| Deposit | VEIN QUARTZ OCCURS AS SPOTTY, STOCKWORK-LIKE VEINS IN QUARTZITES. THE VEINS CONTAIN LIMONITE BOXWORKS AND DRUSY LIMONITE-COATED CAVITIES. THE VEINS APPEAR TO BE TENSION-GASH FILLINGS IN BOUDINS OF QUARTZITE SURROUNDED BY PHYLLITE. SIMILAR VEINING WAS OBSERVED AT THE NEARBY GOLDEN AMETHYST MINE. THE COMPOSITIONAL LAYERING, AND FOLIATION TRENDS N60E, 30NW. THE STOCK-WORK-LIKE GASH FILLINGS OCCUR IN A QUARTZITE LAYER. DRUSY QUARTZ CAVITIES ARE COATED WITH MN OXIDE STAIN AND FE OXIDE STAIN. |
