Comments

Comment (Location): CENTER OF T. 35. IN INYO NATIONAL FOREST.

Comment (Geology): GEOL.DESC: HYDROTHERMAL DEPOSITS OF VEIN ORIGIN AT THE INTERSECTION OF THE VERTICAL MINERALIZED ZONES AND SCHIST. MINERALIZED ZONES STRIKE N 40 E AND ARE ESSENTIALLY VERTICAL. THEY ARE CHARACTERIZED BY GARNET, SOME OF WHICH IS TYPICAL SKARN, AND BY PYRITE, EPIDOTE, RHODONITE, RHODOCHROSITE, PIEDMONTITE (?) AND A GREEN MINERAL THAT WEATHERS TO A BLACK MANGANESE OXIDE (JOHANNSENITE?). THE RHODONITE IS IN A LOCALIZED ZONE, 2 TO 3 FEET WIDE, AND THE RHODOCHROSITE IN A SIMILAR ZONE ABOVE THE RHODONITE.
