GE231 Structural Geology

Course Description

Structural geologists study of the geometry of geologic structures (such as faults, folds, joints, intrusive bodies, ect.), how these structures form, their significance to the geologic history of an area, and their relationship to plate-tectonic motions. In my opinion, a basic course in structural geology should: 1) enable you to evaluate a suite of geologic structures in order to draw conclusions about their formation and their significance to the geologic history of an area, 2) enable you to apply basic structural analysis techniques to solve problems in a variety of geoscience disciplines, and 3) help you develop the three-dimensional thinking skills needed to evaluate subsurface geology using two-dimensional, surficial data sets. In addition to these three primary goals, this course also aims to improve graphical and written communication skills.
