At Bryn Mawr: Geology, 2010-2011
Students may complete a major or minor in Geology. Within the major, students may complete concentrations in Environmental Studies, geoarchaeology or geochemistry.
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 from which the Earth is made; of the physical processes which have formed the Earth; of the history of the Earth and its organisms; and of the various techniques necessary to investigate Earth processes and the geologic record.
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.

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 (103-104) or PHYS (101-102 or 121-122); GEOL 399; 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 399) and write a thesis in the spring semester of her senior year.
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.
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.
The Environmental Studies concentration allows students to explore interactions of the geosphere, biosphere and human societies. The concentration represents interdisciplinary cooperation among departments in the natural and social sciences and humanities, and is open to students from any major, pending approval of the home department.
The Environmental Studies concentration in Geology consists of GEOL 101 and 103, 202 and two other 200 level geology courses, 302, 397, one other 300 level geology course and 399; CITY/SOCL 175, BIOL 220; two semesters of chemistry; and two semesters of math, statistics or computational methods. 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 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 the current director of Environmental Studies is advised in the planning of courses.
The Departments of Anthropology, Classical and Near Eastern Archaeology, and Geology offer a concentration in geoarchaeology for existing majors in these departments. Please consult with Professor Magee regarding this program.
Requirements for the concentration:
- Two 100 level units from Anthropology, Classical and Near Eastern Archaeology or Geology, of which one must be from the department outside the student's major.
- ANTH/ARCH/GEOL 270: Geoarchaeology (Magee, Barber).
- BIOL/ARCH/GEOL 328: Geospatial Data Analysis and GIS (staff).
- Two elective courses, to be chosen in consultation with the major adviser, from among current offerings in Anthropology, Classical and Near Eastern Archaeology and Geology.
One of these two courses must be from outside the student's major. Suggested courses include but are not limited to ANTH 203 (Human Ecology), ANTH 220 (Methods and Theory), ANTH 225 (Paleolithic Archaeology), ANTH 240 (Traditional Technologies), ARCH 308 (Ceramic Analysis), ARCH 332 (Field Techniques), GEOL 202 (Mineralogy), GEOL 205 (Sedimentology), GEOL 310 (Geophysics), and GEOL 312 (Quaternary Climates).
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; 302 or 305; CHEM 101 or 103, 104 and 221 or 222. Additional chemistry courses might include 211 (Organic 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 Pedro Marenco or Lynne Elkins (Geology) or Sharon Burgmayer (Chemistry).
