Zhao, Yan (2005-12-20)Department: MathematicsAn ordinary differential equations model for strep throat infection is constructed to compute the bacterial population densities of genotype combinations with binary switches in contingency genes. Theoretical analysis for ...
-
Fisher, Christopher Michael (2006-07-31)Department: GeologyNew whole-rock Pb isotopic data combined with existing Pb, Sm-Nd, and U/Pb zircon data from the Blue Ridge and the Mid-Continent Granite Rhyolite terrane support recent suggestions that the southern and central Appalachian ...

Banik, Tenley Jill (2015-07-21)Department: Environmental EngineeringTiming and duration of magmatism, involvement of fluid or assimilation of material, and geodynamic context are all important when assessing the processes by which silicic magmas are produced, erupted, or emplaced. This ...

Fathel, Siobhan L. (2016-11-11)Department: Environmental EngineeringBed load sediment particles move as complex motions over the surface of a stream bed, accelerating and decelerating in response to the near-bed turbulence and due to particle-bed interactions. Detailed measurements of ...
-
McDowell, Susanne Mathilde (2014-07-22)Department: Environmental EngineeringSilicic magmas pose threats to society in the form of explosive volcanism. Understanding silicic magmatism is thus crucial for evaluating eruption-related risks, but numerous questions are unresolved: How are silicic magmas ...

Walker, Jr., Barry Alan (2006-04-17)Department: GeologyThe Spirit Mountain batholith (SMB) is a ~250 km2 composite silicic intrusion located within the Colorado River Extensional Corridor (CREC) in southernmost Nevada. Westward tilting of 40-50º has exposed a cross section ...
-
Banik, Tenley Jill (2008-05-14)Department: Earth and Environmental SciencesIn the Siða-Fljotshverfi District of south Iceland, Pleistocene basaltic lava forms flame-like apophyses, dikes, and disaggregation structures that invade overlying hyaloclastite. Apophyses as well as underlying lavas are ...
-
Crombie, Scott Andrew (2006-08-01)Department: Earth and Environmental SciencesWe consider the response of monazite in country rock to magmatic intrusion. Intrusion of the Searchlight pluton at 15.7-17.7 Ma produced extensive hydrothermal ore deposits in overlying units. Later tilting of the pluton ...

Carley, Tamara Lou (2010-07-16)Department: Earth and Environmental SciencesThis two-part study is focused on the evolution of silicic magma in two very different settings. The first part is a study of zircon to understand the generation, storage, and evolution of felsic magmas erupted in historical ...
-
Foley, Michelle Lee (2017-07-27)Department: Earth and Environmental SciencesThe ~1000 km3 Peach Spring Tuff (PST) is the product of an 18.8 Ma supereruption from Silver Creek caldera, southern Black Mountains, AZ (Ferguson et al 2013). Five zones are recognized in thick outflow sections of the ...
-
Carley, Tamara Lou (2014-07-22)Department: Environmental EngineeringIceland’s great abundance of silicic rock (10-13% of subaerial exposures), coupled with the unusual thickness of the island’s crust, hints at continental nucleation and permanent crust construction in an oceanic environment. ...
-
Claiborne, Lily Lowery (2006-07-31)Department: GeologyZirconium and Hf are nearly identical geochemically, and therefore most of the crust maintains near chondritic Zr/Hf ratios of ~35-40. By contrast, many high-silica rhyolites and granites have anomalously low Zr/Hf (15-30). ...
-
Claiborne, Lily Lowery (2011-04-06)Department: Environmental EngineeringThe processes by which magma is transported into, stored within, and expelled (erupted) from the upper crust are critical to understanding volcanism and crustal construction. Recent studies suggest that magmatic systems ...
-
Padilla, Abraham De Jesus (2011-08-08)Department: Earth and Environmental SciencesThis study aims at understanding the processes by which silicic magmas are generated, how silicic magmatic systems evolve and how they are terminated, and the link between magmatic processes at depth and eruptive centers ...
