Volatile cycling and the thermal evolution of planetary mantle
The thermal histories of terrestrial planets are investigated using two parameterized mantle convection models for either Earth like planets and planets with no active plate tectonics. Using parameterized models of mantle ...
Pore-Scale Controls on Permeability, Fluid Flow, and Methane Hydrate Distribution in Fine-Grained Sediments
Permeability in fine-grained sediments is governed by the surface area exposed to fluid flow and tortuosity of the pore network. I modify an existing technique of computing permeability from nuclear magnetic resonance (NMR) ...
Numerical Modeling of the Formation and Evolution of Basement-Involved Structures in Wyoming
The Wyoming foreland is composed of basement-involved structures and intermontane basins formed during the Laramide Orogeny. Based on their sizes, structures in this area can be categorized into primary uplifts and secondary ...
The origin and evolution of the deep lithosphere beneath continental arcs: constraints from lower crustal and mantle xenoliths from the Sierra Nevada, California
Lower crustal and upper mantle xenoliths from the Sierra Nevada continental arc in California, USA reveal a complex P-T-X-t (pressure-temperature-composition-time) evolution of the deep lithosphere. Metasedimentary ...
Response of the Texas coast to global change: Geologic versus historic timescales
The response of coastal systems to global change is currently not well understood. To understand current patterns and predict future trends, we establish a geologic record of coastal change along the Gulf of Mexico coast. A ...
