Genesis and Taphonomy of a Crinoid Lagerstatte in the Upper Pennsylvanian Barnsdall Formation of Northeastern Oklahoma
(2010-10-20)
A 50-cm mudstone interval within the Upper Pennsylvanian Barnsdall Formation, exposed near Copan, Washington County, northeastern Oklahoma, records prodeltaic distal shelf sedimentation in an oxygenated, low energy setting. ...
A Geochemical and Hydrological Assessment of Oil and Related Compounds from the 2010 Deepwater Horizon Oil Spill in Gulf Coastal Saltmarshes
(2013-08-02)
In April of 2010, the Macondo-1 wellhead ruptured in the Gulf of Mexico, releasing an estimated 4.9 million barrels of crude oil. Ten saltmarsh sites along the northern Gulf coast were investigated to determine the fate, ...
Geochemistry and Mineralogy of Eastern Ag-Rich Epithermal Veins in the Midas District, Nevada, USA
(2012-04-09)
Five Ag-rich epithermal veins were recently discovered in the eastern section of the Midas district in northern Nevada. Initial data collected indicated that these veins had a significantly higher quantity of silver relative ...
Geochronology and Geochemistry of Mid-Miocene Bonanza Low-Sulfidation Epithermal Ores of the Northern Great Basin, USA
(2008-05-15)
New high precision 40Ar/39Ar geochronology
conducted on previously undated deposits (or deposits with older, less precise K/Ar dates only), indicates that low-sulfidation epithermal Au-Ag mineralization in the northern ...
Geochronology and structural geology of the Kjerringøy Peninsula, Nordland, Norway
(2014-10-30)
Field mapping, structural and petrographic analysis, ID-TIMS U-Pb geochronology, 40Ar/39Ar thermochronology, and chemical dating of minerals were employed to decipher the geologic history of the Salten area of north-central ...
A Geographical Investigation of Football and its Fans at Auburn University
(2012-01-09)
In Auburn, AL, football, and especially college football, reigns supreme. Particularly, interest is placed on the Tigers, the team representing the local institution, Auburn University. This research paper investigates ...
Geology of the 1:24,000 Roanoke East Quadrangle and investigations of the Long Island Creek Gneiss within the southernmost Appalachians, Alabama and Georgia
(2017-07-22)
The geology of the 1:24,000 Roanoke East, Alabama, Quadrangle has been determined to be of high mapping priority by the State Geologic Mapping Advisory Committee due to the rapid development along the I-85 corridor west ...
Geology of the 1:24,000 Tallassee, Alabama, Quadrangle, and its Implications for Southern Appalachian Tectonics
(2008-05-15)
The 1:24,000 scale Tallassee, Alabama, Quadrangle, was mapped to characterize lithologies and structures in the southernmost exposures of the southern Appalachians. Four deformation events are recognized. D1 was associated ...
