Comprehensive analytical methods (for example, geochronology, geochemistry, radiogenic and stable isotopes) are combined with geological observations to characterize mineralization and to relate it to the geological context and tectonic environment(s) in which it formed."

This work is integrated with geophysical and metallogenic tasks described below to provide comprehensive constraints on the tectonic evolution of the region and framework geological controls on its mineral endowment."

     "text": "This multi-year study focuses on the geologic, metallogenic, and geophysical framework of the broader Yukon-Tanana upland in east-central Alaska. The project builds on a strong legacy of previous and recent USGS work in eastern Alaska and involves close collaboration with the Alaska Division of Geological and Geophysical Surveys (DGGS) and Canadian counterparts in the Yukon Geological Survey and Geological Survey of Canada. The area of interest extends from the western Tanacross and Eagle quadrangles to the Fairbanks area. The area includes two producing gold mines, multiple mineral districts, and numerous deposits and prospects that are the focus of active mineral resource exploration. All known or suspected mineral systems in the region have the potential for associated critical mineral enrichments. This project coordinates with systematic geological mapping and geophysical surveys conducted by DGGS under the USGS Earth Mapping Resource Initiative so that we fully capitalize on all available resources and thoroughly characterize the tectonic, magmatic, structural, geochemical, isotopic, and metallogenic evolution of one of Alaska\u2019s important mineral belts."
