Geologic structures

Type of structure Local
Structure description Faults: Displacement Along Shear Zone Of Up To 50 Ft.

Controls for ore emplacement

  • Shear Zones; Dip Steeply Eastward, Trend In Two Directions, N 10 - 25 W And N 45 - 60 W. Feather Joints Along Walls Of Shear Zones Strike Due To North To N 10 E.

Comments on the geologic information

  • GEOL.DESC: MINE AREA IS UNDERLAIN BY QUARTZ - MICA SCHIST AND GNEISS, INTRUDED BY QUARTZ - DIORITE STOCK. METAMORPHIC ROCKS STRIKE NW, DIP STEEPLY EASTWARD. QUARTZ - BIOTITE SCHIST, MOST ABUNDANT ROCK IN AREA, BEDDING GENERALLY PARALLELS SCHISTOSITY. SOME CROSS - BEDDING IN META SANDSTONE BEDS. SCHISTOSITY STRIKES N 20 - 25 W, DIPS MORE THAN 80 E. DIKES OF QUARTZ - MUSCOVITE GNEISS CUT ACROSS SCHISTOSITY OF SCHIST. SMALL STOCK OF MASSIVE PORPHYRITIC QUARTZ - DIORITE WITH APLITIC APOPHYSES EXTENDING FROM STOCK ALONG SCHISTOSITY OF THE SCHIST. MASSIVE QUARTZ WITHOUT METALLIC MINERALIZATION OCCURS IN LENSES ALONG EASTERN MARGIN OF AREA, TRENDING N 45 - 60 W, DIPPING STEEPLY EAST ACROSS FOLIATION OF SCHIST.

Subject category Comment text
Deposit ELEVEN MINERALIZED VEIN ZONES ARE KNOWN IN THIS AREA. METALLIC MINERALS MAKE UP FROM 1 - 80 % OF THE VEINS; AVG. IS 5 %. EXPLORATION HAS SHOWN VEIN ZONES TO PERSIST A MINIMUM OF 300 FT. VERTICALLY, INDIVIDUAL VEINS RARELY EXCEED 40 FT. IN PITCH AND STRIKE LENGHT, THICKNESS VARIES FROM A FRACTION OF AN INCH TO 29 INCHES FOR VEINS. DEPOSITS FORMED BY REPLACEMENT OF SHEARED SCHIST BY QUARTZ, SILICATES AND SULFIDES.
