Alaska Earth Mapping Resources Initiative (Earth MRI)

Our objective is to provide a strategic framework for planning, coordination, and execution of the USGS Earth Mapping Resources Initiative (Earth MRI) in Alaska. Earth MRI aims to improve knowledge of the U.S. geologic framework through new geological and geophysical mapping and to identify areas that have the potential to contain undiscovered critical mineral resources.

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...

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.

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Project History files, which contain field notes, maps, and fossil reports; and (2) Geologic Subject files, containing unpublished materials, correspondence, and the Economic Minerals files.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...

Geologic Map of Alaska

In January 2016, the U.S. Geological Survey released the first ever digital geologic map of Alaska. This map reflects more than a century of work and provides a visual context for the abundant mineral and energy resources found throughout the state. The map also is available to use in three different formats: a professional GIS database, a public interactive version via a web browser, and an...

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.
