Lecture, laboratory, field trips. Offered in alternate years. The application of chemical principles to the study of the earth. Topics include natural solutions, construction and interpretation of activity and phase diagrams, stable isotopes, unstable isotopes and trace elements. Evidence bearing on the chemical evolution of the earth and the origin of important igneous rocks, chemical sediments and ore deposits is described.
Emphasis is placed on problem-solving and creative interpretation of data.
Offered in alternate years. The fossil record, evolution, morphology, adaptation and paleobiogeography of fish, amphi-bians, reptiles, birds and mammals. The interactions of vertebrates with ancient floras, climates and plate configurations will be emphasized. Offered in alternate years. Genesis and occurrence of igneous and metamorphic rocks, with emphasis on the behavior of magmas during cooling, the origin of crystalline rocks and the physico-chemical theories of metamorphism.
