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.

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...

Intermountain West Transect

The USGS Intermountain West project was launched with the goal of producing an new digital geologic map database and 3D geologic model of a transect from the Rio Grande rift to the Basin and Range, based on a synthesis of existing geologic maps with new targeted new mapping, subsurface data, and other data sets. This database will integrate disparate map data, resolve inconsistent...

Cenozoic Landscape Evolution of the Southern Rocky Mountains

The Cenozoic Landscape Evolution of the Southern Rocky Mountains Project is a multi-year investigation funded by the National Cooperative Geologic Mapping Program. This project utilizes a combination of geologic mapping, geophysical surveys, basin modeling, and structural, neotectonic, geomorphic, volcanic, stratigraphic, and geochronologic studies to...

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...

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...

Denver Radiogenic Isotope Lab

Radiogenic isotopes are daughter nuclides derived from natural decay of radioactive parent nuclides. They are useful for determining radiometric ages of rocks, minerals, and soils, and can be used as natural tracers of lithologic, hydrologic, and biologic materials.  GEC scientists are currently focused on radiometric dating by U-Pb, U-Th, Sm-Nd, and Rb-Sr, as well as tracer studies using...

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.
