Field station locations and magnetic susceptibility data collected in 2019 for the Eastern Tanacross Project, Tanacross and Nabesna quadrangles, Alaska

During the 2019 field season, geologists from the Alaska Division of Geological & Geophysical Surveys (DGGS) conducted 1:100,000-scale geologic mapping and sampling of a 1,900-square-mile area in the eastern Tanacross and Nabesna quadrangles. The area lies approximately 15 miles east of Tok and 12 miles north of Northway. The area is of present and historical interest for its potential mineral resources, including porphyry copper-molybdenum-gold, intrusion-related gold, volcanogenic massive sulfides, and rare-earth-element enriched mineralization. It encompasses prospects including Oreo, Ladue, Pushbush, Honks, Goodrich, and Mount Fairplay. The majority of the area was previously mapped at reconnaissance 1:250,000 scale by the USGS during the 1960s. The purpose of this project is to produce a more accurate and modern geologic map and supporting data that will promote mineral discovery in eastern Interior Alaska. This report provides locations, field descriptions of rocks, and magnetic susceptibility measurements from rock outcrop and/or hand samples throughout the map area. The data associated with this report are available in digital format as a comma-separated value (CSV) file. All files can be downloaded from the DGGS website: http://doi.org/10.14509/30268.
