Map showing the distribution of minerals in the heavy-mineral concentrate of stream sediments in the Sierra Ancha Wilderness and Salome Study Area, Gila County, Arizona

Reconnaissance geochemical and mineralogical sampling was done in the Sierra Ancha Wilderness and Salome Study Area during April and May 1978. This map shows the distribution of chalcopyrite, florite, galena, scheelite, and lead-rich iron oxides in the nonmagnetic fraction of the heavy-mineral concentrate of stream sediment samples collected during the reconnaissance study.
