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 ...
An Atlas Of Cenozoic Climate Zones
(Geology, 2012-07-25)
This atlas illustrates global climatic zones in five major turning points of Cenozoic climate history: the K/T, the Paleocene/Eocene Thermal Maximum (PETM), the Eocene/Oligocene Transition (EOT), the Late Miocene (Messinian), ...
Numerical Simulation Of The Base-level Buffers And Buttresses Conceptual Model Of Fluvial Systems
(Geology, 2012-07-25)
A Buffer in fluvial stratigraphy is a potentiometric surface which defines either: a) the lowest possible depth to which streams will incise; or b) the maximum elevation to which aggradation will occur; together, these ...
A Late Holocene Meander-braid Transition Of The Lower Missouri River Valley
(Geology, 2012-07-25)
Historically, the Lower Missouri River is known for being a temperate river that constantly and quickly reworks its floodplain with a braided network of channels; however, the river only recently became braided. Ox-bow ...
Chemostratigraphy Of The Eagle Ford Formation
(Geology, 2012-04-11)
The Late Cretaceous Eagle Ford Formation contains the Cenomanian-Turonian Boundary (CTB). It crops out along the Red River and extends southward through the Dallas-Fort Worth Area of Texas, Waco, Austin and west towards ...
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 ...
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 ...
