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)

DGMETA (version 1)—Dissolved gas modeling and environmental tracer analysis computer program
DGMETA (Dissolved Gas Modeling and Environmental Tracer Analysis) is a Microsoft Excel-based computer program that is used for modeling air-water equilibrium conditions from measurements of dissolved gases and for computing concentrations of environmental tracers that rely on air-water equilibrium model results. DGMETA can solve for the...

LA-ICPMS U-Pb dating reveals cassiterite inheritance in the Yazov granite, Eastern Siberia: Implications for tin mineralization
U-Pb dating of cassiterite and zircon from the Yazov granite (Transbaikalia region, Eastern Siberia, Russia) and cassiterite from spatially associated tin mineralization in the Tuyukan ore district in the Tonod uplift was conducted using in situ laser ablation inductively coupled plasma mass spectrometry. These analyses allow comparison of...

The Shalipayco Zn–Pb deposit, in central Peru, is composed of several stratabound orebodies, the largest of which are the Resurgidora and Intermedios, contained in carbonate rocks of the Upper Triassic Chambará Formation, Pucará group. Petrography suggests that a single ore-forming episode formed sphalerite and galena within vugs, open spaces, and...
