| Deposit | DEPOSIT IS MASSIVE SULFIDE LENS IN METARHYOLITE OR NEAR CONTACT OF METARHYOLITE AND GABBRO. THE SHAPE OF THE PIPE IS DUE TO: (1) THE OVERHANG OF THE GABBRO ABOVE THE 3000 - FOOT LEVEL, (2) THE CONTACT BETWEEN THE GABBRO AND TUFFACEOUS SEDIMENTS OR QUARTZ PORPHYRY, AND (3) THE ZONE OF PRONOUNCED FOLIATION. THREE LARGE ORE SHOOTS AND 2 SULFIDE PIPES ALSO ARE PRESENT. QUARTZ PORPHYRY IS REPLACED BY SULFIDES. |
| Deposit | AN UNDERGROUND FIRE BEGAN IN 1894 WHEN PART OF THE SULFIDE ORE BODY SLIPPED TO CAUSE FIRE-STARTING FRICTION; MANY RARE FIRE MIENRALS WERE FORMED DURING THE MORE THAN 30 YEARS THAT THE FIRE BURNED. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT |
