Students who major in geology at Saint Louis University study Earth’s physical structure and formation. You’ll decipher history from rock record, locate natural resources, identify hazards and understand our planet’s natural processes.

Major in Geology

At SLU, you can choose between a Bachelor of Arts or a Bachelor of Science degree in geology. Both are offered by the Department of Earth and Atmospheric Sciences and study earth processes, rocks, minerals and structures. The B.S. degree, however, places a stronger emphasis on chemistry, physics and calculus. Pick this degree if you intend to go on to graduate school or become a professional geologist.

All undergraduate geology students at SLU begin their studies with survey courses in Earth systems, classes that focus on the building blocks of the planet and the processes that change its features. You’ll learn about erosion, sediment transport, the development of mountain ranges and the movement of tectonic plates.

You’ll also develop your social and leadership skills through course-related laboratory exercises and day, weekend and weeklong field trips.

Geology students enrolled in our Bachelor of Science program also participate in a six-week summer camp where they learn to work in the field. These students also have the opportunity for part-time work assisting faculty members with their geology research.

Internships and Careers

Students who graduate with a major in geology from Saint Louis University are prepared to work as geoscientists or for government agencies concerned with oil and natural gas exploration and production, mining, water resources, civil engineering or waste and pollution management.

You may also use your skills providing environmental impact assessments, conservation and land management or policy analysis.


Faculty teaching in SLU’s geology program are devoted to the training of students in the classroom, laboratory and field. Faculty members are involved in research domestically and in field areas as far away as Antarctica and Asia. They then bring those experiences back into the classroom to enrich the learning experiences of their students.

Minor in Geology

SLU also offers a 20-credit-hour minor in geology. Students must take Earth Systems I and II and Mineralogy, as well as each course's respective lab. Field Techniques in Geology and a minimum of six credit hours in elective courses complete this minor.

Real-World Experience

Annual Geology Field Trip

During the annual geology department field trip, faculty, graduate and undergraduate students spend one week exploring a region of the United States. Students travel through national parks, see natural systems and learn firsthand about the Earth and its environment. SLU's Department of Earth and Atmospheric Sciences heavily subsidizes these trips so that most students can participate.
