Paleoecological Analysis Of The Clayton Formation (Paleocene) Near Malvern, Arkansas, Brenna J. Hart
Paleoecological Analysis Of The Clayton Formation (Paleocene) Near Malvern, Arkansas, Brenna J. Hart
Honors Theses
The Clayton Formation is a section of the Midway Group immediately above the Cretaceous-Paleogene boundary that contains marine fossils from the Paleocene Epoch. The formation is composed of glauconitic sand, clay, marl, and limestone. Fossils within the formation commonly occur in clay or are concentrated in conglomeratic lag lenses. To assess paleoecology of the region during the Paleocene, the Clayton Formation was sampled for fossil content at a distinctly visible exposure along Interstate 30 near Malvern, Arkansas, that was excavated as part of a landslide mitigation project. Complimentary sites were sampled nearby along the Ouachita River and behind a shopping …
A Study On Gaseous Ebullitions Of De Gray Reservoir, Arkansas, David Pinkston
A Study On Gaseous Ebullitions Of De Gray Reservoir, Arkansas, David Pinkston
Honors Theses
This study was undertaken in order to determine the nature of and the factors that influence the gaseous ebullitions of De Gray Reservoir near Arkadelphia, Arkansas during a yearly cycle.
Two major types of gaseous ebullition are described in the literature. The first has to do with the production and ebullition of elemental oxygen from photosynthesis (Porcella et al., 1975). Hutchinson (1957) predicts that the formation of oxygen bubbles in this manner is limited to very shallow, well lighted, warm waters.
The second type of gaseous ebullition involves the anaerobic digestion of organic matter (Reeburgh, 1969). Anaerobic conditions exist in …
The History Of The Stream Preservation Movement In Arkansas, Rex Moreland Terry
The History Of The Stream Preservation Movement In Arkansas, Rex Moreland Terry
Honors Theses
The history of Arkansas' Stream Preservation movement is not a long one, because only in the recent past have Arkansans taken a serious look at the long term effects of such things as damming streams and clearing land.
The core of the movement for stream preservation centers around the Buffalo River, in the Northwest Arkansas Ozarks. Because of this, the bulk of this paper will be devoted to the Buffalo.
