Comments on the geologic information

  • 2 TYPES OF BAUXITE FOUND, COLLUVIAL AND REMANENT. STRAT SECTION: WHITE SAND [WHITE SAND SERIES] CLAY LENSES; BLEACHED CLAY (SED); TRANSITION; BAUXITE UPPER IN PISOLITE BAUXITE; TRANSITION ZONE (1.5 M); RESIDUAL CLAY-KAOLINITE BEARING; WEATHERED GRANITE. AFTER COVERING OF BAUXITE-FERRITE WITH SEDIMENTS OF THE WHITE SAND SERIES, THE BAUXITIZATION PROCESS CONTINUED AND THE BAUXITE-FERRITE BED INCREASED IN THICKNESS NOT ONLY AT THE COST OF THE UNDERLYING KAOLIN BUT ALSO OF THE CLAY FACIES OF THE WHITE SAND SERIES WHICH FORMS THE LOWER PART OF THIS SERIES.
