The timing and evolution of Cenozoic extensional normal faulting in the southern Tobin Range, Pershing County, Nevada

Creator:: Gonsior, Zachary J.
Abstract:: The Tobin Range of central Nevada lies in the Basin and Range extensional province near the transition between more extended terrane (>50%) to the south and east, and generally less extended terrane to the north and west. Geologic mapping, 40Ar/39Ar dating and whole-rock geochemical analysis were employed to establish the...

Creating a Predictive Model of Cinder Cone Evolution in Central Oregon

Creator:: Das-Toke, Shyam P.
Abstract:: Cinder cones are useful geomorphic features for geological analysis because they generally have known initial states and follow a similar pattern of degradation as they are exposed to erosive processes. This is largely because cinder cones are produced by monogenetic eruptions. Characterizing large cinder cone fields in terms of age...

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...

Contrasting geomorphic responses to climatic, anthropogenic, and fluvial change across modern to millennial time scales, Clackamas River, Oregon

Creator:: Wampler, Peter J.
Abstract:: Geomorphic change along the lower Clackamas River is occurring at a millennial scale due to climate change; a decadal scale as a result River Mill Dam operation; and at an annual scale since 1996 due to a meander cutoff. Channel response to these three mechanisms is incision. Holocene strath terraces,...

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...

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...

Low-frequency Teleseismic and Infrasound Arrivals along the Dense Corvallis Nodal Array

Creator:: Way, Rachel
Abstract:: The dense Corvallis array deployed in January of 2022 aided in the high-resolution study of local geology. This array was made of 177 SmartSolo 3-component 5 Hz geophones around Corvallis, with a 93 geophone profile going west towards Bald Hill for approximately 5 km at an average of 64 m...

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...

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...
