This module is designed to make the student conversant in the basic principles of aqueous geochemical and reactive transport. The fundamental concepts of the law of mass action and mineral solubility will be introduced. Chemical transport mechanisms, notably advection and diffusion will be presented. Specific examples of mineral dissolution/precipitation kinetics will be reviewed. Methods to solve the equations describing reactive chemical transport will be presented including finite difference and finite element methods. Training in the use of widely distributed geochemical modeling software will be provided and these tools applied to natural systems including chemical weathering, carbon/waste storage and ore formation.
The student will become conversant in modern methods to quantify in time and space the rates and consequences of mineral-fluid reactions and chemical transport in natural systems.
