Geochemical data from samples collected in 2024 for the Chena and Steese projects, Big Delta, Circle, Fairbanks, and Livengood quadrangles, Alaska
Description
Geochemical data from samples collected in 2024 for the Chena and Steese projects, Big Delta, Circle, Fairbanks, and Livengood quadrangles, Alaska, Raw Data File 2025-17, presents major oxide and trace element geochemistry of igneous, metamorphic, and potentially mineralized rocks collected during the 2024 field season as part of the Steese and Chena projects. Geologists from DGGS conducted 1:100,000-scale bedrock geologic mapping across a 9,635 km2 (~3,720 mi2) area of the Yukon-Tanana Uplands in eastern Interior Alaska, encompassing portions of the Big Delta, Circle, Fairbanks, and Livengood quadrangles. A total of 2,024 samples were collected to support these projects, which are funded by the U.S. Geological Survey (USGS) Earth Mapping Resource Initiative (Earth MRI) program. The work contributes to the modernization of geologic mapping in the region and supports mineral resource exploration efforts in Interior Alaska.
