Structural Geology of the Caddo Gap Area, Ouachita Mountains, Arkansas
… of the Benton Uplift, the orogenic core of the Ouachita Mountains. Recent field mapping focused on delineating stratigraphic and structural relationships in the southern part of the quadrangle to improve existing reconnaissance-scale maps of the area. New structures were discovered that provide …

Reproductive Patterns of Three Plethodon Salamanders Endemic to the Ouachita Mountains
… the Caddo Mountain salamander, Plethodon ouachitate, the Rich Mountain salamander and Plethodon fourchensis, the Fourche Mountain salamander were made in 1985 and 1986. Reproductive patterns, fecundity and length-weight relationships were examined. When compared to male SVL, female P. …

Field-based Constraints on the Origin of the Benton Uplift, Ouachita Mountains
<p>The Ouachita Mountains are an east-west trending fold-and-thrust belt exposed in west central Arkansas and southeastern Oklahoma. The Mississippian-Pennsylvanian Ouachita orogeny occurred when the Sabine arc terrane collided during south-facing subduction, during closure of the Cambrian passive …

Population Dynamics of Ouachita Dusky Salamanders (Desmognathus brimleyorum) in a Managed Forest Landscape
… on a stream-dwelling salamander endemic to the Ouachita Mountains, Desmognathus brimleyorum. We specifically focused on two possible mechanisms of salamander abundance shifts, survival and movement. We conducted a capture-mark-recapture (CMR) study at three streams within intensely managed pine …

The use of right of ways by primary burrowing crayfishes in the Ouachita Mountains Ecoregion of Arkansas
… habitat models for these two species in the Ouachita Mountains Ecoregion (OME) of western Arkansas in the spring of 2014 and 2015. My first objective was to determine the fine-scale habitat preferences of F. harpi and P. reimeri in relation to their occurrence in roadside ditches. My analysis …

Structural Geology of The Brady Mountain Area, Ouachita Mountains, Arkansas: Integrating Field Mapping, Geospatial Techniques, Photogrammetry And 3D Modeling For Structural Analysis
<p>Much of the Ouachita orogenic belt, representing the deformed Paleozoic rocks flanking the southern margin of the North American craton, is buried beneath post-orogenic Mesozoic and Tertiary sediments composing the Gulf Coastal Plain. The Ouachita Mountains of Arkansas and Oklahoma are the …

Seismic Velocity and Radial Anisotropy in the Crust and Upper Mantle of the South Central United States from Surface Wave Tomography
… appears in the coastal plain to the south of the Ouachita front due to thick sediments. In the middle and lower crust, the Ouachita Belt in Texas is characterized by a seaward-dipping high-velocity band, which is not observed in the east Ouachita, indicating structural variation along the orogeny. …

Comparative Geochemical Analysis of Ordovician and Mississippian Cherts in Relation to the Northern Arkansas and the Tri-State Mississippi Valley-type Ore Districts
… and clastic formations found within the Ouachita Basin of west-central Arkansas and northward onto the Ozark Dome have experienced interaction with hydrothermal fluids due to tectonic forces produced by the Ouachita Orogeny. Lead (Pb) isotope analyses and resulting values produced through …

Early and Middle Atokan Lithostratigraphy and Reservoir Development, Northern Arkoma Basin, Northwestern Arkansas
… foreland arc basin associated with the Ouachita orogenic belt. In Arkansas, the basin is bounded by the Ouachita belt to the south and the Ozark Dome to the north. Sedimentary rocks of early to middle Atokan age are present in the shallow subsurface at the northern margin of the Arkoma …

Structural geometry of the frontal Ouachitas-Arkoma basin transition zone in Western Arkansas
… Creek Fault are the leading-edge thrusts of the Ouachita fold-thrust belt and form the southern boundary of the Arkoma foreland basin in Oklahoma and Arkansas, respectively. Strain partitioning between the fold-thrust belt and the foreland basin is accommodated by the Wilburton Triangle Zone in …

The sedimentology and stratigraphy of Salt Creek Field, Kent County, Texas
… Atoll is contemporaneous with peak Marathon-Ouachita orogenesis. A critical question for understanding the Horseshoe Atoll geologic framework is whether LPIA-associated glacioeustacy or Ouachita tectonics was the main driver for the development of the observed stratigraphic architecture and …

Structure and Stratigraphy of a Complex Anticlinal Feature, Backbone Anticline, Arkoma Basin, Arkansas
… Basin of Arkansas and Oklahoma formed in the Ouachita foreland during the late Mississippian and Pennsylvanian periods (about 290-to 330 million years ago). The basin developed in response to convergent tectonic boundaries that closed obliquely from west to east associated with Ouachita …
