Comments on the geologic information

  • CONTACT VEIN ALONG FAULT CONTACT BETWEEN THE QUARTZITE & CARBONATES. CARBONATES CONTAIN LENSES OF IRON OXIDE. BURT VEIN STRIKES N 45 W AND 65 SW IN THE QUARTZITE. SAMPLE FROM CONTACT ADIT CONSISTED OF DARK BROWN JASPERY GOSSAN AND SILICIFIED (RECRYSTALLIZED) QUARTZITE FROM THE DUMP. IN THE AREA OF THE SHAFTS THE DOMINANT ROCK TYPE IS A FINE-TO MEDIUM-GRAINED TAN-PURPLE QUARTZITE, DOLOMITE OR LIMESTONE, ALTERED TO A PUNKY MIXTURE OF CLAY AND IRON OXIDES, ALSO EXPOSED ALONG PORTIONS OF THE TRENCHES. THE TRENCHES FOLLOW A HIGHLY IRON-STAINED BRECCIATED ZONE 10-20 FT WIDE STRIKING N45E,DIPPING STEEPLY SE. THIS ZONE CONTAINS BROWN AND RED SILICEOUS (OR JASPERY) FE-RICH PODS AND LENSES. AT S END OF TRENCH, ALTERED LIMESTONE IS EXPOSED WHICH CONTAINS PODS AND VEINS OF GREY CALCITE. LIMESTONE AND QUARTZITE ARE EVIDENTLY JUXTAPOSED BY THRUSTING AT THIS SITE, AS THEY ARE IN OTHER PARTS OF THE DISTRICT, BUT HERE THE UNITS ARE ALSO JUXTAPOSED ALONG SEVERAL HIGH-ANGLE STRUCTURES.
