A Gossan at the Blackbird Cobalt-Copper Mine
USGS scientist Art Bookstrom maps and samples a gossan, developed on tightly folded, mineralized, metamorphosed, and weathered banded siltite, exposed on the southwest rim of the Blacktail pit of the Blackbird cobalt-copper mine, in the Salmon River Mountains of east-central Idaho. The gossan is overlain by unconsolidated colluvial debris.
