The authors would like to thank Rainer Newberry (DGGS) for review of this manuscript, and Michael Barerra (University of Alaska Fairbanks), Dylan Avirett and Angie Hubbard (DGGS Geologic Materials Center), and staff at the University of Arizona LaserChron Center for their contributions towards data collection, technical discussion, and other support. This project was funded by State of Alaska (SOA) general funds, SOA Capital Improvement funds, and the U.S. Geological Survey's Earth Mapping Resources Initiative (Earth MRI) under cooperative agreements GSG20AC00156 (Western Tanacross) and GSG21AC00336 (Taylor Mountain). The views and conclusions contained in this document are those of the authors and should not be interpreted as representing the opinions or policies of the U.S. Geological Survey. Mention of trade names or commercial products does not constitute their endorsement by the U.S. Geological Survey.
The Western Tanacross and Taylor Mountain project areas are of historical and current interest for the potential development of precious metals, base metals, and critical mineral resources. With this U-Pb geochronology dataset, our goals are to delineate the timing and character of igneous and tectonic events that may be linked to regional and local controls on mineralization and to characterize the regional source material of the area's metamorphic terranes.
