Subject category Comment text
Deposit DIAMOND BEARING GRAVELS FORM 2 THIN UNITS. LOWER GRAVEL (DARK ORE) IS 5-10 CM THICK AND CONTAINS IRON CONCRETIONS, SILICIFIED SANDSTONE FRAGMENTS, VEIN QUARTZ FRAGMENTS, AND CLAY. THE UPPER GRAVEL CONTAINS VEIN QUARTZ, SILICIFIED SANDSTONE FRAGMENTS AND CLAY MATERIAL, BUT HAS NO IRON CONCRETIONS. NO KIMBERLITIC MATERIAL HAS BEEN FOUND IN THE GRAVELS. THE LOWER GRAVEL IS MIXED WITH ORGANIC MATERIAL. NO KIMBERLITIC MATERIAL HAS BEEN FOUND IN THIS AREA. THE DIAMONDS IN THE YOUNG SEDIMENTS ARE BELIEVED TO BE DERIVED FROM PALEO-PLACERS IN THE PREC SEDIMENTARY ROCKS OF PRE-RORAIMA AND UAIREN FORMATIONS. BRICENO M. (1985) ALSO INDICATED THAT THE RECENT DIAMOND-BEARING SEDIMENTS WERE DEPOSITED UNDER ARID CLIMATIC CONDITIONS.
