Geological Sciences < University of Colorado Boulder

Programs Offered

Bachelor's Degree

Geology - Bachelor of Arts (BA)

Minor

Geology - Minor

The options available in the undergraduate program in geological sciences are geology and geophysics and lead to the BA degree. Both options provide a strong basis for understanding the functioning of the Earth system. Students who are uncertain as to which option best suits their needs should contact a departmental advisor or faculty mentor. In each option, the undergraduate program emphasizes coursework in theoretical, laboratory and field-oriented aspects of the geological sciences. The nearby Rocky Mountains provide a natural laboratory for many of these courses.

Students interested in the geological sciences may also wish to consider the Baker Residential Academic Program (see the Undergraduate Residential Programs section). Students who do not wish to pursue a career in the geosciences, or who would like to combine a basic knowledge of geologic sciences with that of some other field, should consider a minor in geological sciences. Students who intend to pursue graduate study in the geological sciences are encouraged to consider developing an honors thesis as part of their undergraduate studies.

The two options available in the undergraduate major offer different focus areas of instruction. Both options offer excellent preparation for students interested in pursuing professional careers, or graduate study, in the geological sciences.

Each option emphasizes knowledge in:

The ways in which Earth responds to internal and external forces; the physical, chemical and biological evolution of Earth; and the nature of the materials of which the Earth is made.
The role of physics, chemistry, mathematics and biology in understanding geological processes.
The history of discoveries and ideas that have contributed to our current knowledge of Earth and the planetary system.

Course code for this program is GEOL.

Geology Honors Program

Opportunity is provided for qualified geology majors to participate in the geology honors program and graduate with honors (cum laude, magna cum laude or summa cum laude) in geology. Students interested in the honors program should contact the departmental honors advisor during their junior year.

Professional Licensure

The State of Colorado does not require individuals working in Geology or the Geological Sciences to obtain Professional Geology Licensure, however many states require professional geologists to pass the ASBOG Fundamentals of Geology (FG) and/or Practice of Geology (PG) examinations. Information regarding ASBOG examination specifications can be found at the ASBOG website.

Students planning to seek professional licensure or certification for employment in a state other than Colorado, are strongly recommended to contact the appropriate licensing entity in the state in which they are, or plan to be, located in order to seek information and guidance regarding licensure or certification requirements and how the education received at CU Boulder may assist the student in their efforts to gain licensure in that state.

Faculty

While many faculty teach both undergraduate and graduate students, some instruct students at the undergraduate level only. For more information, contact the faculty member's home department.
