Geologic information

Identification information

Deposit ID 10308422
Record type Site
Current site name York Creek (West)

Geographic coordinates

Geographic coordinates: -167.11142, 65.56727 (WGS84)
Relative position York Creek is a north-flowing tributary to the Pinguk River. It heads on the continental divide and the north flank of Brooks Mountain, the highest part (2,898 feet elevation) of the York Mountains. Some of the headwater areas are in the contact zone of the Brooks Mountain granite stock. This location is on the west headwater fork of York Creek at an elevation of 510 feet. It is locality 47 of Cobb and Sainsbury (1972) and Cobb (1975) summarized relevant references under the name 'York Cr.'.

Comments on the geologic information

  • Geologic Description = The headwater area of York Creek, on the north flank of the Brooks Mountain area, includes the contact zone of the Brooks Mountain granite stock and a small granite plug in Ordovician limestone (Sainsbury, 1969, plate 1). Fine-grained, carbonaceous metapelitic rocks of uncertain but probable Paleozoic age are also present in this area and thermally metamophosed near granite intrusions. Three USBM churn-drill holes were completed at this locality (Mulligan, 1959, p. 6). The 7.5 to 12 feet of gravel overlying shale and limy shale bedrock contain a trace of tin per cubic yard. Minerals identified in the heavy mineral concentrate included pyrite, limonite pseudomorphs after pyrite, garnet, barite, tourmaline, scheelite, and powellite (Mulligan, 1959, p. 16).
