Deposit THE DEPOSIT EXTENDS FROM CARACOLLO TO ORURO, A DISTANCE OF APPROXIMATELY 30 KM. AT THE CORDEOR WORKINGS, THE LACUSTRINE DEPOSITS ARE MADE UP OF DETRITUS FROM PALEOZOIC ROCKS TO THE EAST. THE MINED CLAYS ARE PALE REDDISH BROWN TO LIGHT BROWN AND NONSWELLING. THE ORE UNIT HAS A BASAL LAYER OF FINE SAND THAT GRADES UPWARD INTO A 1.3 M THICK INTERVAL OF SILT AND CLAY THAT CONTAINS LESS THAN 2% ASH. THE CLAY-BEARING HORIZON IS UNDERLAIN BY A 30 CM THICK BED OF SANDSTONE WHICH IN TURN IS UNDERLAIN BY 1 M OF FLUVIAL CONGLOMERATE WITH A SANDY MATRIX.
