GEO 448: Plate Tectonics.

5 hours (3, lecture; 2, lab), 4 credits. Plate Tectonics as a unifying theory: the driving mechanisms of crustal deformation. Evidence supporting sea-floor spreading and plate motions: geophysical and geologic data. Description and comparison of active and ancient tectonic belts. Implications of plate tectonics, continental drift, and mountain building, the role of plate tectonic cycle in renewal of Earth's surface, and relation with other biogeochemical cycles. Readings from original papers. Laboratories include geologic map study of older tectonic belts and techniques of measuring, plotting, and interpreting structural data of deformed rocks. PREREQ: GEO 166 OR 101 AND 167.
