Earth & Planetary Sciences 7. Introduction to Geological Sciences
Catalog Number: 0918
Half course (fall term). M., W., F., at 10; three hours of laboratory work each week and two day-long field trips on separate weekends rquired. EXAM GROUP: 3

A course designed for concentrators but also appropriate for no-concentrators who desire a broad introduction to Earth science. Evolution of the Earth with an emphasis on the processes that have shaped our planet. The theory of plate tectonics is used to explain the occurrence and distribution of earthquakes, volcanoes and mountains. Labs and the weekend field trips familiarize students with rock types, geological features, and illustrate how geologists infer processes from the rock record. Note: Also appropriate for non-EPS concentrators who desire a comprehensive introduction to Earth science. This course, when taken for a letter grade, meet the Core area requirement for Science A.

Earth and Planetary Sciences 107. Environmental Geochemistry.
Catalog Number: 1242
Half course (spring term). Tu., Th., 11:30 - 1. EXAM GROUP: 13, 14

An overviewof low-temperature geochemistry through the treatment of a selection of geochemical issues of environmental significance. Each unit places geochemical topics in the context of a broader geological perspective with particular emphasis on chemical principles. Students from all concentrations are welcome. Note: Expected to be givein in 2005 - 2006. Given in alternate years. Prerequisite: A course in college-level chemistry or permission from the instructor.

Earth and Planetary Sciences 241. Istotope Geochemistry and the Evolution of the Earth's Interior.
Catalog Number: 1680
Half course (spring term). Hours to be arranged.

The composition of the Earth. Application of radiogenic and stable isotopes to study the processes of formation and evolution of the Earth's crust, mantle and core. Geochemical cycles of elements in the solid Earth. Geochemical cycles of elements in the solid Earth. Note: Expected to be given in 2005 - 2006. Given in alternate years.

Earth and Planetary Sciences 244. Noble Gas Geochemistry.
Catalog Number: 1573
Half course (spring term). Hours to be arranged.

Principles of noble gas geochemistry and geochronology and its application to specific problems in Earth and Planetary Sciences. Topics include surface exposure dating, (U-Th)/He and Ar-Ar thermochronometry, paleoclimatology, mantle evolution, and models of planetary atmosphere formation. Note: given in alternate years. Prerequisite: Intended for graduates and advanced undergraduate students involved in geochemistry research. Permission of instructor.
