(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 ... -
Chemostratigraphy And Paleoenvironmental Significance Of The Pennsylvanian Smithwick Formation, Northern Llano Uplift Region, Texas
(Geology, 2013-03-20)The Early Pennsylvanian (Bashkirian-Moscovian) Smithwick Formation of Central Texas has been previously described as a marine transgressive, fairly homogeneous and fine-grained dark shale sequence with varying local ... -
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 ... -
Chemostratigraphy Of The Austin Chalk And Upper Eagle Ford Shale
(Environmental & Earth Science, 2014-07-14)A single drill core from La Salle, TX was analyzed for its chemical composition and percent concentration of both major and trace elements in order to understand depositional environments and local tectonic activity of the ... -
