Comments on the geologic information

  • DIAGENESIS; FOLDING; LCRET-CEN; HMTT + GRNR; LMON; IRREGULARLY-SHAPED DEPOSIT COMPLICATED BY FOLDING AND FAULTING IN LCRET LIMESTONES; ORE BODY FOLLOWS BEDDING IN LI-MESTONES. MINERALIZED ZONE IS AN AVERAGE OF 8 M THICK, 3000 M- IN LENGTH, AND 325 M IN WIDTH. DEPOSIT IS SEDIMENTARY IN ORI-GIN AND RESULTED FROM EROSION, TRANSPORTATION, AND DEPOSITION -(MAINLY AS A CHEMICAL DEPOSIT) OF ULTRABASIC ROCKS, PERHAPS OP-HIOLITIC ROCKS OF THE SUBPELAGONIC ZONE (RF4). THEY UNCONFORM-ABLY OVERLIE JUR-TRI LIMESTONES, AND ARE IN TURN CONFORMABLY O-VERLAIN BY LCRET LIMESTONES.
