Comments on the geologic information

  • Geologic Description = This occurrence consists of narrow beach deposits of black sand which occur primarily along the strand line. The black sand forms thin veneers of surf-washed titaniferous magnetite, ilmenite, and pyroxene. To test the sands the U.S. Bureau of Mines (Berryhill, 1963) drilled 15 auger holes along 15 miles of beach. The holes varied from 3.4 to 9 feet in depth. The drill samples were analyzed for iron and titanium oxide.? the magnetic fraction contained 3.6 to 41 pounds of iron and 1.5 to 9.2 pounds of titanium oxide per cubic yard. The non-magnetic fraction contained 0.4 to 1.6 pounds of titanium oxide per cubic yard (Berryhill, 1963). Trace amounts of flour gold were recovered from two of the holes.
  • Age = Quaternary.

Comments on the workings information

  • Workings / Exploration = In 1963 the U.S. Bureau of Mines drilled 15 holes to test the titanium content of the black sands. The magnetic fraction contained 3.6 to 41 pounds of iron and 1.5 to 9.2 pounds of titanium oxide per cubic yard. The non-magnetic fraction contained 0.4 to 1.6 pounds of titanium oxide per cubic yard. Trace amounts of flour gold were recovered from two of the holes.
