Geologic map of the Talkeetna Mountains C-4 Quadrangle and adjoining areas, central Alaska

Description

Geologic map of the Talkeetna Mountains C-4 Quadrangle and adjoining areas, central Alaska, Preliminary Interpretive Report 2015-6, presents 1:50,000 scale geologic mapping of approximately 450 mi2 of the Talkeetna Mountains region of central Alaska. The project area contains significant exposures of Late Triassic mafic volcanics and gabbro sills that have been the focus of region-wide exploration for the Strategic and Critical platinum-group elements (PGEs). The area also exposes numerous inactive and possibly active faults which project through the area of proposed hydropower development. The resulting geologic map offers an improved understanding of the geology, structural history, and mineral potential of the area. The complete report, geodatabase, and ESRI fonts and style files are available from the Alaska Division of Geological & Geophysical Surveys website: http://doi.org/10.14509/29470.
