Comments on the geologic information

  • COUNTRY ROCK: TERTIARY EXTRUSIVE AND INTRUSIVE ROCKS OVERLYING JURASSIC VOLCANO-SEDIMENTARY TERRANE. JURASSIC ROCKS CONSIST OF FOLDED SEQUENCE OF STRONGLY CHLORITIZED ANDESITES INTERBEDDED WITH ORTHOQUARTZITES AND METAMORPHOSED LIMESTONES. EARLY TERTIARY (PALEO-EO) ANDESITES AND TRACHYANDESITES HAVE BEEN BLOCK-FAULTED INTO NW-SE TRENDING HORSTS AND GRABENS. MID-TERTIARY GRANITE CROPS OUT NE AND SE OF THE MINE AREA. LATE TERTIARY LITHIC TUFFS, IGNIMBRITES, AND RHYOLITE FLOWS TO THE N AND NE. YOUNGEST INTRUSIVE ROCKS ARE POST-GRANITIC APLITES AND DIABASES OF LATE TERTIARY AGE.
