Thermodynamics, Kinetics and Phase Equilibria

Thermodynamics in mineral sciences covers the stability of minerals and mineral assemblages as a function of pressure, temperature, and composition. Thermodynamic state functions such as enthalpy, entropy, and free energy will be discussed in detail to predict stable phases and parageneses. The concept of thermodynamic equilibrium will be explored.

In contrast, kinetics is the theoretical concept that allows us to qualitatively and quantitatively describe the processes (i.e., the mechanisms and rates) that form, alter and dissolve minerals and their synthetic analogues. Crystal surfaces are the critical players in fluid-solid (water-mineral) interactions. The course will provide an introduction to these topics.

Students will acquire the following knowledge and skills:
- understanding principle theoretical concepts of thermodynamics relevant for mineralogy and material sciences
- the importance of equilibrium and equilibrium thermodynamics
- phase stability and driving force of mineral reactions
- understanding the main concepts of mineral-fluid reaction kinetics (crystal growth, alteration, and dissolution)
- how do we measure and predict reaction rates correctly?
* Participants will learn how to judge (quantitatively) stability and reaction rates of minerals (and their synthetic analogues).
