An introduction to the ideas and approaches of earth and environmental sciences, including both the special challenges and viewpoints of these kinds of science as well as the ways in which basic physics, chemistry, and biology relate to them. In addition to a wide-ranging lecture-oriented component, there will be a required field trip component (two weekend days). The lectures and topics cover such issues as solid earth structure and evolution, plate tectonics, oceans and atmospheres, climate change, and the relationship between geological and biological evolution.
GE 106: Introduction to Field and Structural Geology
12 units (3-6-3) or 6 units (1-4-1); third term. Prerequisite: Ge 11 ab. The 6-unit option introduces methods of geologic mapping and is required for all students planning to take Ge 120. Geology majors must enroll for 12-unit option, which additionally introduces continuum mechanics, interpretation of deformed rocks, and the tectonics of mountain belts.
GE 121b: Advanced Field and Structural Geology
12 units (0-9-3); second term. Prerequisites: Ge 11 ab and Ge 120 or equivalent, or instructor's permission. Field mapping and supporting laboratory studies in topical problems related to southern California tectonics and petrogenesis. Each year the sequence offers a breadth of experience in igneous, metamorphic, and sedimentary rocks.
GE 270: Continental Tectonics
9 units (3-0-6); first term. Prerequisites: ACM 95/100 or ACM 113; Ge 11 ab, Ge 106, Ge 162, Ge 166, or Ge 161. Nature of non-plate, finite deformation processes in the evolution of the continental lithosphere using the Alpine orogen as an example. Rheological stratification; isostatic and flexural response to near-vertical loads; rifting and associated basin development; collision and strike-slip tectonics; deep crustal processes.
