EOS 2020/ENVS 2250. Earth, Ocean, and Society

Explores the historical, current, and future demands of society on the natural resources of the earth and the ocean. Discusses the formation and extraction of salt, gold, diamonds, rare earth elements, coal, oil, natural gas, and renewable energies (e.g., tidal, geothermal, solar, wind). Examines how policies for these resources are written and revised to reflect changing societal values. Students complete a research project that explores the intersection of natural resources and society.

EOS 2165. Mountains to Trenches: Petrology and Process

Exploration of the processes by which igneous rocks solidify from magma (e.g., volcanoes) and metamorphic rocks form in response to changes in pressure, temperature, and chemistry (e.g., mountain building). Interactions between petrologic processes and tectonics are examined through a focus on the continental crust, mid-ocean ridges, and subduction zones. Learning how to write effectively is emphasized throughout the course. Laboratory work focuses on hand sample observations, microscopic examination of thin sections, and geochemical modeling.

What processes control the evolution of mountain belts in time and space? What is the role of disequilibrium during metamorphism? How do micro- and nano-scale processes influence plate-tectonic-scale processes, such as collisional orogenesis and the exhumation of terranes? To address these questions, I use petrology, mineralogy, geochronology and geochemistry to quantify the timing and rates of metamorphic recrystallization, deformation, melting and other aspects of crustal evolution. My research has focused on developing in situ techniques to measure pressure, temperature and time, while retaining the petrologic context.
