Geologic information

Identification information

Deposit ID 10308400
Record type Site
Current site name Anikovik River

Geographic coordinates

Geographic coordinates: -167.63641, 65.50426 (WGS84)
Relative position Anikovik River is a southwest-flowing stream, about 7 miles long, whose mouth is at York on the Bering Sea about 9 miles east of Tin City. This locality is on the main drainage of the river, about 1.5 miles upstream from the mouth at York. This is locality 37 of Cobb and Sainsbury (1972). Cobb (1975) summarized relevant references under the name 'Anikovik R.'.

Comments on the geologic information

  • Geologic Description = Anikovik River's eastern tributaries have headwaters in Ordovician limestone of the York Mountains (Sainsbury, 1972) whereas the main drainage and western tributaries are in areas underlain by a thin-bedded, slaty metapelitic and metasandstone sequence of unknown but probable Paleozoic age locally intruded by altered mafic bodies. The USBM completed three churn-drill holes in a line across Anikovik River at this locality (Mulligan, 1959). Heavy mineral concentrates from the five feet of gravel encountered here contained chromite (in one hole; 0.23 pounds of chromite per cubic yard containing 48 % Cr2O3), pyrite, limonite pseudomorphs after pyrite, olivine, augite, apatite, cassiterite, and gold. The gravels contain only a trace of tin.
  • Age = Quaternary
