Subject category Comment text
Deposit ELONGATE PROSPECT IN NW PART OF MINE AREA PROVIDES GOOD EXPOSURE OF GEOLOGY. PROPYLITIZED, SILICIFIED ANDESITES. VOLCANICS CUT BY MAFIC DIKES AND A N25W SHEAR ZONE. QUARTZ VEINS PARALLEL THE SHEAR ZONE FORMING A SHEETED VEIN SYSTEM. SHEAR ZONE 10-30 FT WIDE. SLICKENSIDES WITHIN THE ZONE ARE STEEPLY INCLINED AND COATED BY FE OXIDES AND QUARTZ. THE QUARTZ VEINS ARE GENERALLY SUBPARALLEL AND NUMEROUS. MANY ARE EMPLACED ALONG BOTH HIGH AND LOW-ANGLE FRACTURES. MOST OF THE VEINS ARE VUGGY, OPEN-CENTERED FISSURE-TYPE. THE VEINS ARE COMPOSED OF WHITE MASSIVE-COMB AND SUGARY QUARTZ. SOME OF THE VEINS ARE STEEPLY INCLINED AND OTHERS ARE SHALLOW OR ALMOST HORIZONTAL. ON EAST SIDE OF TRENCH THERE IS A 1-2 FT WIDE MASSIVE TO VUGGY QUARTZ VEIN AND QUARTZ-VEINED BRECCIA WHICH DIPS ABOUT 45 TO THE EAST. THIS IS PROBABLY THE HEART OF THE MAIN PENNSYLVANIA VEIN. THE ANDESITES IMMEDIATELY WEST OF THE VEIN ARE IRON-STAINED AND LACED WITH QUARTZ VEINS AND VEINLETS WHICH ARE MOSTLY N-NW-STRIKING AND MORE
Deposit STEEPLY INCLINED THAN IS THE MAIN VEIN. RELATIVELY SMALL AMOUNT OF FE AND MN OXIDES IS ASSOCIATED WITH VEIN MATERIAL, AND IN GENERAL THE QUARTZ CONTAINS ONLY A SMALL AMOUNT OF FINELY CRYSTALLINE PYR
