General comments

Subject category Comment text
Deposit DEPOSITS FORMED AT PLATEAU LEVEL OVER WIDE AREA HAVE BEEN DISSECTED BY RECENTLY UPLIFTED DENDRITIC CONSEQUENT STREAMS
Deposit PROTORE ZONE (C) CONSISTS OF LATERITIC MATERIAL SATURATED WITH AL HYDROSOLS WHICH CRYSTALIZE RAPIDLY TO GIBBSITE UPON DRYING. GIBBSITE NODULES ARE EVIDENT IN ROADCUTS OR SLUMPED SOIL ZONES, BUT ARE NOT PRESENT IN UNDISTURBED, WATER - SATURATED ORE ZONE. THIS IS CONFIRMED BY X - RAY DIFFRACTION TESTS (CATHCART).
