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.

In situ lung dust analysis by automated Field Emission Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy: A method for assessing inorganic particles in tissue from coal miners
Context.—Overexposure to respirable coal mine dust can cause severe lung disease including progressive massive fibrosis (PMF). Field emission scanning electron microscopy with energy dispersive x-ray spectroscopy (FESEM-EDS) has been used for in situ lung dust particle analysis for evaluation of disease etiology. Automating such work can reduce time, costs, and user bias.Objective.—To develop and
Earthquake relocations delineate discrete a fault network and deformation corridor throughout Southeast Alaska and Southwest Yukon
Deformation in southeastern Alaska and southwest Yukon is governed by the subduction and translation of the Pacific-Yakutat plates relative to the North American plate in the St. Elias region. Despite notable historical seismicity and major regional faults, studies of the region between the Fairweather and Denali faults are complicated by glacial coverage and the remote setting. In the last decade

Persistent Science Challenges in Legacy Mine Land Site Management
The objective of this project is to provide targeted research results to benefit cooperators managing legacy mine land sites in the western U.S. by addressing three persistent scientific challenges: (1) determining the contribution of mining-related metal sources to water quality degradation when substantial natural background metal sources are also present; (2) adequately characterizing key...
Porphyry Copper Systems of the Boulder batholith, Montana
The project seeks to better understand the mineral systems of the Boulder batholith and surrounding region in Montana using new airborne geophysical data in conjunction with geologic mapping.
USMIN Mineral Deposit Database
Our objective is to develop a national-scale, geospatial database that is the authoritative source of the most important mines, mineral deposits, and mineral districts of the United States.
