Subject category Comment text
Deposit NELSON AND RIESMEYER (1983) DESCRIBED DEPOSIT AS THICK PILE OF FELSIC VOLCANICS (RHYOLITE), VOLCANICLASTICS, AND CHERT LAYER FOLDED INTO WEST-PLUNGING SYNCLINE. RHYOLITE BELOW CHERT LAYER ON NORTH LIMB OF SYNCLINE STRONGLY ALTERED TO SERICITE-CHLORITE+/-TREMOLITE+/-GARNET+/-CORDIERITE AND CONTAINS DISSEMINATED CHALCOPYRITE-SPHALERITE+/-TETRAHEDRITE AND THE ZN SPINEL, GAHNITE. ALTERED SEQUENCE IN MINE AREA IS ABOUT 200 FT THICK, TRACEABLE FOR ABOUT 5000 FT TO WEST WHERE IT LOCALLY THICKENS TO OVER 1000 FT. DISTRIBUTION MAY REFLECT ALTERATION SYSTEM DEVELOPED ON FLANKS OF MASSIVE RHYOLITE PILE THAT WAS SUBSEQUENTLY DRAGGED OUT ALONG NORTH LIMB OF COMPLEX, DEFORMED SYNFORM.
