Steven D. Sheriff, Chairman

An understanding of geology involves a knowledge of the processes and events that shape the earth. By studying minerals, rocks, and fossils, as well as aspects of rivers, oceans and atmosphere, the geologist interprets earth history, the evolution of life, the movement and development of continents, and the changing aspects of the ocean basins. The study of earth materials takes place in the field and in the laboratory, and depends upon a rock hammer as well as sophisticated analytical equipment. Within the broad field of geology, professionals specialize in a variety of subjects including mineral resources, groundwater, sedimentary, igneous and metamorphic rocks, volcanoes, geophysics, geochemistry, fossils and many others. This specialization leads to employment by private industry, federal, state, and local governmental agencies, consulting firms, and by secondary schools needing earth science teachers. Many of our graduates work in the fields of exploration and development for minerals and fuels. Others work in a variety of fields related to construction, site selection, water supply, environmental remediation and planning. Jobs in geology are available at the B.A., M.S., and Ph.D. level. However, the more creative the position, the higher level of education needed, and a master's degree is advisable for flexibility in professional employment.

The Department of Geology offers B.A., M.S., and Ph.D. degrees; also available is a bachelor degree with a teaching major in earth sciences. All degree programs in the department involve field work and a combination of applied and theoretical approaches requiring sound general background in other sciences.

High School Preparation: In addition to the general requirements for University admission, recommended high school preparation includes as much mathematics and science as possible.

Special Degree Requirements

Refer to graduation requirements listed previously in the catalog. See index.

There are three emphases for the bachelor degree in geology. Both the emphasis in geology and the emphasis in environmental geology prepare the student for graduate work in geology and for practice in the geologic profession. The emphasis in earth science education is for students seeking certification to teach.

Emphasis in Geology

The following courses are required: Geology 100N, 130, 202, 305, 306, 330, 429. One course also must be selected from each of the following three categories: (1) Geology 378, 431, 480; (2) Geology 437, 430; (3) Geology 310, 420, 432, and 451. A minimum grade of "C" is required in prerequisites for these courses. Admission to certain geology courses (see course descriptions) will be limited to students having a grade point average, overall and in geology courses, of 2.25 or better. To assure satisfactory completion of this emphasis, geology majors should achieve the 2.25 grade point average specified above by the time they become juniors.

Also required are 41 credits in mathematics and allied sciences. Unless a different program is approved in writing by a geology undergraduate advisor, a program will consist of the following:

Chemistry 161N, 162N (lectures) 164N, 165N (labs)
Computer Science 101
Math 152 and 153 or 150 and 158
Physics 221N and 222N or 121N and 122N
Other (May include physics, biology, mathematics, astronomy, microbiology, computer science)

Most graduate schools and professional employers require college preparation in these subjects. Science courses designed for education majors may not be counted toward the departmental science requirements. Communication skills are important to the geologist and the department recommends that students fulfill their general education requirements in expressive arts by including Comm 111A.

Emphasis in Environmental Geology

The following courses in Geology are required: 100N, 105N, 130, 301, 226, 431, 480, 499 plus Geology electives at the 300-level or above for a total of 33 credits. Also required are 41 credits in mathematics and allied sciences. Unless a different program is approved in writing by a geology undergraduate advisor, a program will consist of the following:

Chemistry 161N, 162N (lectures); 164N, 165N (labs)
Computer Science 101
Math 152 and 153 or 150 and 158
Physics 221N and 222N or 121N and 122N 10
Other (Biol 105N, CS 203, 204, 344, 365; Math 158, 251, 311, 312, 341; Chem 261, 262, 263, 264, 344, 342, 348, 370, 371, 452, 476; Micb 306) 10

The communication skills requirement is the same as for the emphasis in geology. Pass/Not Pass grades are generally given for work in Geology 590 and above. Geology majors may, with the consent of the instructor, take geology courses on a pass/not pass basis, provided the course is not required for the major. Required allied sciences and communication skills courses must be taken for regular grade.

Summary of Requirements:
  1. Geology courses
  2. Allied science and mathematics
  3. Communication skills....................
  4. Electives and General Education to total 130 credits

Certain departmental requirements can be waived for students who at the end of any complete year have a B average in all college courses previously taken while pursuing a standard geology curriculum. A special geology curriculum may be devised for these students in consultation with their advisor. This will, for example, allow for a curriculum planned for special areas of interest, such as geochemistry, geophysics, or paleontology. This flexibility is applicable at the end of the freshman year and to transfer students, and can be revoked if the grade average falls below B.

Emphasis in Earth Science Education

Major Teaching Field of Earth Science: A student must complete Geol 100N, 105N, 130, 301, 226, 310, 330, 3 additional credits from any geology course numbered 100 or above, and 12 credits from any geology courses numbered 300 or above. Also required are Geog 330N, Astr 131N-132N, Math 121, 344, CS 101, Chem 485, and C&I 426. Biol 121N-122N and Chem 151N and Phys 121N-122N must be completed.

For endorsement to teach earth science, a student also must gain admission to Teacher Education and Student Teaching and meet the requirements for certification as a secondary teacher (see the School of Education section of this catalog).

The demand in most Montana high school for teaching in this field may be limited, and students should complete the requirements for the required second teaching endorsement (major or minor).
