Description

Students may complete a major or minor in Geology. Within the major, students may complete concentrations in 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 that 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.

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 (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.

Concentration 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, 203, 204, 205, 270 and 399; two semesters of chemistry; 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; 302 or 305; and CHEM 101 or 103, 104 and 221, or 222. Additional chemistry courses might include 211 (Organic Chemistry).

GEOL B115 Living with Volcanoes

L. Elkins
This course explores how people have long lived alongside, in the shadow of and, at times, directly on top of active volcanoes. Volcanic centers are hosts to sporadic and difficult-to-predict destructive and explosive activity, persistent and damaging passive degassing, vibrant ecosystems and important geothermal energy systems. The goals of this class are to examine the scientific basis for understanding volcanoes and predicting their behavior; to study the role of volcanoes in history and lore across human societies; and to examine our complicated relationship with them in the modern world. Prerequisite: Freshman standing. Not offered in 2011-12.

GEOL B120 Origin and Early Evolution of Life

K. Marenco
Where and how did life originate on Earth? What are the minimum conditions for life to arise, and persist, on any planet? Scientists are closer now than ever before to answering these intriguing questions. In this course, we will explore the fundamental requirements for life; critically examine many of the hypotheses that have been proposed to explain the origin of life on Earth; survey the fossil, geochemical and molecular evidence for early life, from the earliest-known examples through the “Cambrian Explosion;" and propose means of identifying life and its effects elsewhere in the universe. Two lectures per week, plus a one-day fieldtrip. Not offered in 2011-12.

GEOL B125 Geology in Film

P. Marenco
Geologic processes make for great film storylines, but filmmakers take great liberty with how they depict scientific Ÿfactsˆ and scientists.

Prerequisite: Freshman standing.

GEOL B130 Life in the Hothouse: Earth’s Future Climate
