A general kinetic model: Kinetics and atomic-scale mechanisms of feldspar dissolution
This thesis presents a general kinetic model and its application to feldspar dissolution. In the framework of Monte Carlo methods, the model simulates the stochastic processes of feldspar dissolution by incorporating bond ...
Resolving the nanoscale mechanisms of calcite growth and dissolution from nonstoichiometric and microbial solutions
The relative rates of calcite (CaCO3) precipitation and dissolution largely determine the preservation and subsequent accumulation of carbonate in the geologic record and are fundamental parameters for predicting the fate ...
Accumulation of gas hydrates in marine sediments
Generalized numerical models for simulating gas hydrate and free gas accumulation in marine sediments have been developed. These models include several physical processes such as phase equilibrium of gas hydrates, multiphase ...
Redox state and water content in the upper mantle: Linkages to the atmosphere, hydrosphere and continents
Geochemical and petrologic tools were deployed to investigate the redox state and water content of the earth's upper mantle. Study results are discussed in the context of their linkages to the atmospheric oxygen level, ...
Fluid relationships in the Northern Gulf of Mexico using dissolved ion concentrations and strontium isotopes
Pore fluids from the slope in the Gulf of Mexico demonstrate specific ion enrichment and a range in concentration. Dissolved metal and halogen fluid concentrations and strontium isotope ratios from ten sites on the Gulf ...
