Geology, Geophysics, and Geochemistry Science Center
Welcome to the Geology, Geophysics, and Geochemistry Science Center (GGGSC) located in Lakewood, Colorado on the Denver Federal Center. At GGGSC, we apply expertise in geology, geophysics, and geochemistry to interdisciplinary efforts in support of the USGS mission to address the Nation’s important earth science issues, with an emphasis on mineral resources.

Brittle regime slip partitioned damage and deformation mechanisms along the eastern Denali fault zone in southwestern, Yukon
Rare bedrock exposures of the eastern Denali fault zone in southwestern Yukon allow for the measurement, sampling, and analyses of brittle regime fault slip data and deformation mechanisms to explore relations to far field, oblique plate motions. Host rock lithologies and associated slip surfaces show episodic damage zone‐related deformation and calcite ± hematite ± chlorite related hydrothermal f
The chlorine evolution of arc magmas and the crustal water filter
Degassing of water from magmatic systems is key to transporting metals from magmas to form ore deposits, but elements like chlorine, through the formation of anion complexes, can be important in solubilizing and mobilizing these metals into water-rich fluids. Reconstructing the Cl systematics of evolving magmas is thus an important step towards understanding the origins of ore deposits, but the ma
Spread and frequency of explosive silicic volcanism of the Carpathian-Pannonian Region during Early Miocene: Clues from the SW Pannonian Basin and the Dinaridesion during Early Miocene: clues from the SW Pannonian Basin and the Dinarides
Explosive silicic volcanism of the Carpathian-Pannonian Region (CPR) is increasingly recognized as the primary source of tephra across the Alpine-Mediterranean region during the Early and Middle Miocene. However, the tephrostratigraphic framework for this period of volcanic activity is still incomplete. We present new multi-proxy data from Lower Miocene ignimbrites and tephra fallout deposits from

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...
USGS Geochemical and Microanalytical Reference Materials Distribution
The Geology, Geophysics, and Geochemistry Science Center distributes geochemical reference materials and microanalytical reference materials. Reference materials are suitable for use in testing analytical methodologies and as quality control samples.
Persistent Science Challenges in Legacy Mine Land Site Management
The objective of this project is to provide targeted research results to benefit cooperators managing legacy mine land sites in the western U.S. by addressing three persistent scientific challenges: (1) determining the contribution of mining-related metal sources to water quality degradation when substantial natural background metal sources are also present; (2) adequately characterizing key...
