Economic information

Comments on the geologic information

  • REPORTED CALCITE-LIMONITE VEINS IN THE OVERLYING PERMIAN HUECO LIMESTONE. BANDED INTERGROWTHS OF BARITE AND SULFIDES SUGGEST THAT SOME BARITE IS PRIMARY. BARITE AND CALCITE ALSO CONTAIN TWO-PHASE (LIQUID-VAPOR) FLUID INCLUSIONS. FRAGMENTS OF SULFIDES AND SANDSTONE LOCALLY OCCUR IN (FAULT?) BRECCIA WITH A BARITE MATRIX. SANDSTONE IS LOCALLY SHEARED, SUGGESTING FAULT MOTION.
