Late cretaceous ocean circulation in the south Atlantic and Pacific oceans
(University of Missouri--Columbia, 2019)
with deep ocean convection in high latitude regions (e.g., Robinson et al., 2010; MacLeod et al., 2011; Robinson and Vance, 2012; Jung et al., 2013). Understanding the relationship between climate change and sub-surface ocean circulation patterns...
On the ability of rocks to conduct heat in the Lithosphere
(University of Missouri--Columbia, 2019)
This work focuses on creating a model for the conductive thermal transport properties of rocks using measured thermal diffusivity (D) with the Laser Flash Analysis (LFA) method, which eliminates common errors associated ...
Temporal trends in the Holocene: exploring implications for conservation paleobiology through quantitative assessment of marine mollusks
(University of Missouri--Columbia, 2018)
Conservation paleobiology is a relatively new field which applies the theories and analytical tools of paleontology to problems concerning the conservation of biodiversity. The use of data from stratigraphy, sediment or ...
Fluid inclusion evidence for the temperature and composition of ore fluids in the Lemhi Pass and diamond Creek Ree-Th districts, Idaho-Montana
(University of Missouri--Columbia, 2019)
The Lemhi Pass district is the largest thorium (Th) and 5th largest rare earth element (REE) occurrence in the U.S., straddling the continental divide along the central Idaho-Montana border. The Diamond Creek district, ...
Structural geology, tectonic geomorphology, and neotectonics of the central Afar Rift, Ethiopia and Djibouti
(University of Missouri--Columbia, 2018)
The central Afar depression offers an opportunity for quantitative analysis of the final stages of continental breakup at a divergent triple junction. Here, Quaternary faulting dissects Plio-Pleistocene flood basalts, ...
Investigations of Mississippi valley-type mineralizing fluids via analytical geochemistry, numerical modeling, and experimental geochemistry
(University of Missouri--Columbia, 2021)
Mississippi Valley-type (MVT) deposits represent enrichments of base metals and other elements up to 1000's of times greater than their average concentrations in the Earth's crust. These enrichments most commonly consist of Zn and Pb as the minerals...
Resolving space-time strain paths of the Panamint and Cottonwood Mountains, eastern California, through bedrock thermochronology and detrital geochronology
(University of Missouri--Columbia, 2020)
The landscape in Death Valley region is the result of a complex history that includes Miocene Basin and Range extension and Miocene to recent transtension. Despite being one of the best studied regions in the world, ...
The effects of volatiles on the viscosity and heat capacity of calc-alkaline basaltic and basaltic andesite liquids
(University of Missouri--Columbia, 2014)
Calc-alkaline basaltic magmas are volumetrically important at continental and island volcanic arcs, yet their thermal and physical properties are poorly described. These basaltic magmas are characteristically hydrous, and ...
Regional site response and uppermost mantle seismic structure of central and eastern united states
(University of Missouri--Columbia, 2019)
This dissertation examines seismological data from regional earthquake sources in order to examine the seismological character of the crust and uppermost mantle in central and eastern United States. Firstly, site amplification ...
Atypical planetary lavas: rheological evolution of cooling and crystallizing flows from lunar impact melts and cryovolcanic processes
(University of Missouri--Columbia, 2021)
as analog cryolavas to measure their viscosity. I developed a new viscosity model, based on the Vogel-Fulcher-Tammann (VFT) equation commonly used in silicate rheology, to predict viscosity of aqueous solutions a function of both temperature...
Taphonomic characteristics of fossils on the burgessshale-type spectrum
(University of Missouri--Columbia, 2018)
"Study of exceptional fossil preservation tends to yield exciting results. Since soft-bodied organisms and the soft tissues of biomineralizing organisms are usually not preserved in the fossil record, instances of soft-tissue ...
