| Location and accuracy | This site represents 5 miles of beach placer deposits on the northwest coast of the Alaska Peninsula extending for approximately 5 miles southwest of Franks Lagoon onto the Port Moller 1:250,000-scale map sheet (Cobb, 1973: B-1374, locality 3; MacKevett and Holloway, 1977, locality 4). The maps site is plotted at Franks Lagoon. |
Geologic descriptionThis occurrence consists of beach placer deposits of magnetite and titaniferous ilmenite in well-developed sandy spits extending 5 miles southwest of Franks Lagoon. Berryhill (1963) collected 11 auger samples and a few shovel samples along this 5-mile section of beach. These samples were screened, tabled, and run through a magnetic separater. The magnetic fraction contained 1.1 to 191.4 pounds iron per cubic yard and 0.3 to 42.2 pounds titanium oxide. The non-magnetic fraction contained 0 to 10.3 pounds per cubic yard titanium oxide. | |
