Geology, Geophysics, and Geochemistry Science Center
Home
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.
Laboratories
Our center has several laboratories, ranging from geophysics to geochemistry to spectroscopy to scanning electron microscopes.
Center LaboratoriesScience Branches
Our strong science portfolio integrates regional and economic geology with a broad range of geophysical, geochemical, analytical expertise. Our center has four scientific branches:
Economic and Framework Geology
Spatial Analysis and Data Management
All Laboratory Projects (regardless of branch)

The Unexpected Activity of Frozen Soils: New USGS Research Discovers Permafrost and Frozen Winter Soils May Be More Alive than Previously Thought
Newly published research indicates permafrost, or seasonally frozen, soils may be an overlooked source of greenhouse gases (GHG) prior to complete thaw, which could have implications for how thawing of this thick subsurface layer of soil will impact the global carbon budget and how future climate conditions are studied.

Geochemical and mineralogical properties of Boquillas Shale geochemical reference material ShBOQ-1
The ShBOQ-1 geochemical reference material is relevant to studies of the organic geochemistry and mineralogy of petroleum source rocks containing high concentrations of carbonate minerals and organic sulfur-rich, oil-prone marine organic matter. ShBOQ-1 is geochemically and mineralogically similar to the lower part of the Upper Cretaceous Eagle...

Mapping critical minerals from the sky
Critical mineral resources titanium, zirconium, and rare earth elements occur in placer deposits over vast parts of the U.S. Atlantic Coastal Plain. Key questions regarding provenance, pathways of minerals to deposit sites, and relations to geologic features remain unexplained. As part of a national effort to collect data over regions prospective...

Reconnaissance study of the major and trace element content of bauxite deposits in the Arkansas bauxite region, Saline and Pulaski Counties, central Arkansas
The Arkansas bauxite district, which comprises about 275 square miles (710 square kilometers) of central Arkansas, produced an order of magnitude more bauxite and alumina than the other bauxite districts in the United States combined. Bauxite was mined in the region continuously from 1898 to 1982. These bauxites are laterite deposits, formed from...
