_small.jpg) | Older specimen from the Creole Mine originally from an old Utah collection. I see Magnetite, Chalcopyrite, and thin acicular crystals of Actinolite. Calcite has been etched, dissolved with HCl. These are the specimens containing Bismuthinite normally found by etching the Calcite. I did not positively identify any in this specimen. I think the acicular crystals I saw were probably all Actinolite crystals. It is still uncommon material from Utah. ex Glenn Davidson collection. ex Lehigh Minerals specimen. ex Otto Reiter collection. |
