A Semianalytical, Three Dimensional Model of Microstructure in Multiparticle, Multiphase Flow
(2011)
This dissertation presents a three dimensional microgeodynamic model of grain-melt geometry in partially molten rocks. The isotropic unit cell of the partially molten rock is characterized by a face-centered-cubic symmetry, ...
Quantification of Permeability-Porosity Relationships in Seafloor Vent Deposits: Dependence on Pore Evolution Processes
(2011)
Hydrothermal mineral deposits formed along seafloor spreading centers help regulate the transfer of heat and mass from Earth's interior to the oceans. Aqueous fluids circulate within the seafloor and are emitted through ...
STABILITY OF RIDGE-RIDGE-RIDGE TRIPLE JUNCTIONS BASED ON THE MECHANICS OF RIFT INTERACTION: THE NORTHERN GALÁPAGOS AND RODRIGUEZ TRIPLE JUNCTIONS
(2010)
Although known to be kinematically stable, Ridge-Ridge-Ridge (RRR) triple junctions sometimes display a complex sequence of short-lived rifts and no direct connection between the ridges. The Galápagos Triple Junction, in ...
Transport properties and melt distribution of partially molten mantle rocks: insights from micro-computed tomography and virtual rock physics simulations
(2015)
Mid-ocean ridges are a fundamental component of plate tectonics on Earth. They are the longest mountain ranges; combined, they stretch over 70,000 km of the Earth’s surface. They are significant sources of volcanism, ...
TECTONICS OF ICY SATELLITES DRIVEN BY MELTING AND CRYSTALLIZATION OF WATER BODIES INSIDE THEIR ICE SHELLS
(2015)
Enceladus and Europa are icy satellites that currently support bodies of liquid water in the outer solar system Additionally, they show signs of being geologically active. Developing numerical models informed by observations ...
Constraining Lithospheric Structure across the Continental Borderland using Receiver Functions
(2014)
Due to its complex history of deformation, which includes subduction, rifting, and transtensional motions, the California Continental Borderland provides an interesting geological setting for studying how the structure ...
Lithospheric Extension on Venus: how to form narrow rifts
(2017)
The Venusian rifts of Devana and Ganis Chasmata have been noted for their
similar morphology to some rifts on Earth (i.e., the East African rift system). These
are narrow rifts that are associated with localized deformation. ...
Inverse Spectral Methods in Acoustic Normal Mode Velocimetry of High Reynolds Number Spherical Couette Flows
(2016)
Experimental geophysical fluid dynamics often examines regimes of fluid flow infeasible for computer simulations. Velocimetry of zonal flows present in these regimes brings many challenges when the fluid is opaque and ...
CONSTRAINTS ON THE LITHOSPHERIC STRUCTURE OF MID OCEAN RIDGES FROM OCEANIC CORE COMPLEX MORPHOLOGY
(2016)
The Mid-oceanic ridge system is a feature unique to Earth. It is one of the fundamental components of plate tectonics and reflects interior processes of mantle convection within the Earth. The thermal structure beneath the ...
Evolution of strength and physical properties of ultramafic and carbonate rocks under hydrothermal conditions
(2016)
Interaction of rocks with fluids can significantly change mineral assemblage and structure. This so-called hydrothermal alteration is ubiquitous in the Earth’s crust. Though the behavior of hydrothermally altered rocks can ...
