Geophysical Mapping of Geologic Systems Host to Critical Mineral Deposits, Southern Midcontinent, US
The objective of this project is to use high-resolution state-of-the-art airborne and regional ground geophysical methods to map an underexplored region of the southern Midcontinent that is important to economic and critical mineral deposits.
Geophysical Research and Development
The Geophysical Research and Development Project supported the development of new and existing geophysical techniques for addressing critical geological problems. Research conducted under this project included development of needed geophysical methods and software, development of new geophysical instrumentation, and applications of geophysical techniques to frontier areas of geology.
Geochemical Signatures and Environmental Impacts of Ore and Trace Mineralization in the Southern Midcontinent
The overall project objective is a comprehensive analysis of the natural and anthropogenic consequences of extensive ore and trace mineralization in the southern midcontinent of the U.S. with a focus on Missouri. This will be conducted at two scales: 1) landscape and 2) process-level. 1) Landscape scale using geospatial and machine learning techniques to combine multiple geochemical and geologic...
Iron Oxide-Copper-Cobalt-Gold-Rare Earth Element Deposits of Southeast Missouri—From the Ore Deposit Scale to a Global Deposit Model
The project main objectives are to: 1) geologically, characterize the setting and origin of the iron-copper-cobalt-gold-rare earth element deposits, and advance the knowledge of rare earth element and Co potential within iron oxide-copper-gold (IOCG) deposits of southeast Missouri, and 2) geophysically delineate and characterize the subsurface Precambrian geology using existing ground and new...
Synthesis of the Tectonic, Magmatic, and Metallogenic Evolution of the Midcontinent Rift System
The overall project objective is to develop a comprehensive synthesis of the tectonic, magmatic, and metallogenic evolution of the Midcontinent Rift System (MRS) through time by integrating geophysical, magmatic, and geochemical data and to create 3-D models of the rift over its evolution.
Mineville, Eastern Adirondacks – Geophysical and Geologic Studies
The USGS is using a set of advanced imaging and analysis tools to study the rocks within the eastern Adirondacks of upstate New York. The goal of these studies is to gain a better understanding of the geology and mineral resources in the area.
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 lineament...
Mineral Resource Assessment of U.S. Territories of the Caribbean Basin Archipelago including Puerto Rico, U.S. Virgin Islands and Adjacent Areas
Project objectives are to develop a modern probabilistic quantitative mineral resource assessment of Puerto Rico, U.S. Virgin Islands and adjacent geologically similar areas that examines the potential for minerals-based economic development and trade within the region.
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.
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...
