EART 130. Magmas and Volcanoes.
Introduction to the relationship between tectonic environments and the genesis of rock assemblages, primarily igneous and metamorphic. Examples from California and elsewhere are used to illustrate petrogenetic processes and characteristic petrologic features of rocks from all major tectonic settings. Will be offered in the 2001-02 academic year. Prerequisites: course 110B. (Formerly California Rocks and Tectonics.)

EART 209. Solid Earth Geochemistry.
Origin and distribution of the elements in the earth and meteorites; bulk and isotopic composition and differentiation of terrestrial planets, core, mantle, and crust; Sr-Nd-Pb-Hf-U isotopic tracers. Course designed for graduate students, but available to qualified earth sciences majors per instructor permission. Enrollment restricted to graduate students. (Formerly 208.)

EART 290D. Petrology and Plate Tectonics.
Selected topics illustrating relationships between igneous and metamorphic rocks and plate tectonics are explored in detail. Designed for graduate students but available to qualified Earth sciences majors. Offered in alternate academic years. May be repeated for credit.

ENVS 152. Science and Land Use Decisions.
Technical and policy dimensions of major land use decisions will be assessed through a detailed case study. Technical review will stress geological constraints; policy review will stress the CEQA process. The initial case study will be the reuse of Ford Ord. One field trip is required. Prerequisites: one of course 140, 149, 151 (recommended), or 165; and one of Earth Sciences 20 (recommended), 1 or 5.
