Petrogenesis and mineralization potential of spinifex komatiitic basalts in the Bradley Peak greenstone terrane, Wyoming Province Petrogenesis and mineralization potential of spinifex komatiitic basalts in the Bradley Peak greenstone terrane, Wyoming Province
Komatiitic volcanic rocks are important hosts of Ni sulfide mineralization and record early Earth evolution; however, those in the well-studied Archean Wyoming Province have received little attention. Here, we elucidate the timing and petrogenesis of the Bradley Peak komatiitic volcanic rocks using field and textural observations, geochronology, and geochemistry. Detrital and igneous...
Uppermost Oligocene and Miocene diatom biostratigraphy of Ocean Drilling Program Sites 682 and 688 from the Peru Margin Uppermost Oligocene and Miocene diatom biostratigraphy of Ocean Drilling Program Sites 682 and 688 from the Peru Margin
The diatom biochronology of ODP (Ocean Drilling Program) Holes 682A and 688E provides a detailed framework for refiningMiocene diatom zonation in the East Pisco Basin of southern Peru, establishing both a nearly complete offshore reference section and a correlation tool for the fragmentary onshore vertebrate-bearing deposits. This new biostratigraphic record documents a complete...
Origin of the high Pd/Pt ratio of the J-M Reef, Stillwater Complex Montana USA Origin of the high Pd/Pt ratio of the J-M Reef, Stillwater Complex Montana USA
The J-M Reef of the Stillwater Complex exhibits a high and consistent Pd/Pt ratio (~3.8). This ratio results from the equilibration of an immiscible sulfide liquid with a relatively high Pd/Pt silicate melt rather than an unusually Pd- and Pt-enriched parental melt. Numerical modeling suggests that the original silicate melt contained typical mantle-derived concentrations of Pd and Pt (...

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...
2024 Hurricane Helene Landslide Hazards
Hurricane Helene produced widespread and damaging landslides. The USGS is mapping landslides to support our partners. This page provides information about the extent and severity of landslide impacts. Hurricane Helene made landfall in Florida as a Category 4 storm on Thursday, September 26th, 2024. The hurricane continued across the southern Appalachian Mountains producing record rainfall. This...
