(Environmental & Earth Science, 2008-08-08)Groundwater sampled were collected from well sites located within the Carrizo Sand aquifer in Atascosa and McMullen counties in Texas, and also within the Aquia Aquifer, Maryland in the counties of Queen Anne's, Kent, and ... -
Geochemistry Of Molybdenum In The Aquia Aquifer, Maryland, USA
(Geology, 2010-03-03)The present study contributes to the understanding of controls on and behavior of molybdenum (Mo) in an aquifer, and its potential as an indicator of changing redox conditions along the groundwater flowpath. The central ... -
Geochemistry Of The Haynesville Formation Using The Carthage Core In Panola County, Texas
(Geology, 2014-07-14)The Haynesville Formation has been described as a fine grained, organic, homogeneous shale that was deposited during the warm upper Jurassic (Kimmeridgian) in the tectonically formed East Texas Basin (Mainali, 2011). The ... -
A Geologic Map And Stratigraphy Of Upper Guadalupian - Lower Ochoan (permian) Strata Along And East Of Fm 2185 In The Northwestern Apache Mountains Near Van Horn, West Texas
(Geology, 2010-03-03)A surface geologic map is constructed for an area of approximately four square miles east of Texas FM 2185, 35 miles northeast of Van Horn, West Texas in the northwestern part of the Apache Mountains. Middle Permian ... -
Geology Of The Northwestern Apache Mountains, Southeast Culberson County, West Texas, U.S.A.
(Environmental & Earth Science, 2009-09-16)Middle Permian marine (Bell Canyon Formation) strata along the southwestern margin of the Delaware Basin in southeastern Culberson County, Texas provide excellent exposures of basinal and slope strata, useful fossils for ... -
Geomechanical Analysis of Rock Brittleness with Comparisons to the Mineralogical Brittleness Index
(2016-05)A significant area of research within the Oil and Gas industry centers around the understanding of rock brittleness and fracture mechanics related to inducing and extending hydraulic fractures. This study defines rock ... -
A Geomechanical Equation For Fracture Density/brittleness And Comparisons With A Mineralogical Brittleness Index
As production of hydrocarbons from tight reservoirs becomes more prevalent, the need to understand fracture density and what can affect fracture density has become the goal of new research. In this study, fracture density ... -
GEOSPATIAL ANALYSIS OF POTENTIAL FLOODING FROM STORM SURGE AND SEA-LEVEL CHANGE ON THE TEXAS COAST BY 2100
(2020-05-14)Tropical cyclones pose a major hazard to the State of Texas. Anthropogenic climate change and global warming have the potential to increase extreme weather events and lead to enhanced flood hazard zones. This study aims ... -
GLOBAL MARINE CARBON EXPORT PRODUCTION DURING EOCENE HYPERTHERMAL EVENTS
(2017-12-20)Early Eocene hyperthermal events can be an analog for global warming. Pelagic marine barite in deep sea sediment is a proxy for marine export production of organic matter into the deep ocean. Pelagic marine barite accumulation ... -
Growth And Toxicity Of Prymnesium parvum In Long-term Cultures At Low Temperature And Salinity
(Environmental & Earth Science, 2011-07-14)There is a paradox reported concerning observations of toxic blooms of Prymnesium parvum in winter in Texas (USA), and its growth performance in the laboratlry. Culture experiments indicate relatively high optimum temperature ... -
Growth Rates Of The Harmful Alga Prymnesium parvum: An Attempt To Identify The Salinity Threshold For Algal Blooms
(Environmental & Earth Science, 2013-03-20)Harmful algal blooms due to Prymnesium parvum have occurred in Texas for nearly three decades in waters of moderate salinity. More recently, blooms have occurred in locations such as West Virginia, in waters of very low ... -
Heavy Metal Contamination Of Road Dust In Lanzhou, China
(Environmental & Earth Science, 2012-07-25)Road dusts were collected from the streets of the city of Lanzhou, the capital and largest city of Gansu Province in Northwest China. The potential health hazard posed by contaminated road dusts may be considerable for ... -
