The origin of mid-ocean ridge basalts : insights from trace element contents in anorthite, anorthite-hosted melt inclusions, and ocean core complexes

Creator:: Weinsteiger, Allison B.
Abstract:: The primary goal of this study is to access the processes that alter primary melts after segregation from a mantle source and ultimately form petrologic Layers 2 and 3 of the Ocean Crust. Mineral, melt inclusion, and whole rock chemical compositions are utilized to further the understanding of 1) the...

The changing glaciers of Mt. Hood, Oregon and Mt. Rainier, Washington : implications for periglacial debris flows

Creator:: Ellinger, Jonathan R.
Abstract:: Mountain glaciers are receding worldwide with numerous consequences including changing hydrology and geomorphology. This study focuses on changes in glacier area on Mt. Hood, Oregon and Mt. Rainier, Washington where damaging debris flows have occurred in glaciated basins. Landsat imagery is used to map debris-free ice on a decadal time...

Multidecadal variability of atmospheric methane, 1000–1800 C.E.

Creator:: Mitchell, Logan E., Brook, Edward J., Sowers, Todd, McConnell, J. R., and Taylor, Kendrick
Abstract:: We present a new high-precision, high-resolution record of atmospheric methane from the West Antarctic Ice Sheet (WAIS) Divide ice core covering 1000–1800 C.E., a time period known as the late preindustrial Holocene (LPIH). The results are consistent with previous measurements from the Law Dome ice core, the only other high-resolution...

Late Pleistocene and Holocene glacier and climate change

Creator:: Marcott, Shaun Andrew
Abstract:: This dissertation presents results from three studies that address major scientific questions in glacial geology and paleoclimatology for the late Pleistocene and Holocene using relatively new geochemical and statistical techniques. Each of the studies attempts to answer a longstanding question in the respective field using geochemical or statistical methods that...

Genesis of the El Salvador porphyry copper deposit, Chile and distribution of epithermal alteration at Lassen Peak, California

Creator:: Lee, Robert G. (Robert George)
Abstract:: The El Salvador porphyry copper deposit in the Indio Muerto district of northern Chile has been geologically investigated for more than 60 years and provides one of the best bases for understanding similar environments of ore formation elsewhere in the world. Fourteen new zircon U/Pb isotopic ages obtained via in...

Cycles of life and landscape : interpreting the geological foundation of Shenandoah National Park

Creator:: Kelly, Wendy Sonya
Abstract:: The significance of geology is commonly overlooked by the general public and underrepresented in free-choice learning environments including national parks that exhibit spectacular examples of geological features and processes. Parks are a major contributor to public learning, and a key way to teach how geology influences many aspects of our...

Analysis of semi-volatile trace metals in basaltic glass by LA-ICP-MS

Creator:: Loewen, Matthew W.
Abstract:: Semi-volatile trace metals (e.g., Cd, Sn, Pb, Zn, Cu, Mo) have been analyzed by using laser ablation ICP-MS in a number of silicate glasses (GSE-1G, GSD-1G, NIST 610, NIST 612, BCR-2G, BHVO-2G). Our work investigates and highlights sources of uncertainty in the analysis of semi-volatile metals using LA-ICP-MS. We identify...

A preliminary assessment of hydrogeologic suitability for Aquifer Storage and Recovery (ASR) in Oregon

Creator:: Woody, Jen
Abstract:: An ASR metric and site rating index applied to over 120 municipal and agricultural locations across Oregon, combined with comparison to case study data from existing ASR sites, indicate that more than 50% of selected sites are hydrogeologically suitable for ASR. The ASR metric is a ratio of aquifer storage...
