Geology

Bachelor of Arts, Bachelor of Science

Geology is the study of the Earth and how it works. Specifically, geologists seek to answer questions as diverse as “How did this mountain form?” and “When will this volcano erupt again?” to “How do we provide clean drinking water?” Geologists work at the interface between human-kind and the Earth and are on the front line in solving a multitude of energy and environmental issues. Geologists use knowledge of math, chemistry, physics, and biology to answer these questions and gain first-hand experience working in the field. Graduates are employed by government agencies, such as the USGS and DEP, educational institutions, oil and mining companies, and environmental consulting firms.

Why Geology?

Students majoring in Geology will be preparing themselves to take an active role in the utilization of the earth's resources while protecting its fragile environment. Course work involves hands-on use of modern laboratory equipment and extensive projects out in the field. The faculty combines the use of small class sizes and abundant travel opportunities with a commitment to involving students in ongoing geological projects that involve both local and far-ranging locales. The curricula are designed with three primary objectives:

  • Prepare students for entry-level employment with consulting and industry that concentrates on environmental problems
  • Prepare students for entry-level employment in federal, state, and municipal environmental agencies
  • Prepare students to enter graduate programs in a branch of geology in preparation for a career in academia or upper-level employment with private companies or governmental agencies
  • The department offers courses leading to the Bachelor of Science (B.S.) or Bachelor of Arts (B.A.) degrees in Geology. To be recommended for graduation, students must earn at least a 2.5 GPA in their major. A student also must earn a grade of at least C in any Geology course that is taken to fulfill a degree requirement. One must earn at least a D in each required cognate

Fast Facts

  • The Geology department leads one large trip per year for students. Past trips have gone to Death Valley National Park, Yellowstone National Park, Costa Rica, as well as Italy and Greece
  • Geologists travel all around the world performing work at sea, on the top of mountains, in deserts, in underground caves, and in laboratories
  • Mercyhurst geology majors routinely present their original research at national conferences and have been internationally recognized for their efforts
  • The Mercyhurst Geology Club leads multiple field trips a year to go fossil and mineral collecting in Pennsylvania, Ohio, and New York
Majors

    Students pursuing a Bachelor of Science in Geology often go into research-heavy fields with an emphasis on direct application of geology principles. 

    Students pursuing a Bachelor of Arts in Geology often go into K-12 teaching and policy-related fields.

Minors
    • GEOL 100/102: Dynamic Earth & Lab (4 credits)
    • Four additional geology courses with at least three numbered 200 or higher are required
    • SCI 225: Oceanography may count towards the geology minor

Geology Facilities

    This room serves as our space for preparing rocks, minerals, fossils, and other geologic materials for teaching and research. The room features diamond saws, rock polishers, and a thin section machine for the study of rocks, as well as a Roto-Tap sieve shaker for measurement of coarse-grained sediment samples.

    This state-of-the-art geology smart classroom seats twenty-four students and includes an extensive rock and mineral collection for classroom use, petrographic microscopes for the study of thin section slides, and a library of geology-related textbooks.

    This classroom serves as our lab space for research and teaching in the geologic sub-disciplines of paleoclimatology and surficial processes. The space is equipped with two fume hoods for sample preparation, a muffle furnace for analysis of organic and inorganic carbon content, a Coulter Counter laser diffraction unit for the measurement of sediment grain size, our collection of topographic and physiographic maps, and a Darcy tube for groundwater flow demonstrations.
