Great Basin Metallogeny and Regional Structure - New Interpretations of Magnetic and Gravity Data

This project incorporates new geophysical technologies developed at the Tucson office of the Geology, Minerals, Energy, and Geophysics Science Center over the last 20 years for assessing mineral deposits concealed by basin sediments. These technologies include: textural classification of magnetic and magnetotelluric data and methods to characterize bedrock/basement lithologies, improved...

Tellurium in Igneous-related Epithermal Precious Metal Deposits in Colorado and New Mexico

The project aims to improve our understanding of the causes of tellurium enrichment in epithermal precious metal deposits, and strengthen our ability to assess the Nation's tellurium deposits. Tellurium is used in solar panel technologies and is considered a critical mineral. Epithermal deposits of this type represent a prospective future source of tellurium.

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.

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...

Rare Earth Element Deposits in the Southeast Mojave Desert

In an effort to better understand domestic resource potential, the USGS is investigating the genetic relationship between rare earth element deposits at Mountain Pass, California and Music Valley (Pinto Mountains, California) and extend these studies across a 130-km long belt of alkaline Proterozoic rocks in the southeast Mojave Desert. Such a combined study would significantly improve our...

Continental Scale Geophysics — Integrated Approaches to Delineate Prospective Environments for Critical Metals

Regional geophysical data that are available over continental scales such as magnetic, gravity, and magnetotelluric data can provide a foundation towards identifying and understanding the footprints and deep plumbing systems underlying these important ore systems. Our project will use continental-scale geophysical data to map the locations of deep crustal and mantle structures that may act as...

Development and Validation of Hyperspectral Imager for Field and Lab Scanning

The Mineral Resources Program has advanced methods of imaging spectroscopy (hyperspectral remote sensing) that are now used routinely by the earth science and remote sensing communities for mineral mapping, soil quality mapping, hazard mitigation, and other terrestrial and planetary applications. The USGS is highly qualified to advance this technology based on its world class expertise in...

New Mineral Deposit Models for Gold, Phosphate Rare Earth Elements, and Placer Rare Earth Element-Titanium Resources

USGS Mineral Deposit Models are "an organized arrangement of information describing the essential characteristics or properties of a class of mineral deposits. Models themselves can be classified according to their essential attributes (for example: descriptive, grade-tonnage models, genetic, geoenvironmental, geophysical, probability of occurrence, and quantitative process models)." (Stoeser...

Multidisciplinary Studies to Image and Characterize the Mineral Resource Potential of the Midcontinent Rift, USA

This multidisciplinary study seeks to image and characterize the mineral resource potential of the Midcontinent Rift System. Combining various geophysical methods with detailed mapping and geochemical analyses will help to define the geographic extent of the Rift and clarify its geologic makeup and configuration.
