Subject category Comment text
Deposit CHROMITE IS CONCENTRATED IN PARALLEL BANDS 0.25-2 IN. THICK (AVG 1 IN. THICK), IN A FEW PLACES FORMING LENTICULAR BODIES. LARGEST LENS OBSERVED WAS 5 FT LONG AND 4 IN. THICK. MASSIVE CHROMITE SEEN IN STOCKPILE INDICATES SOME LENSES MAY HAVE BEEN 10 IN. THICK. THE CHROMITE BANDS ALTERNATE WITH LAYERS OF SERPENTINITE. MOST CHROMITE BANDS TERMINATE AGAINST AND ARE OFFSET BY SMALL CROSS FAULTS STRIKING N15W, DIPPING 50NE.
