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 six scientific branches:
Isotope and Aqueous Geochemistry
Economic and Framework Geology

New USGS Map Helps Identify Where pyrrhotite, a Mineral that Can Cause Concrete Foundations to Fail, May Occur
The USGS has released its first-ever map of where the mineral pyrrhotite may occur in the contiguous United States. This research was mandated by Congress in the FY2019 appropriations bill for the USGS and was supported by the USGS Mineral Resources Program.

Systems-deposits-commodities-critical minerals table for the earth mapping resources initiative
To define and prioritize focus areas across the United States with resource potential for 35 critical minerals in a few years’ time, the U.S Geological Survey Earth Mapping Resources Initiative (Earth MRI) required an efficient approach to streamline workflow. A mineral systems approach based on current understanding of how ore deposits that...

Bayesian modeling of non-stationary, univariate, spatial data for the Earth sciences
Some Earth science data, such as geochemical measurements of element concentrations, are non-stationary—the mean and the standard deviation vary spatially. It is important to estimate the spatial variations in both statistics because such information is indicative of geological and other Earth processes. To this end, an estimation method is...

User guide to the bayesian modeling of non-stationary, univariate, spatial data using R language package BMNUS
Bayesian modeling of non-stationary, univariate, spatial data is performed using the R-language package BMNUS. A unique advantage of this package is that it can map the mean, standard deviation, quantiles, and probability of exceeding a specified value. The package includes several R-language classes that prepare the data for the modeling, help...
