Geology Major

Geology majors explore Earth systems and the environment, from the planet’s rocky surface and interior, to water in the hydrosphere, climate and the atmosphere, and the interplay between the biosphere and abiotic systems. Geology is the scientific study of Earth materials (such as minerals, rocks, and fossils) and planet-scale processes uncovered through Earth-observing data derived from satellites, geophysical instruments, and models. Geology coursework explains how past and present-day ecosystems and environments have been and continue to be shaped by plate tectonics, volcanism, mountain building, climate change, evolution, and human activity through time.

Major Requirements

The geology major typically starts with any 100-level Geology or geology-related Core SP courses, which typically counts towards the major as one of the five (5) additional full-credit GEOL courses below.

All majors must complete the following set of requirements:

All of the Following

GEOL 190 - Evolution of Planet Earth and
GEOL 190L
(ideally taken before the end of sophomore year)
GEOL 201 - Mineralogy and Geochemistry and
GEOL 201L
GEOL 215 - Paleontology of Marine Life and
GEOL 215L
GEOL 225 - Sedimentology and Surficial Processes and
GEOL 225L
GEOL 235 - Tectonics and Earth Structure and
GEOL 235L
Five (5) additional full-credit GEOL courses of which one can be at any level, at least 2 must be at the 300 level as listed below, at least 2 must be at the 400 level as listed below.

300-level Geology Electives

At least two courses from the following:

GEOL 301 - Igneous and Metamorphic Petrology and
GEOL 301L
GEOL 303 - Geochemistry
GEOL 310 - Environmental Economic Geology
GEOL 311 - Environmental Geophysics
GEOL 315 - Conservation Paleobiology
GEOL 320 - Techniques of Field Geology
GEOL 335 - Hydrology and Geomorphology and
GEOL 335L
GEOL 360 - Volcanology
Students are encouraged to consider taking a summer field course, such as
GEOL 320
, as one of their elective courses, as field experience is expected of some graduate programs and employment opportunities in the geosciences.

400-level Geology Electives

At least two courses from the following:

Two Additional Courses

Two full-credit courses in biology, chemistry, mathematics, or physics.

GEOG 245 - Geographic Information Systems

, may be taken in place of one of the required biology, chemistry, mathematics, or physics courses.

Capstone Experience

The two required 400-level courses provide a capstone experience for the geology major, as all such courses involve a significant project that integrates hypothesis testing, data collection and/or analysis of existing data, literature review, and a final project that synthesizes this work. A senior thesis conducted with an Earth and Environmental Geosciences faculty member as an adviser through GEOL 441 may count as one of the required 400–level courses and is required for all geology honors candidates. Students can initiate a senior research project of interest by speaking directly to a faculty member about ideas for a research project or by consulting with a faculty member about a project that might arise from a summer internship, a summer employment experience, or be based on research initiated in a departmental course.

GEOL 491

may not count towards the 400–level course requirement.

GPA Requirement

A GPA of 2.00 in the major is necessary for graduation. The ten full-credit courses that carry the highest grade are used to compute this average. A passing grade must be received in all courses counted toward the major.
