The provenance and trace element signatures of MORB anorthitic plagioclase

Creator:: Burleigh, Andrew W.
Abstract:: In an attempt to understand the phase equilibria and petrogenesis of MORB anorthitic plagioclase, Cr-spinel commonly hosted within anorthitic plagioclase has been investigated petrographically and compositionally. Based on spinel-anorthite relationships from three samples of plagioclase ultra-phyric basalt (PUB; Southeast Indian Ridge, Axial Seamount and West Valley Segment, Juan de Fuca...

Geologic structure and exhumation accompanying Yakutat terrane collision, southern Alaska

Creator:: Johnston, Sarah A.
Abstract:: The climatic and tectonic framework of the St. Elias orogen makes it an excellent place to study the interactions between tectonic processes such as deformation and erosive processes, in particular glacial erosion. One type of link between these processes, proposed by numerical models of orogenic development, is an effect of...

Helium isotope variations in peridotite, gabbro and basalt from the Kane Oceanic Core Complex

Creator:: Konrad, Kevin
Abstract:: The Kane Oceanic Core Complex (OCC) is a valuable window into crustal architecture and chemical composition of the lithosphere beneath a slow-spreading ocean ridge. A suite of > 30 samples (comprised of whole rocks, mineral separates and basalt glasses) has been analyzed for ³He/⁴He isotope ratios and He concentrations. Gas...

Timescales of large silicic magma systems : investigating the magmatic history of ignimbrite eruptions in the Altiplano-Puna Volcanic Complex of the Central Andes through U-Pb zircon dating

Creator:: Kern, Jamie M.
Abstract:: The Altiplano-Puna Volcanic Complex in the Central Andes is one of the youngest large silicic volcanic fields (LSVFs) in the world, erupting over 13,000 km³ of material during multiple supereruptions from 11 to 1 Ma. Understanding the timescales over which magma is stored in the crust prior to eruption is...

Evaluation of UWB techniques for indoor position locationing

Creator:: Chou, Tai Chian
Abstract:: Time of Arrival (TOA) is a popular technique used for geolocation. This thesis evaluates the use of TOA techniques indoors. The accuracy of measuring distances using TOA is dependent on the bandwidth of the system and the multipath conditions between the receiver and transmitter. System bandwidth has a significant effect...

The Geology, Geochronology, and Geochemistry of the Miocene Volcanic Rocks at the Inmaculada Ag-Au Mine, Southern Peru

Creator:: Cuellar Quispe, Juan Carlos
Abstract:: The Inmaculada Mine is located in the Miocene belt of epithermal deposits that extends from southern Peru to northern Chile and Bolivia. This belt is known for its silver-rich epithermal veins that have been worked since colonial times. The Inmaculada Mine belongs to a mining district that includes, from north...

Rhyolitic Melt Production in the Midst of a Continental Arc Flare-Up - The Heterogenous Caspana Ignimbrite of the Altiplano-Puna Volcanic Complex of the Central Andes

Creator:: Lewis, Charles T.
Abstract:: The ~5 km3, 4.54 to 4.09 Ma Caspana Ignimbrite of the Altiplano-Puna Volcanic Complex (APVC) of the Central Andes records the eruption of an andesite and two distinct rhyolitic magmas. It provides a unique opportunity to investigate the production of silicic magmas in a continental arc flare-up, where small volumes...

Mapping Minerals, Charting Community: A Petrographic Study of Dalma Ware in the Chalcolithic Near East

Creator:: Buehlman-Barbeau, Savanna S.
Abstract:: The recent recovery of Dalma Ware at the archaeological site of Surezha, Northern Mesopotamia (modern-day Iraqi-Kurdistan), has raised questions regarding the method of its arrival in the region (Stein 2017; Stein & Fisher 2018). In order to assess Dalma Ware’s potential modes of dispersal into Northern Mesopotamia, ceramic petrography and...

Volcanism and faulting along the northern margin of Oregon’s High Lava Plains : Hampton Butte to Dry Mountain

Creator:: Iademarco, Michael J.
Abstract:: Oregon’s High Lava Plains Province (HLP) has strongly bimodal basalt and rhyolitic volcanism. The Province caps the northern margin of the Basin and Range Province and serves as a transitional region between westward extension of the Basin and Range Province and unextended crust to the north . The High Lava...

The weather pattern and trends associated with Gulf Stream turbulent heat loss events

Creator:: Loyd, Nicholas
Abstract:: The weather pattern and trends associated with heat flux events (HFEs) over the Gulf Stream (GS) are examined as part of the CLIMODE project. A large portion of GS turbulent heat loss occurs during distinct synoptic scale events with a duration of one to two days. Forty percent (40%) of...
