The lithosphere-asthenosphere boundary is the world’s most ubiquitous plate boundary system, separating the high viscosity lithosphere from the underlying convecting mantle asthenosphere. Thoroughly characterizing the …
The lithosphere, the plate in ‘plate tectonics’, preserves a record of past and present tectonic processes in its internal structures and its boundary with the …
Thermal evolution of the planet interior is a fundamental problem in Earth and planetary sciences. Geothermobarometers and geospeedometers are powerful tools in studying the thermal …
While unstable on present-day Mars, liquid water was an important geologic agent in Mars' past. This work investigates the nature and timing of aqueous processes …
Impact cratering is a ubiquitous process affecting planetary surfaces in the solar system. The most probable impact angle is 45°, and ¼ of all impacts …
Stress-reduction, creep, grain-growth, and attenuation experiments were conducted on polycrystalline water ice to examine the links amongst microstructural steady-state, the mechanical response to transient loading, …
The objective of this thesis is to use first order geochemical and geophysical observations to understand melt generation and migration processes beneath mid-ocean ridge spreading …
Magmatism at the northern Antarctic Peninsula offers an exceptional opportunity to study the evolution of the Earth’s upper mantle in a region with an extensive …
The Andean Transitional Southern Volcanic Zone (34º-38ºS) represents an area of some of the most productive mafic volcanism in South America during the Cenozoic, making …
The interaction between crystals, magma, and exsolved volatiles in shallow magmatic conduits exerts first order controls on the eruptive style and intensity of terrestrial volcanic …
