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 ...
Morphology Of The Lower Missouri River: The Processes Involving Development Of Highly Sinuous Gooseneck Loop Cutoffs Exposed In The Surficial Deposits Of The River Floodplain
(Geology, 2012-04-11)
Mapping the surficial deposits of the Missouri River from Sioux City, Iowa to Mondamin, Iowa brought to light a prominent set of landforms exposed in the floodplain and which are also easily visible via aerial photography. ...

The Pennsylvanian and lowermost part of the Permian strata in North-Central Texas is assigned to the Strawn, Canyon, and Cisco Groups. The Canyon Group is approximately equivalent to the middle-upper part of the Missourian ...
Reducing Lead Bioavalability In Soil By Adding Apatite II
(Environmental & Earth Science, 2012-04-11)
This study was an examination of phosphate-induced immobilization of lead (Pb) in soils through addition of apatite II (fish bone material). The sources of Pb minerals in the soils examined in this in situ remediation study ...
