Comments on the geologic information

  • MINOR BASIN DEVELOPMENT; PGE-SULPHIDES + TELLURIDES + ARSENIDES; PYTT + PNLD + CLCP; THE PLATREEF IS LOCATED IN THE ROOIPOORT NORITE-ANORTHOSITE (CRITICAL ZONE), WHICH TRANSGRESSES ONTO FLOOR-ROCK LI-THOLOGIES IN A NORTHERLY DIRECTION.
  • INTENSE FOLDING, FAULTING, METAMORPHISM AND MOBILIZATION OF SULPHIDE; EPROT; RB/SR: 1.7-1.8 GA; PYTT + PNLD + PYRT + CLCP; THE ORE BODY COMPRISES AN IRREGULAR, MORE OR LESS CONTINUOUS SHEET OF SULPHIDE WITHIN THE FOLDED, CONFORMABLE BIOT-ITE SCHIST UNIT. THE SULPHIDES FORM MASSES AND VEINLETS IN TH-E SCHIST, AND TOGETHER WITH QUARTZ, PLAGIOCLASE, AND BIOTITE, -CONSITUTE A MATRIX FOR SMALL TO LARGE INCLUSIONS OF SCHIST, PE-GMATITE, AND SERPENTINIZED AND MINERALIZED PERIDOTITE. THIS D-EPOSIT APPEARS TO BE THE MOST INTENSELY DEFORMED AND METAMORPH-OSED OF THE THOMPSON BELT NICKEL DEPOSITS.
