Geologic structures

Type of structure Regional
Structure description Junction Between Ophiolite Belt And Zone Of Major Faults

Controls for ore emplacement

  • Contact Between Gabbros And Peridotites.

Comments on the geologic information

  • DEPOSIT OCCURS IN A COMPLEX ZONE OF CONTACT BETWEEN GABBROS AND PERIDOTITES. THE GABBRO INTRUSION IS CUT BY DIKES GENETICALLY ASSOCIATED WITH THE MINERALIZATION, AND HAS A COMPLEX EN ECHELON STRUCTURE WITHIN THE PERIDOTITES. ZONES OF INTENSE HYDROTHERMAL ALTERATION OCCUR PRIMARILY IN THE GABBRO AND ALONG THE GABBRO-PERIDOTITE CONTACTS. THE ORE BODIES OCCUR WITHIN THE ALTERED ZONES AND CONSIST OF QUARTZ VEINS AND QUARTZ CARBONATE VEINLETS WITH ABUNDANT SULFIDE MINERALIZATION. PRINCIPAL MINERAL ASSOCIATIONS INCLUDE 1) QUARTZ - SERICITE - PYRITE 2) QUARTZ - BREUNNERITE - PYRITE - ARSENOPYRITE 3) QUARTZ - MARCASITE - ARSENOPYRITE - SULPHOANTIMONITE - TELLURIDE 4) QUARTZ ANTIMONITE 5) LATE QUARTZ - CARBONATE. NATIVE GOLD IS WIDELY DISTRIBUTED AND MOST COMMONLY ASSOCIATED WITH TELLURIDES OF BISMUTH, NICKEL, SILVER, SULPHOANTIMONATES OF LEAD, AND SULPHOARSENIDES. THE ZOD DEPOSIT IS NOT A TYPICAL NEAR-SURFACE DEPOSIT AND MAY HAVE FORMED IN A SOMEWHAT DEEPER ENVIRONMENT TRANSITIONAL
  • TO NEAR SURFACE.
