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.



Our center has several laboratories, ranging from geophysics to geochemistry to spectroscopy to scanning electron microscopes.

Center Laboratories

Science 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:


Geophysics and Spectroscopy

Economic and Framework Geology

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.

Tungsten skarn potential of the Yukon-Tanana Upland, eastern Alaska, USA—A mineral resource assessment

Tungsten (W) is used in a variety of industrial and technological applications and has been identified as a critical mineral for the United States, India, the European Union, and other countries. These countries rely on W imports mostly from China, which leaves them vulnerable to supply disruption. Consequently, the U.S. government...

Pb-Pb and U-Pb dating of cassiterite by in situ LA-ICPMS: Examples spanning ~1.85 Ga to ~100 Ma in Russia and implications for dating Proterozoic to Phanerozoic tin deposits.

This paper investigates applicability of cassiterite to dating ore deposits in a wide age range. We report in situ LA-ICPMS U-Pb and Pb-Pb dating results (n = 15) of cassiterite from six ore deposits in Russia ranging in age from ~1.85 Ga to 93 Ma. The two oldest deposits dated at ~1.83–1.86 Ga are rare metal Vishnyakovskoe located in the...

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...
