General comments

Subject category Comment text
Deposit ULTRAMAFIC BODY IS COMPOSED OF MEDIUM-GRAINED DUNITE CONTAINING LIGHT GREEN, FRESH, FRIABLE OLIVINE. THE DEPOSIT IS THICKLY INTERSECTED WITH SMALL FAULTS FILLED WITH HIGH-GRADE LIGHT-GREEN VERMICULITE. NEAR SOUTHERN EXTREMITY THERE IS A CONCENTRATION OF MASSIVE CHROMITE IN SMALL LENSES. MOST OF CHROMITE IS ON NORTHERN SIDE AS DISSEMINATES CRYSTALS IN THE GRANULAR OLIVINE. CROSS-FIBER ASBESTOS VEINS ARE UP TO 8 IN. WIDE
