Framework Geology
Framework Geology
GECSC scientists create geologic maps and three-dimensional framework models of the rocks and surficial deposits at and beneath the Earth’s surface to provide information on critical ground-water aquifers, hazards (seismic, subsidence, landslide), resources (minerals, energy), and geomorphic system responses to environmental change.

USGS Geochron: A database of USGS geochronological and thermochronological data
The U.S. Geological Survey (USGS) has developed an updated geochronology database (USGS Geochron) to include geochronology summary and analytical data created or funded by the USGS.
National Geologic Synthesis
Surface (2D) and subsurface (3D) geologic data are critical for resource management, infrastructure design, hazards characterization, and basic earth science research. To meet these needs in a digital landscape, geologic maps must transition from static publications to machine-readable and discoverable digital databases that enable spatial analyses and queries (Shelton and others, 2022). In 2019...
Denali National Park Geohazards Geologic Mapping
Denali National Park (DENA) is a major draw for tourism and recreation and a major economic engine for central Alaska. However, the geologic forces that created the steep landscape of DENA also make it prone to geologic hazards (geohazards) like landslides, debris flows, and earthquakes. DENA has only one major road, called the ‘Park Road’, that serves nearly all of its infrastructure. Since 2017...
Ozark Dome-Arkoma Basin-Ouachita Transect
The Ozark Dome-Arkoma Basin-Ouachita Transect (ODABOuT) project examines the three-dimensional geology of a transect of the southern orogenic margin of North America in its best surface exposure in western Arkansas. The Ozark Dome and Arkoma Basin represent a foreland uplift and foreland basin that formed as a result of the impinging Ouachita orogenic belt. Understanding the geometry and evolution...
Geologic Framework of the Intermountain West
The Geologic Framework of the Intermountain West (IMW) Project conducts 1:24,000- to 1:100,000-scale geologic mapping to support framework geologic investigations. The IMW project is prioritizing development of a seamless, integrated geologic map database in targeted areas of the Intermountain West region of the United States that host substantial mineral, energy, water, and industrial material...
Geologic Mapping Studies at Buffalo National River, Northern Arkansas
Detailed geologic mapping is being conducted by the USGS in and adjacent to the Buffalo National River, a park administered by the National Park Service, to better understand and characterize the natural resources and associated ecosystems of this area within the Ozark Plateau region. General-purpose geologic maps are created to provide a framework for a host of natural resource, natural history...
Greater Platte River Basins and Northern Plains Geologic Framework Studies
Primary objectives of the project are to conduct surficial geologic mapping studies in the central and northern Great Plains in support of ecosystem and climate change research. Major goals are to obtain a better understanding of (1) past climate information recorded in the geologic record, and (2) geomorphic or climatic thresholds that may have triggered major changes in the ecosystems in the...
U.S.-Mexico Border Geologic Framework
The primary objective of the U.S.-Mexico border project is to provide framework geology through geologic mapping activities to support border-wide science investigations including assessing and evaluating groundwater, energy and mineral, and ecological resources, and identifying and investigating natural hazards, including landslide, earthquake, wildfire, and flood hazards.
