Tectonic processes and continental hydroclimate during the Laramide deformation in the central Rocky Mountains
(2017-05-12)The central Rocky Mountains in western U.S.A. is a geologic province formed by the low-angle subduction of the Farallon oceanic plate under the North American continental plate during the latest Cretaceous–early Eocene ... -
A Tectonic Reconstruction Of Accreted Terranes Along The Paleo-Pacific Margin Of Gondwana
(Environmental & Earth Science, 2014-07-14)The southern oceanic margin of Gondwana was nearly 40,000 km long or 24,854.8 miles. The southern margin was the result of the Terra Australis orogen. Spanning 18,000 km or 11,184.7 miles and is proposed as one of the ... -
The Characterization of Friable Surface Deposits Across North Africa Utilizing Computer Controlled Scanning Electron Microscopy (CCSEM)
(2016-05-10)Analysis of the mineral constituents of friable surface deposits from the Burkina Faso and Niger regions, North Africa, was undertaken by computer controlled scanning electron microscopy (CCSEM) to try and identify ... -

(2021-05-09)The microfossil association of the Salesville Formation (Strawn Group, Missourian, Pennsylvanian) of small foraminifers, fusulinids, conodonts, ostracodes, holothurian sclerites, and rare radiolarians, has received very ... -
The Negative Impacts of Lead- Contaminated Superfund Sites and the Toxicological Effects on Children in Dallas County
(2018-06-11)This Study was conducted to investigate the toxicological effects of lead on children, from the age of 0 years old to 18 years old, that reside or attend schools, located within the 5-mile radius, of lead contaminated ... -
THE NORTH CENTRAL TEXAS URBAN HEAT ISLAND MAGNITUDE AND ITS RELATION TO SEVERE AND EXTREME DROUGHT
(2021-05-04)This study focuses on how summer droughts affect the urban heat island (UHI) in Dallas-Fort Worth (DFW). The nocturnal UHI has been computed by comparing downtown temperature observations to rural temperature measurements ... -
The Variance Of Methane Adsorption And Its Relation To Thermal Maturity In The Marcellus Shale
(Geology, 2015)In unconventional shale gas plays, gas-in-place is a major factor in evaluating the shale’s potential and determining well density and lateral placement. The two main contributors to total gas-in-place are free gas and ... -
Thermal Maturity And Porosity Development During Catagensis In The Barnett Shale, Fort Worth Basin, Texas
(Geology, 2012-04-11)Unconventional resource plays are typified by significantly recoverable volumes of thermally mature hydrocarbons (oil, condensate and/or gases) trapped within a low permeability shale formation acting as source, reservoir ... -
Timing, Provenance, And Paleoclimate Implications Of The Cenozoic Eolian Deposition In The Central Rocky Mountains, USA
(Geology, 2014-03-12)This study applies detrital zircon U-Pb geochronology and sandstone petrography to constrain the timing and provenance of Cenozoic eolian sandstone in the central Rocky Mountains. Four samples, collected at the transition ... -
Trace Element Geochemistry In Groundwater Flow Systems
(Environmental & Earth Science, 2011-03-03)This research focuses on trace element geochemistry in three groundwater flow systems: the Carrizo Sand, the Upper Floridan, and the Aquia aquifers. The focus is threefold: (i) studying the geochemical behavior, concentrations, ... -
TRACING PALEOZOIC SILICICLASTIC SEDIMENT DISPERSAL TO THE FORT WORTH AND MIDLAND BASINS: IMPLICATIONS FOR PALEOGEOGRAPHY AND ORGANIC MATTER ACCUMULATION
(2019-05-14)The Fort Worth and Midland Basins in central and West Texas are major petroleum-producing systems in North America. The provenances of the thick Paleozoic sedimentary rocks in both basins are poorly constrained, although ... -
Trends In Seasonal Climate Variance In The Subtropical Reservoir Joe Pool Lake, Texas: Implications Dissolved Oxygen And Nutrient Distribution
The primary causes of seasonal variance in temperature, hydrological cycle, and nutrient distribution of lakes, and the processes explaining these changes including climate change and land use changes have been investigated ... -
TWO CRETACEOUS TALES OF THE LAND AND THE SEA
(2019-05-07)The Cretaceous Period (145-66 Ma), with no magnetic reversal for ~79 Ma, is generally termed as the Cretaceous Normal Superchron or the Magnetic Quiet Zone. There is evidence of at least two major large scale, global ... -
An updated GPS velocity field for Puerto Rico and the Virgin Islands: Constraints on tectonic setting and internal-deformation
(2014-09-17)Puerto Rico and the northern Virgin Islands define the eastern end of the Greater Antilles, while the Puerto Rico trench and the Muertos Trough define the northern and the southern limits of the North American - Caribbean ... -
