Ore body information

  • General form TABULOAR

Controls for ore emplacement

  • Rock Deformation Due To Thrusting & Normal Faulting

Comments on the geologic information

  • THE PROPERTY IS UNDERLAIN BY THE POGONIP ANTELOPE VALLEY LIMESTONE, THE EUREKA QUARTZITE, AND THE HANSEN CREEK DOLOMITE. ALL THREE ORDORICIAN UNITS ARE MINERALIZED AND THE AREA IS CUT BY NUMEROUS HIGH ANGLE FAULTS AND HAS BEEN OVERTHRUST FROM THE WEST. THE FLUORITE & BERYL GENERALLY OCCURS IN QUARTZ VEINS WITH SERICITE, HOWEVER ORE ALSO OCCURS AT THE QUARTZITE-CARBONATE CONTACT AND AS DISSEMINATIONS. (PAPKE, 1979)
