Factor influencing headcut migration within a cohesive Texas Black-Land gully.
(2017-12-01)
Gully erosion degrades the Black-Land Prairies (BLP) (Texas), affecting agricultural productivity. It is initiated by rill and inter-rill erosive processes and exacerbated by storm frequency and duration. Few studies have ...
Geology of the Late Pleistocene artifact-bearing Wasiriya Beds at the Nyamita locality, Rusinga Island, Kenya.
(, 2011-12-19)
This study investigated the sedimentology and stratigraphy of the Late Pleistocene Wasiriya Beds at the Nyamita locality on Rusinga Island, Kenya in northeastern Lake Victoria. Little is yet known about this region during ...
Seismic tomographic imaging reveals possible lithospheric erosion beneath Trans-Pecos Texas and Southeastern New Mexico.
(, 2011-12-19)
Results from the 1999-2001 La Ristra array revealed a fast seismic velocity anomaly beneath the Rio Grande rift, attributed to a lithospheric “drip” into the mantle, perhaps due to edge-driven convection. To investigate ...
The sequence stratigraphic evolution of the Sturgeon Lake bank, central Alberta, Canada and its regional implications.
(2006-05-29)
Sturgeon Lake South (SLS) is an isolated Devonian (Late Frasnian) platform located within the Western Canada Sedimentary Basin (WCSB). Stratigraphic correlation of the Leduc Formation across the WCSB reveals a dominantly ...
Organic matter structural changes during catagenesis : implications of kerogen chemical structure on petroleum yield and composition.
(2018-04-16)
This work describes the machining of cost-efficient hydrous pyrolysis reactors and furnaces used to simulate natural oil forming (catagenesis) processes. These reactors were used to generate petroleum products from both ...
The quantification and characterization of soil carbon pools in biofuel agriculture.
(2019-04-18)
The shift toward renewable energy resources through agricultural biofuel production provides an opportunity to study and implement sustainable land management practices that improve soil health and a deeper understanding ...
Analysis of calcite-filled faults in carbonate strata, balcones trend near Waco, Texas.
(, 2011-09-14)
Five normal faults exposed in the Lehigh Quarry near Waco, Texas, were analyzed. The mechanical stratigraphy of the quarry ranges from relatively strong chalk to marly chalk to chalky marl to relatively weak marl. Higher ...
Charcoal chemistry : developing a proxy for paleofire regimes.
(, 2013-09-16)
Wildfires have occurred over geologic time since the evolution of land plants and affect global biogeochemical cycling and ecosystem processes. Charcoal particles in the geological record may contain information on several ...
Methods of determining stream setback corridors in urban watersheds from remotely sensed data in the Dallas metropolitan area, Texas.
(2010-02-02)
Bank stability in urbanized streams is worsening in response to increased runoff, causing unprecedented stream erosion. Eroding banks pose a serious threat to existing structures prompting cities to create buffer zone ...
Petrophysical facies mapping of the Pennsylvanian Cline Shale, Midland Basin, West Texas.
(2015-07-31)
The Cline Shale is a Pennsylvanian unconventional shale resource play located in the Midland Basin, west Texas. This study evaluates the depositional, stratigraphic and petrologic controls on Cline Shale reservoir quality ...
