Geological Sciences Program

The goal of Hardin-Simmons Department of Geology is to teach our students a solid foundation in the various geoscience disciplines. Our department provides fundamental training for career geoscientists and introduces a basic understanding of the geological sciences for our liberal arts student. Our program is designed to prepare students for graduate school and professional work.

Why study Geology & Environmental Sciences at HSU?

Field Research

Our programs have a strong field component providing hands-on learning opportunities across the United States. Our programs have visited the California coast, the Grand Canyon, the Rocky Mountains, the Rio Grande Rift, the Arbuckle Mountains, and more!

Personal Attention

Our small class sizes provide students with many opportunities to learn from faculty both inside and outside of the classroom. Your professors will know your name, are invested in your success, and can add great depth to letters of reference or recommendation!

Excellent Outcomes

More than 90% of our majors have a job in the field within five years of graduation. Students moving on to graduate programs have a 95% acceptance rate at major universities in Texas, Louisiana, and Oklahoma. About 60% of our graduates are admitted to the HSU Environmental Management Master of Science program.

Program Details

The Bachelor of Science in Geological Sciences

The Bachelor of Science in Geological Sciences major requires a minimum of 41 semester credits (29 of which must be upper-level courses in Geology). A Bachelor of Science degree is recommended for students interested in pursuing a career in the geological sciences, to sit for the ASBOG examination, or to pursue a graduate degree in geology/geological sciences.

Courses required include GEOL 1303, 1103, 1411, 2410, 3311, 3405, 3410, 3411, 4144, 4312, 4315, 4410, and three credits of upper-division electives selected from GEOL 3101, 3102, 3103, or 4104.

Required supporting courses include: CHEM 1310, 1110, 1311, 1111, PHYS 1310, 1110, 1311, 1111; one of two mathematics options as either MATH 1420, 1421 and MATH 3312, or MATH 1310 and 1311, and STAT 3312. The minor in Environmental Science is recommended.

The student also has the option of a minor in biology, chemistry, computer science, or mathematics.

A major in Geology must pass all required and elective Geology and supporting courses with grades of “C” or better in order for the Department Head to certify that a student has been offered the academic background needed to sit for the ASBOG examination. The ASBOG examination is rigorous. A student who anticipates sitting for the examination should work to earn the highest grades possible in all Geology and supporting courses. This gives the student the best potential to pass the examination.

  • Prepare students to sit for the Association of State Boards of Geology (ASBOG) examination (Certified Professional Geologist)
  • Prepare students for graduate school and professional work
  • Our graduates are working to produce energy for our world and to make our world a cleaner place
