Advanced Tectonics
Prof. M.O. Withjack. [Prerequisite: Structural geology.] The goal of the course is to study (1) the diversity of structural styles and tectonic settings worldwide using outcrop, well, and seismic data; (2) the results of geometric and experimental modeling; and (3) restoration techniques.
