The Department of Geology offers programs lead- ing to the Master of Science degree (thesis) and the Master of Science in Teaching (nonthesis). Areas of specialization include engineering geology, environ- mental geology, geochemistry, geomorphology, geophysics, industrial mineralogy, marine geology, mineralogy-petrology, paleontology-stratigraphy, pe- troleum geology, sedimentary petrology, and sedimentology. For admission to graduate status in the Department of Geology, a student must have a baccalaureate de- gree with a major in geology or a related field. A course in field methods or a summer field course is re- quired. Deficiencies in undergraduate work in geo- logy can be corrected by completing the under- graduate courses without credit while enrolled as a graduate student. Applicants for a master's program in geology must have completed courses in the areas of physical geology, historical geology, crystallography-mineralogy, igneous and metamorphic petrology, optical mineralogy, sedimen- tary geology, invertebrate paleontology, and struc- tural geology. In addition, students must have com- pleted courses in supportive sciences, such as mathe- matics, physics, chemistry, statistics, and biology. Thirty-three semester hours will be required for the Master of Science in geology, of which at least seven courses, totaling at least 21 hours, must be organized geology courses (excluding research, teaching, special projects, etc.). A maximum of six hours of thesis re- search credit will be allowed. The remaining credits can be either in additional geology courses (excluding GLY 6905, 6910 and 6940), approved electives, or in a declared minor in another field. Each student must take the Graduate Record Exami- nation Advanced Test in Geology either prior to ad- mission to the Graduate School or as soon as possible after acceptance. The score on this examination must be reported to the Department of Geology. After one semester of residence, each graduate student must successfully pass a comprehensive oral examination covering the basics of geology. An acceptable thesis must also be completed.
