Degree and scale of interactions among chiefdoms during the pre-Hispanic late period in northern Highland Ecuador (AD 1250-1525)

Creator:: Yanchar, Kaitlin C.
Abstract:: During the Late Pre-Hispanic period, settlements in Northern Highland Ecuador were organized under a number of chiefdoms. While a basic hierarchical political system is described in the ethnohistoric literature, the nature of the interactions between specific settlements has remained unknown. This study utilizes two methods for describing the degree and...

Lidar-based Post-earthquake Pavement Damage Classification System

Creator:: Shakya, Suzanna
Abstract:: 3D laser scanning has been used extensively in engineering reconnaissance surveys to capture perishable data in an efficient, reliable, and precise manner. Many insights on damage can be obtained from the data through various methods of post-processing; however, many of these techniques are often labor intensive. This delay reduces the...

Seismotectonics of the Himalayas and the Tibetan Plateau : moment tensoranalysis of regional seismograms

Creator:: Baur, Jan R.
Abstract:: This thesis presents a detailed seismotectonic investigation of the Himalayan region and the Tibetan plateau as part of project HiCLIMB to explore the state of stress and the kinematics of the world’s largest continental collision zone. Using full regional waveforms for moment tensor inversion, source parameters for 107 earthquakes were...

Olivine and plagioclase-hosted melt inclusions and their application to determining parental arc magmas

Creator:: Kohut, Edward John
Abstract:: Three broadly interrelated problems of critical significance to the proper interpretation of melt inclusion (MI) data are addressed in this thesis. The first issue, the petrogenesis of anorthitic plagioclase phenocrysts in MORB lavas, has relevance due to the presence of numerous MI in many high-An feldspars. This problem was addressed...

Structural Evolution, Vein Orientation, and Paragenesis of the Botija Porphyry Cu-Mo-(Au) Deposit, Colón, Panamá

Creator:: Sepp, Michael D.
Abstract:: The Botija Cu-Mo-Au porphyry deposit is located in the Cobre Panamá mining district, which contains several deposits with a global measure and indicated and inferred resource of 14.8 MT of Cu. These deposits are associated with the Cerro Petaquilla batholith, which has U/Pb zircon ages of 26-33 Ma (Whattam et...

Understanding large resurgent calderas and associated magma systems : the Pastos Grandes Caldera Complex, southwest Bolivia

Creator:: Kaiser, Jason Frederick, 1985-
Abstract:: The Pastos Grandes Caldera Complex (PGCC) in southwest Bolivia has produced two large-volume (≥800 km³ DRE) dacite ignimbrites from a nested caldera source over a period of 5.5 Myr. In addition to the large-volume ignimbrites, a small-volume ignimbrite shield and post-climactic lavas define this composite system. Based on detailed field...

Distinguishing between live and dead standing tree biomass on the North Rim of Grand Canyon National Park, USA using small-footprint lidar data

Creator:: Kim, YunSuk
Abstract:: Accurate estimation of live and dead biomass in forested ecosystems is important for studies of carbon dynamics, biodiversity, and wildfire behavior, and for forest management. Lidar remote sensing has been used successfully to estimate live biomass, but studies focusing on dead biomass are rare. We used lidar data, in conjunction...

Late Cenozoic Climate, Ice-sheet and Earth-surface Evolution Derived from Terrestrial and Marine Sedimentary Archives

Creator:: Bill, Nicholas S.
Abstract:: The goals of this dissertation are centered on understanding changes in Earth surface and climate systems through the use of geologic proxies as records of past changes in these systems. Specifically, this dissertation (1) establishes a new chronology for retreat of the Ross Sea sector of the West Antarctic Ice...

Heat Flow along the Southern Costa Rica Margin : Insights on the Updip Limit of Seismicity

Creator:: Hass, Bridget M.
Abstract:: Heat flow analysis of the Costa Rica convergent margin is carried out for seven core sites drilled during Integrated Ocean Drilling Program (IODP) Expeditions 334 and 344 as part of the Costa Rica Seismogenesis Project (CRISP). These expeditions were designed to develop a better understanding of erosional subduction zones. Heat...

Dynamics of the Laurentide Ice Sheet

Creator:: Carlson, Anders Eskil
Abstract:: This dissertation concentrates on the controlling factors on the instability of the Laurentide Ice Sheet (LIS) and their effects on abrupt climate change. Northern Hemisphere climate fluctuated abruptly during the last deglaciation possibly related to variability in Atlantic meridional overturning circulation (AMOC) and reduced aerial extent of the LIS. Reductions...
