Comments on the geologic information

  • Geologic Description = This occurrence consists of beach placer deposits of ilmenite and titaniferous magnetite in a long spit covered by sand dunes up to 40 feet above water table. Fourteen drill and seven shovel samples were dug along this 20-mile section of beach (Berryhill, 1963). In the magnetic fraction, iron content ranged from 4.9 to 309.7 pounds per cubic yard and the titanium oxide content ranged from 1.2 to 70.2 pounds per cubic yard. In the non-magnetic fraction, titanium oxide content ranged from 0.8 to 8.5 pounds per cubic yard.
  • Age = Quaternary.
