Ge 11 a. Introduction to Earth and Planetary Sciences: Earth as a Planet. 9 units (3-3-3); first term. Systematic introduction to the physical and chemical processes that have shaped Earth as a planet over geological time, and the observable products of these processes—rock materials, minerals, land forms. Geophysics of Earth. Plate tectonics; earthquakes; igneous activity. Weathering, erosion, and sedimentary rocks. Metamorphism and metamorphic rocks. Rock deformation and mountain building. Role of aqueous, atmospheric, glacial, and tectonic processes in shaping Earth's surface and our environment. Earth resources. Field trips, interpretation of geological maps, and laboratory study of Earth materials (minerals and rocks).

Ge 115 b. Petrology and Petrography: Metamorphic Petrology. 6 units (3-0-3); third term. Prerequisite: Ge 115 a. The mineralogic and chemical composition, occurrence, and classification of metamorphic rocks; interpretation of mineral assemblages in the light of chemical equilibrium and experimental studies. Detailed consideration of structure, phase relations, composition, and determination of the major metamorphic minerals.

Ge 140. Introduction to Isotope Geochemistry. 9 units (3-0-6); second term. Prerequisite: instructor's permission. An introduction to the physics and chemistry of isotopes and a broad overview of the principles and conceptual techniques used in the stable isotope geochemistry of the lighter elements (H, C, O, N, Si, S) and the origin and evolution of radiogenic parent-daughter systems in nature.
