Verrucomicrobia: A Model Phylum To Study The Effects Of Deforestation On Microbial Diversity In Amazon Forest
(Environmental & Earth Science, 2011-03-03)
The Amazon rainforest is known for having a very high diversity of plants and animals. However, it is one of the least understood ecosystems regarding microbial diversity. Microorganisms are important for the ecological ...
An Updated GPS Velocity Field For Puerto Rico And Virgin Islands: Constraints On Tectonic Setting And Internal Deformation
(Geology, 2012-07-25)
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 ...
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 ...
Chemostratigraphy And Paleoceanography Of The Mississippian Barnett Formation, Southern Fort Worth Basin, Texas, USA
(Geology, 2011-10-11)
The Mississippian (Visean-Serpukhovian) Barnett Formation is a lithologic unit composed primarily of laminated siliceous mudstone and calcareous siliceous mudstone with significant phosphate and sulfide phases present. The ...
Bismuth-based Oxide Semiconductors: Mild Synthesis And Practical Applications
(Environmental & Earth Science, 2012-04-11)
In this dissertation study, bismuth based oxide semiconductors were prepared using 'mild' synthesis techniques - electrodepostion and solution combustion synthesis. Potential environmental remediation and solar energy ...
Integrated Chemostratigraphy And Paleoceanography Of The Mississippian Barnett Formation
(Geology, 2013-03-20)
The Barnett Formation was deposited on a gently sloping marine margin that ultimately became the Fort Worth Basin (FWB), a foreland basin that evolved during the late Paleozoic Era. The FWB formed as a result of the early ...
High Resolution Geochemistry Of The Cretaceous Eagle Ford Shale, Bee County, Texas
(Geology, 2013-03-20)
The Eagle Ford Formation of Bee County, Texas is a sporadically laminated carbonaceous dark mudrock. The depositional area of the Eagle Ford Formation stretches across the state of Texas in a northeast-southwest trend. ...
Morphology, Mechanisms, And Processes For The Formation Of A Non-bifurcating Fluvial-deltaic Channel Prograding Into Grapevine Reservoir, Texas
(Environmental & Earth Science, 2013-07-22)
Non-bifurcating channels in modern reservoirs, tie channels, and the Mississippi River Bird-Foot Delta share a common morphology that is likely due to an underlying common mechanism. Data analysis indicates that the Denton ...
Seismic Inversion In Fluvial Reservoirs: Building A Geologic Model-based Inversion For The Stratton Field 3D Survey
(Geology, 2010-03-03)
Seismic surveys, in particular 3-D surveys, are an important tool for imaging geologic structure in the subsurface; they are routinely applied to map structural trends and geometry to define the reservoir structure. Many ...
Chemostratigraphy, Paleoceanography, And Sequence Stratigraphy Of The Pennsylvanian-permian Section In The Midland Basin Of West Texas With Focus On The Wolfcamp Formation
(Geology, 2012-07-25)
The late Pennsylvanian to early Permian rocks (Wolfcampian and Leonardian) of the Midland Basin represent a single lithologic unit composed primarily of calcareous mudrocks, siliceous mudrocks, muddy carbonate-clast ...
