Bedrock-geologic map, Alaska Highway corridor, Tetlin Junction, Alaska to Canada border
Preliminary Interpretive Report 2019-3, Bedrock-geologic map, Alaska Highway corridor, Tetlin Junction, Alaska to Canada border, shows the distribution of bedrock units exposed at or near the surface in the corridor along the Alaska Highway in parts of the Tanacross A-1, A-2, A-3, and B-3 and Nabesna C-1, D-1, and D-2 quadrangles. It is the easternmost of three bedrock-geologic maps along the Alaska Highway corridor. It is part of a multi-year project conducted by the Alaska Division of Geological & Geophysical Surveys (DGGS) between 2006 and 2013. The project focused on investigating and reporting the geology and geologic hazards of the corridor. Bedrock units were mapped and structural elements were measured in the field; where bedrock units are covered by surficial units and vegetation, units were interpreted using airborne-magnetic and electromagnetic surveys published by DGGS in 2006. Rock names were assigned based on field and petrographic observations, modal-mineral percentages, and interpretations of geochemical data. The complete report, geodatabase, and ESRI fonts and style files are available from the DGGS website: http://doi.org/10.14509/30038.
