GEOLSCI 262: Thermodynamics and Disorder in Minerals and Melts

Structural disorder in crystalline and glassy silicate solids, and in liquids, plays a profound role in their thermodynamic and transport properties. This course will integrate microscopic views of the structure of minerals, glasses, and melts with macroscopic properties such as entropy, enthalpy, density, diffusivity and viscosity. How properties are actually measured, and how uncertainties in measurement affect large-scale scientific conclusions, will be discussed. Spectroscopic (as opposed to diffraction) techniques for determining short-range structure will be emphasized, as will the relationship of such data to models of properties. Basic formulations for configurational entropy, heats of mixing, activities; and the energetics of exsolution, phase transitions, and nucleation will be introduced, as will the principles underlying geothermometry and geobarometry. A basic knowledge of thermodynamics and mineralogy will be assumed.
