An Investigation Of Ams In Oman Ophiolite Gabbros, Sarah D. Trutner
Honors Papers
Crustal accretion processes at mid-ocean ridges are still poorly understood, and several competing models exist that try to explain exactly how magma from the mantle is incorporated into oceanic crust at a crustal spreading center. Ophiolites, or fragments of oceanic crust exposed on land, are useful sites at which to conduct rock fabric studies to understand oceanic crust formation processes. This study focuses on samples of upper foliated gabbros taken from the Oman ophiolite in order to characterize their fabric orientations and contribute to a better model of crustal formation. Much of the focus of this study is on using …
Paleoenvironmental Analysis Of Cretaceous Mudstones At Slope Mountain, Alaska Using Carbon Stable Isotopes, Ashley Ratigan
Paleoenvironmental Analysis Of Cretaceous Mudstones At Slope Mountain, Alaska Using Carbon Stable Isotopes, Ashley Ratigan
Honors Papers
This project uses field samples, microfacies analysis, and carbon stable isotopes of mudstones to determine past environmental conditions of North Slope, Alaska during the Albian-Cenomanian (Cretaceous). Samples were taken at Slope Mountain, Alaska located north of the Brooks Range. Slope Mountain includes the Torok Formation and the upper and lower Nanushuk Formations that consist of alluvial, deltaic, and shallow marine facies that were deposited into the North Slope foreland basin on the Arctic Alaska micro plate. An exhaustive search for identifiable microfossils, such as pollen, diatoms, and foraminifera in the samples yielded nothing but charcoal and carbon residue. No other …
