Geologic information

Identification information

Deposit ID 10307635
Record type Site
Current site name Unnamed (west of Icy Bay)

Geographic coordinates

Geographic coordinates: -141.83464, 59.99776 (WGS84)
Relative position This occurrence is along the logging road west of Icy Bay. The map site is about four-tenths of a mile west of where the logging road crosses Little River, in the north-central part of section 21, T. 22 S., R. 21 E., of the Copper River Meridian. This is sample locality 151 of Foley and others (1995). The map location is probably accurate to within one-half mile.

Comments on the geologic information

  • Geologic Description = Foley and others (1995) collected one sample at this location. It is probably from a raised beach on a Holocene marine terrace. Spiral concentrate from this sample contained less than 0.028 gram of gold per ton, 0.95 percent titanium, and 663 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. 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.
