppm U3O8."
