Ozark Dome-Arkoma Basin-Ouachita Transect Active
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 of this tectonic connection gives insight into many scientific and societal questions.
The ODABOuT project will document the geometry and evolution of the late Paleozoic southern continental margin from the accretionary fold/thrust belt through the foreland basin to the foreland uplift. The project will investigate the role of pre-existing basement structures on basin geometry, fluid flow, and the potential for induced seismicity as well as the bedrock controls on Quaternary landscape development. The proposed publications from this work will include geophysical maps and digital geologic maps at a 100,000-scale as well as regionally balanced cross-sections and structure contours on key stratigraphic horizons to represent three-dimensional framework.
The geologic mapping will summarize existing maps as well as new work based on field inspections and remotely sensed information from geophysical surveys and high-resolution topography available from recent Lidar surveys. Drill holes and seismic lines from energy development are available in the Arkoma Basin and southern Ozarks for subsurface control.
The geologic maps and three-dimensional geology framework models produced by this project will help understand the distribution of ground-water, mineral, and energy resources as well as the potential for natural hazards.
This work is being conducted in collaboration with a number of partners and interested parties including the Arkansas Geological Survey, the U.S. Forest Service, the National Park Service, Arkansas State Parks, and several academic institutions such as University of Arkansas and Arkansas Tech University.
