Ore body information

  • General form IRREGULAR
    Width 1.52M

Controls for ore emplacement

  • Intersection Of Shear Zone And Reverse Fault

Comments on the geologic information

  • A FINE-GRAINED GRANITIC INTRUSIVE IN CONTACT WITH INTERBEDDED LIMESTONE & MARBLE WITH THE STRIKE OF THIS CONTACT GENERALLY S70E AND N70W, WITH DIP STEEP TO THE SOUTH. A LARGE THRUST FAULT BLOCK OF THE GRANITIC ROCK CRUSHED THE ONE TIME LIMESTONE BEDS MAKING THEM CHANNELS FOR THE TRANSPORTATION AND DEPOSITION OF SILICA AND TUNGSTEN BEARING SOLUTIONS ORIGINATING FROM THE GRANITIC INTRUSION. THIS DEPOSIT IS RELATED TO THE ADJACENT NEVADA SCHEELITE ORE BODY, AND MAY BE PART OF ROOF PENDANT PLUNGING NORTH.
