Field station locations and magnetic susceptibility data collected in 2020 and 2021 for the Western Tanacross project, Tanacross and Eagle quadrangles, Alaska

Description

DGGS Raw Data File 2022-3, Field station locations and magnetic susceptibility data collected in 2020 and 2021 for the Western Tanacross project, Tanacross and Eagle quadrangles, Alaska, presents locations, field descriptions of rocks, and magnetic susceptibility measurements from rock outcrops and/or hand samples collected during 1:100,000-scale bedrock geologic mapping of 2600 square miles within the Tanacross and Eagle quadrangles. The field areas for the Western Tanacross project are approximately 20 miles north and southwest of Tok. The project area is of current and historic interest for potential mineral resource development, including quartz vein Au mineralization, placer Au deposits, granite-hosted tin mineralization, and intrusion-related Cu-Au deposits. Prospects in the area include Triton, Tushtena, Taurus, and others. Much of the field area was mapped at 1:250,000 scale by the USGS in the 1960s. This project aims to produce more accurate and modern geologic maps and supporting datasets that will promote mineral resource exploration in eastern Interior Alaska.
