3D Geologic Modeling

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...

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...

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...

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...

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.
