Comments on the geologic information

  • Geologic Description = Bedrock in the area consists of folded and faulted Hunt Fork Shale that is locally cut by quartz and sulfide-bearing quartz-carbonate veins and veinlets. Cobble-sized pieces of rounded massive white barite, containing streaks and blebs of galena were found as float. The source of the float is unknown. In another gully 800 m to the northeast, lense-like quartz-calcite-siderite veins are confined to a 50 cm-wide zone that trends northwest. The veins contain minor chalcopyrite and trace galena. No zinc minerals were observed.
