Geology

Students may complete a major or minor in Geology. Within the major, students may complete concentrations in environmental studies, geoarchaeology or geochemistry.

Faculty

Donald C. Barber, Associate Professor (on leave 2006-07)
Blythe L. Hoyle, Lecturer and Laboratory Coordinator
Christopher Oze, Assistant Professor
Catherine A. Riihimaki, Keck Postdoctoral Fellow
W. Bruce Saunders, Professor and Chair
Arlo B. Weil, Assistant Professor

The department seeks to make students more aware of the physical world around them and of its development through time. The subject includes a study of the materials of which the Earth is made; of the physical processes which have formed the Earth, especially near the surface; of the history of the Earth and its organisms; and of the various techniques necessary to investigate Earth processes and history.

Each introductory course is designed to cover a broad group of topics from a different perspective. Students may elect any of the 100-level courses. Fieldwork is an essential part of geologic training and is part of all introductory courses, most other classes and most independent research projects.

Major Requirements

Thirteen courses are required for the major: GEOL 101 and 102 or 103; 202, 203, 204, and 205; MATH 101 and 102, or alternates approved by the adviser; a two-semester sequence of CHEM (101/103-104) or PHYS (101-102); GEOL 403; and either two advanced geology courses or one advanced geology course and an additional upper-level course in biology, chemistry, mathematics, physics, or computer science.

Additional courses in the allied sciences are strongly recommended and are required by most graduate schools. A student who wishes to follow a career in geology should plan to attend a summer field course, usually following the completion of the 200-level courses.

All geology majors undertake a research project (GEOL 403) in the senior year. Most students complete a one-semester project in the fall semester; a two-semester project may be undertaken with approval of the department.

Honors

Honors are awarded to students who have outstanding academic records in geology and allied fields, and whose research is judged by the faculty of the department to be of the highest quality.

Minor Requirements

A minor in geology consists of two of the 100-level Geology courses, and any four of the 200- or 300-level courses offered by the department.

Concentration in Environmental Studies

The environmental studies concentration allows students to explore interactions of the geosphere, biosphere and human societies. The concentration represents interdisciplinary cooperation among the departments of anthropology, biology, economics, English, geology, political science and growth and structure of cities, and is open to students majoring in any of these departments.

The environmental concentration in geology consists of GEOL 101 and 103, 202 and two other 200-level geology courses, 328, 397, one other 300-level geology course and 403; BIOL 220; CHEM 101 or 103, and 104; and two semesters of math, statistics or computational methods. Students starting the concentration in Fall 2006 must take CITY 175 Environment and Society. Two additional environmental courses outside of the natural sciences also are required: one addressing issues of planning and policy, and one that addresses issues of humans in the environment. The environmental studies Web site (http://www.brynmawr.edu/es/core.htm) lists approved courses in these categories. Paperwork for the concentration should be filed at the same time as the major work plan. Students also should carefully consider their options with regard to study abroad in the junior year. Early consultation with Don Barber and the director of environmental studies is advised in the planning of courses.

Concentration in Geoarchaeology

The geoarchaeology concentration allows students majoring in anthropology, archaeology or geology to explore the connections among these fields with respect to how our human ancestors interacted with past environments, and how traces of human behavior are preserved in the physical environment. In geology, the geoarchaeology concentration consists of 13 courses: GEOL 101 or 102 or 103, 202, 205, 270, 328, another 200- or 300-level geology course, and 403: CHEM 101 or 103, and 104; two semesters of math, statistics or computational methods; either ARCH 101 or ANTH 101; and one 200- or 300-level elective from among current offerings in Anthropology or Classical and Near Eastern Archaeology. Paperwork for the concentration should be filed at the same time as the major work plan. For course planning advice, consult with Don Barber (Geology), Rick Davis (Anthropology) or Peter Magee (Archaeology).

Concentration in Geochemistry

The geochemistry concentration encourages students majoring either in geology or in chemistry to design a course of study that emphasizes earth chemistry. In geology this concentration includes at least: GEOL 101, 103, 202, 205; one of 301 or 302 or 305; CHEM 101 or 103, 104 and 231 (Inorganic Chemistry). Additional chemistry courses might include 211 (Organic Chemistry) or 222 (Physical Chemistry). Other courses that complement this concentration are: calculus, linear algebra, computer programming and computer modeling. Paperwork for the concentration should be filed at the same time as the major work plan. For course planning advice, contact Christopher Oze (Geology) or Sharon Burgmayer (Chemistry).
