Predicting The Ancient Occurrence Of Evaporites Using Paleoclimate Modelling
(Geology, 2012-04-11)
Evaporites are climatic indicators that depend on two main variables: mean annual temperature and mean annual precipitation. This study constructs a model that predicts the localities of ancient evaporites based on paleo- ...
Climate Reconstruction Using Trace Element And Stable Isotope Signatures Preserved In An Early Late Pleistocene Stalagmite From Buckeye Creek Cave, Appalachian Mountains, Southern West Virginia, Usa
(Geology, 2012-04-11)
An early-Late Pleistocene stalagmite was recovered from Buckeye Creek Cave (37°58.57'N, 80°23.98'W), southeastern West Virginia, USA. The growth axis of stalagmite BCC-025 was sampled for δ18O, δ13C, and Sr/Ca of the ...
Chemostratigraphy And The Paleoceanography Of The Bossier-Haynesville Formation, East Texas Basin, Texas and LA, USA
(Geology, 2012-04-11)
The fine-grained, dark, organic, calcareous Haynesville shale (Kimmeridgian), and the overlying carbonate-poor Bossier shale (Tithonian) was deposited during the warmer Jurassic period in the tectonically formed East Texas ...
The Impact Of Buffer Zone Changes on the Architecture Of The Paleozic Lower Cutler Beds Of Utah
(Environmental & Earth Science, 2012-04-11)
The Shafer basin fluvial units, as being part of the Paradox fold and fault belt basin, received sediments from alluvial fans through mixed braided-meandering river systems that eroded the clastic rocks of the Uncompahgre ...
Chemostratigraphy Of The Upper Cretaceous From Central And South Texas With Focus On The Eagle Ford Group
(Geology, 2013-10-22)
The fine-grained organic-rich rocks of the Eagle Ford (Cenomanian-Turonian) were deposited during the Upper Cretaceous in the shallow waters of the Western Interior Seaway. Five drill cores recovered from two counties, ...
Predicting Fracture Density In The Eagle Ford (Boquillas) Formation, Val Verde Basin, Texas
(Environmental & Earth Science, 2014-03-12)
Fracture density in hydrocarbon reservoirs is an important variable for efficient production of oil and gas in tight reservoirs. Fracture density is the fracture surface area per unit of volume, and the higher the reservoir ...
A Model Of Short Term Surface Deformation Of Soufriere Hills Volcano, Montserrat Constrained By GPS Geodesy
(Geology, 2013-10-22)
Geodetic surveying is a core volcano monitoring technique. Measurements of how the crust deforms can give valuable insight into the mechanisms and processes that drive an eruption, and the way in which they change (Odbert ...
Chemostratigraphy Of The Mississippian-age Barnett Formation, Fort Worth Basin, Wise County, Texas USA
(Environmental & Earth Science, 2013-07-22)
The Mississippian- age Barnett Formation is a shale-gas system dominated by fine grained clay- to silt -size particles deposited in the Fort Worth Basin, a peripheral foreland basin that formed during the late Paleozoic ...
Reducing Pb Bioaccessibility In Soil Through The Addition Of Apatite II
(Environmental & Earth Science, 2014-03-12)
This study was an investigation of the bioaccessibility of Pb in the presence of phosphate acting as an immobilizing constituent in the form of fish bone material, specifically Apatite II. Phosphate-induced Pb immobilization ...
Hydrogeochemical Evolution Of Arsenic Along Groundwater Flow Paths: Linking Aqueous And Solid Phase Arsenic Speciation
(Environmental & Earth Science, 2007-08-23)
The central hypothesis of this Doctoral research work is that changes occurring along groundwater flow paths that accompany chemical weathering and oxidation-reduction reactions catalyze both arsenic (As) mobilization from, ...
