    U-Pb zircon geochronology of bedrock samples collected in the Eagle and Tanacross quadrangles, eastern Alaska

    Metadata Updated: September 8, 2023

    U-Pb zircon geochronology of bedrock samples collected in the Eagle and Tanacross quadrangles, eastern Alaska, Preliminary Interpretive Report 2023-2, presents uranium-lead (U-Pb) zircon ages from 50 igneous, sedimentary, and metamorphic samples collected during 2020 and 2021 in support of the Western Tanacross and Taylor Mountain bedrock-geologic mapping projects. These two projects encompass an area of ~2,600 square miles (~6,700 sq km) of eastern Interior Alaska including the Mosquito Fork, Dennison Fork, and Middle Fork of Fortymile River drainages. The majority of the Western Tanacross project area is located approximately 20 miles north of Tok, and a small portion is located to the southwest; the Taylor Mountain area is within a 50-mile radius of Chicken. Both 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. The data are available from the DGGS website: http://doi.org/10.14509/31013.
