Comments on the geologic information

  • Geologic Description = Foley and others (1995) collected two beach samples at this location. Spiral concentrates from these samples contained 0.452 and 1.552 grams of gold per ton, 1.10 and 1.49 percent titanium, and 695 and 1,630 ppm zirconium. Thomas and Berryhill (1962) collected reconnaissance beach samples (IB004, IB006-010) from the Icy Bay area that contained trace to small amounts of magnetite, ilmenite, chromite, zircon, rutile, garnet, sphene, xenotime, and gold. The magnetic fraction of their samples contained as much as 6.2 pounds of iron and 1 pound titanium oxide per cubic yard in the magnetic fraction. The non-magnetic fraction contained as much as 6.4 pounds, but mostly less than 2 pounds, of titanium oxide per cubic yard.
  • Age = Holocene.
