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)

Quantifying model structural uncertainty using airborne electromagnetic data
The ability to quantify structural uncertainty in geological models that incorporate geophysical data is affected by two primary sources of uncertainty: geophysical parameter uncertainty and uncertainty in the relationship between geophysical parameters and geological properties of interest. Here, we introduce an open-source, trans-dimensional...

Alkalic-type epithermal gold deposit model; Chapter R in Mineral deposit models for resource assessment
This report summarizes the primary characteristics of alkalic-type epithermal gold (Au) deposits and provides an updated descriptive model. These deposits, primarily of Mesozoic to Neogene age, are among the largest epithermal gold deposits in the world. Considered a subset of low-sulfidation epithermal deposits, they are spatially and genetically...
Kelley, Karen D.; Spry, Paul G.; McLemore, Virginia T.; Fey, David L.; Anderson, Eric D. Hydrogeochemistry in the Yukon-Tanana Upland region of east-central Alaska: Possible exploration tool for porphyry-style deposits
A hydrogeochemical study using high resolution ICP-MS was undertaken at the Taurus and other porphyry Cu-Mo(-Au) occurrences and Ag-Au-Cu (+/- Pb, Zn) occurrences with epithermal-style characteristics in the Yukon-Tanana upland region of eastern Alaska. Surface water samples were collected from 30 sites on creeks that drain known deposits and...
