Beach sands of Recent age which have accumulated in shallow water adjacent to the present shore of Morrison Beach, Kangaroo Island, have a heavy mineral content of 0.31%. The recently completed drilling programme has defined a sequence of fine to medium grained quartz sands, pebbly sands and a shell bed above a continuous stratum of clay. The heavy mineral content of 0.31% is confirmed though present estimates are generally lower than those previous determined for rutile (19%), zircon (36%) and kyanite (10%); the remainder comprises opaque iron oxides, garnet and tourmaline. The 'light' fraction comprises quartz sand, quartzite pebbles and shell fragments. Except for small areas adjacent to the present shore and fringing a stranded shore line there are no concentraticns of heavy minerals and the deposits are fairly uniform throughout. Reserves of sand are now estimated at 70 million cubic yards; 52,000 tons of rutile and 91,000 tons of zircon.
