Geology
Geologic research conducted at the center encompasses a wide range of topics including bedrock geology, igneous processes, tectonics, surficial geology, potential for critical minerals and metallic resources, and field-based research which assesses the oil and gas resources of Alaska’s North Slope. Geologic research helps inform land use decisions and mitigate hazards.

GIS Prospectivity Analysis for Critical Minerals in Ore-Forming Systems in Alaska
Alaska is dominated by a history of tectonic events that foster mobilization and concentration of a wide variety of mineral commodities that are critical to the US economy and are vital to national defense, renewable-energy, and emerging electronics technologies.
Tectonic and Metallogenic Evolution of the Yukon-Tanana Upland, Alaska
The Yukon-Tanana upland in eastern interior Alaska is a geologically complex block containing deposits of base-metal, platinum-group-element, and gold-silver-copper mineralization. It also hosts numerous mineral systems that are known or suspected to contain critical minerals.
Petrology, Tectonic Setting, and Potential for Concentration of Rare Earth Elements (REE) and High Field Strength Elements (HFSE) in the High-K Darby and Kachauik Plutons, Seward Peninsula, Alaska
One of the geologic environments that host rare earth and other critical and strategic element deposits are alkaline intrusive rocks.
Metallogeny and Tectonics of the Lake Clark and Neacola Mountains Region, South-central Alaska
Alaska hosts a well-documented belt of ore deposits that lies roughly parallel to the Alaska Range, beginning at the Alaska Peninsula in the southwest, continuing up through the Fairbanks Mining District in the north, and curving back into the Tintina Gold Belt on its eastern end. Known mineral prospects and occurrences include porphyry copper, intrusion-related gold, volcanogenic massive sulfides...
Alaska Technical Data Unit - Field Records Archives
This project is designed to collect, inventory, preserve, and make available the records of USGS geologic and minerals work in Alaska. Materials are organized in two broad categories of records: (1) Project History files, which contain field notes, maps, and fossil reports; and (2) Geologic Subject files, containing unpublished materials, correspondence, and the Economic Minerals files. Access to...
Western Alaska Range Metallogeny and Tectonics
There are many different types of mineral deposits present in the Western Alaska Range: plutonic gold, porphyry copper-gold (Pebble prospect), epithermal gold, tin-silver skarns, sedimentary barite, mafic hosted nickle-platinum-group elements, uranium-thorium rare earth elements, and even a diamond prospect.
