GEOLSCI 260: Quantifying Uncertainty in Subsurface Systems

Broad conceptual overview of the various components required to uncertainty quantification (UQ) for decision making in subsurface engineering problems such as oil/gas production, groundwater management, contaminant remediation, geothermal energy and mineral deposits. The emphasis lies on learning how to synthesize rather than the details of each individual discipline. The class will cover the basic data science for UQ: dimension reduction methods, Monte Carlo & global sensitivity analysis. Introduction to Bayesianism and how it applies to subsurface prediction problems, in particular, the formulation of geological prior models and the role of geostatistics. Strategies for integrating geological science, geophysics, data science and decision science into decision making under uncertainty. Team work on real field applications.

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.

GEOLSCI 280: Igneous Processes (GEOLSCI 180)

For juniors, seniors and beginning graduate students in Earth Sciences. Structure and physical properties of magmas; use of phase equilibria and mineral barometers and thermometers to determine conditions of magmatic processes; melting and magmatic lineages as a function of tectonic setting; processes that control magma composition including fractional crystallization, partial melting, and assimilation; petrogenetic use of trace elements and isotopes. Optional labs emphasize identification of volcanic and plutonic rocks in thin section and interpretation of rock textures. Students taking the lab component should enroll in 4 units, as required for the Geological Sciences major; for the lab, GS 102, 103, or consent of instructor are prerequisites.

GEOLSCI 283: Thermochronology and Crustal Evolution

Thermochronology analyzes the competition between radioactive in-growth and temperature-dependant loss of radiogenic isotopes within radioactive mineral hosts in terms of temperature-time history. Coupled with quantitative understanding of kinetic phenomena and crustal- or landscape-scale interpretational models, thermochronology provides an important source of data for the Earth Sciences, notably tectonics, geomorphology, and petrogenesis. Focus on recent developments in thermochronology, specifically analytical and interpretative innovations developed over the past decade. Integrates the latest thermochronology techniques with field work in a small-scale research project focused upon crustal evolution.
