The Department of Geology offers programs leading to the Master of Science (thesis), the Master of Science in Teaching (nonthesis), and the Doctor of Philosophy de- grees. Areas of specialization include economic geology, engineering geology, environmental geology, geochemis- try, geomorphology, geophysics, hydrogeology, industrial mineralogy, isotope geology, marine geology, mineralogy, paleomagnetism, paleontology, petrology, sedimentary pe- trology, sedimentology, and stratigraphy. For admission to graduate status in the Department of Geology, a student must have a baccalaureate degree with a major in geology or a related field. A summer field course is required. Deficiencies in undergraduate work in geology can be corrected by completing the undergraduate courses without credit while enrolled as a graduate student. Applicants for any of the programs in geology must have completed courses in the areas of physical geology, histori- cal geology, crystallography-mineralogy, igneous and meta- morphic petrology, optical mineralogy, sedimentary geol- ogy, invertebrate paleontology, and structural geology. In addition, students must have completed courses in support- ive sciences, such as mathematics, physics, chemistry, statistics, and biology. A minimum of 30 semester hours of graduate level courses will be required for the Master of Science in geology. At least 24 hours must be in organized graduate level geology courses (excluding research, teaching, spe- cial projects, etc.). Six hours of thesis research credit are required. All master's degrees are terminal and do not entitle the recipient to automatic admission to the doctoral program. A separate and new application for admission to the doctoral program is required. Of the 90 semester hours required forthe Ph.D., 45 must be in formal, organized graduate-level classwork (exclud- ing individual work, supervised research and teaching, advanced research, dissertation, special projects, etc.). Remaining credits will be in GLY 7979, 7980, additional geology courses, or a declared minor in another field. For the Master of Science in Teaching degree, at least 36 hours are required. Six of these hours must be in GLY 6943 and at least24 must be in organized graduate-level geology courses. The remaining six hours must be in approved electives. Passage of a final oral examination is required of all candidates. Each applicant (M.S. and Ph.D.) must take the Graduate Record Examination (General and Advanced). Applicants for the Ph.D. or M.S. degree program who are from a discipline outside geology must take the Advanced GRE in their particular field. The scores of these examinations must be reported to the Department of Geology. Three letters of recommendation are also required for admission to the doctoral program. The Department of Geology has prepared a document of policies, procedures, and requirements pertaining to its graduate programs and a brochure describing current fac- ulty and their research interests. Copies may be obtained by contacting the Department directly. BOT 5115-Paleobotany(3) Prereq: upper-level course in botany or geology or permission of instructor.
