This dissertation explores the recent history of non-polar ice-rich paleodeposits on Mars, primarily through the analysis of pedestal craters. Pedestal craters are defined by having …
The history of Mars’ paleoclimate is explored using sedimentary records from both the Noachian and Amazonian periods. Sedimentary structures indicative of a progradational delta are …
Under the current paradigm of Mars history, the planet is thought to have undergone a global climatic change, from relatively warm and wet conditions during …
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 …
This thesis studies the shergottite family of martian meteorites using a variety of experiments performed on natural and synthetic samples. The study determines the crystallization …
The climatic history of Mars has been indirectly studied through the remote detection of minerals produced by chemical alteration across its surface. While the martian …
Orbital and landed investigations of Mars have revealed a variety of secondary minerals on the surface consistent with past surface or subsurface liquid water and …
Valley networks, many connecting voluminous paleolakes, dissect the martian highlands, but ceased activity ~3.7 billion years ago. The nature of the climate that allowed so …
Thermal contraction crack polygons, gullies, and glacial surfaces are ubiquitous features of polar terrains on Earth and Mars. The morphology of these cold-desert landforms is …
Sulfates are important secondary minerals produced from the evaporation of fluids involved in the aqueous alteration of Mars' primary lithology [Tosca et al. 2005]. Sulfates …
Explosive volcanic eruptions are common on the terrestrial bodies of the Solar System. The modeling of explosive volcanic eruptions and the pyroclastic deposits they produce …
