Late quaternary Alaskan paleoclimate : geoarchaeological insights into the Pleistocene-Holocene transition.
(2018-11-26)
Eastern Beringia is a region which has undergone dramatic changes since the end of the Last Glacial Maximum, environmentally and climatically. These changing conditions likely contributed to the changes in human behavior ...
Modeling the crust and upper mantle structure of the southern U.S. continental margin using seismic and gravity data.
(2019-11-07)
The southern U.S. continental margin is economically and scientifically significant as its crustal structure is home to abundant hydrocarbon reserves and records a rich geologic history. The latter spans ~1.35 Ga and ...
Salinity in the northern segment of the Brazos River Alluvium Aquifer : a hydro-forensic approach.
(2019-05-10)
The Brazos River Alluvium Aquifer is a minor aquifer in central and east Texas under water table conditions. It is an underutilized resource and may be considered a supplemental water source. However, variability in ...
Applied forensic investigation of elevated arsenic levels in the Central Texas Trinity Aquifer system.
(2015-07-22)
A recent change in EPA regulation lowered the maximum contaminate limit (MCL) of arsenic in drinking water from 50 to 10 μg/l. Lowering the MCL has put numerous water systems in Texas over the limit. An arsenic “hot spot” ...
Numerical simulation of a single fracture with various parameters.
(2017-06-15)
Hydraulic fracturing is the process of enhancing host rock permeability through injection of pressurized fluid in order to obtain oil and natural gas. Typically, microseismicity is used during the fracturing process to ...
Rhyolite lava emplacement dynamics inferred from surface morphology captured with drones.
(2019-07-12)
The fluid dynamic properties of lava control the formation of morphologic features during emplacement. Therefore, fluid dynamic properties of the lava during emplacement can be inferred by measuring morphologic features ...
The stratigraphic controls on development potential within the Lower Cretaceous glauconitic member sandstone, Jenner Field area, Southern Alberta, Canada.
(2017-08-02)
The Glauconitic Member of the Lower Cretaceous Upper Mannville Group consists of incised valley filling multi-story fluvial quartzose sandstone deposits that accumulated during a marine transgression. This study delineates ...
Seismic anisotropy in Texas and Oklahoma and its relationship to tectonic events that shaped southern Laurentia.
(, 2013-09-24)
We present new shear wave splitting measurements of approximately 1500 SKS
phases recorded at 176 broadband seismic stations deployed in Texas and Oklahoma.
SKS splitting on the North American (NA) craton show NE-SW fast ...
Age, genesis, and archaeological geology of the sandy mantle on the Gulf Coastal Plain of Texas.
(, 2013-05-15)
Alfisols exhibiting strong textural contrasts between sandy A-E horizons (sandy mantle) and clayey Bt horizons on the Gulf Coastal Plain have invoked debate among pedologists, geologists, and archaeologists about parent ...
Lithostratigraphic and depositional framework, near-surface Upper Pennsylvanian and Lower Permian strata, southern Brazos Valley, North-central Texas.
(1965)
The purpose of this study was to interpret the depositional framework of the original Cisco Group, Upper Pennsylvanian and Lower Permian, in the shallow subsurface of North-central Texas, Stratigraphic interpretation was ...
