National Uranium Resource Evaluation: Durango Quadrangle, Colorado
From purpose and study: The Durango Quadrangle, southwest Colorado (Fig. 1), was evaluated to identify geologic units and to delineate areas that exhibit characteristics favorable for uranium deposits. Geologic environments were evaluated to a depth of 1500 m based on recognition criteria (Mickle and Mathews, eds., 1978) prepared for the National Uranium Resource Evaluation (NURE) program. A favorable environment, as defined for this program, is an environment that could contain at least 100 tons U308 in deposits with an average grade no less than 100 ppm U308 . Environments that did not meet the NURE criteria were categorized as unfavorable. Some of the subsurface and several areas of restricted access were categorized as unevaluated because insufficient data exist for proper evaluation.
