Is satellite-derived bathymetry vertical accuracy dependent on satellite mission and processing method? Is satellite-derived bathymetry vertical accuracy dependent on satellite mission and processing method?
This research focusses on three satellite-derived bathymetry methods and optical satellite instruments: (1) a stereo photogrammetry bathymetry module (SaTSeaD) developed for the NASA Ames stereo pipeline open-source software (version 3.6.0) using stereo WorldView data; (2) physics-based radiative transfer equations (PBSDB) using Landsat data; and (3) a modified composite band-ratio...
Noble and base metal distribution and processes affecting ore tenors in the disrupted lower stratigraphy of the Stillwater Complex, USA Noble and base metal distribution and processes affecting ore tenors in the disrupted lower stratigraphy of the Stillwater Complex, USA
Exploration continues for contact-style Ni-Cu sulfide and chromitite-associated PGE mineralization in ultramafic rocks of the Stillwater Complex. At the Iron and Chrome Mountain areas, massive sulfides occur along the complex’s footwall contact and anomalous concentrations of PGE+Au are associated with the three lowermost chromitite seams. Southeast of Chrome Mountain, magmatic layering...
Estimation of the accessible and useful resource base for electric-grade enhanced geothermal systems (EGS) resources of the Great Basin, USA Estimation of the accessible and useful resource base for electric-grade enhanced geothermal systems (EGS) resources of the Great Basin, USA
Scientists with the U.S. Geological Survey (USGS) recently completed a provisional assessment of the electric-grade geothermal resources associated with the low-permeability geologic formations of the Great Basin, USA, where resources are assumed to be accessible using enhanced geothermal systems (EGS) technologies (i.e., the engineering of sufficient permeability to facilitate efficient...

Large Magmatic Systems for Minerals
This project continues work on large magmatic systems in the U.S., where critical mineral commodities important to clean energy technologies can be concentrated. Modeling of large mafic intrusion extents will continue, and new geophysical methods will be applied to improve understanding of magmatic systems.
Life Cycle of Critical Minerals: A Balanced Approach to Meeting Our Nation's Resource Demands
Critical minerals are essential to the Nation’s economy and security. Demand for critical minerals is increasing, and it is essential to balance the societal need for these minerals with efforts to understand the effects of mining on other natural resources and to develop techniques to minimize these effects. The USGS Minerals Resources Life Cycle Integrated Science Team (IST) focuses on the life...

Geology of the eastern Piedmont and upper Coastal Plain along the Fall Zone, Virginia to Georgia
This USGS NCGMP Project aims to fill the void in geologic map coverage along the Fall Zone from southeastern Virginia to central Georgia, for critical mineral research, earthquake hazards, and interstate correlation. We are also forging strong cooperative ties within the NCGMP by combining resources across all three Program components by supporting Virginia Energy (Virginia Geological Survey), the...
