Chemostratigraphy And Paleoenvironment Of The Smithwick Formation, Fort Worth Basin, San Saba County, Texas
(Geology, 2011-07-14)
The Early Pennsylvanian-Age Smithwick Formation was deposited in the tectonically active Fort Worth Basin in North Central Texas during a time of well-documented global climatic instability during the Late Paleozoic ice ...
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 ...
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, ...
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 ...
Constraining The Provenance Of Middle Cenozoic Fluvial Sandstone In The Central Rocky Mountains Using Detrital Zircon U-pb Geochronology And Sandstone Petrography
(Geology, 2014-09-17)
Detrital zircon U-Pb geochronology and sandstone petrography are studied to constrain the provenance of middle Cenozoic fluvial sandstone in the Central Rocky Mountains. Petrographic point counting of 12 sandstone samples ...
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 ...
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- ...
