 The Department of Geology offers programs leading to
the Master of Science degree (thesis), the Master of
Science in Teaching (nonthesis), and the Doctor of Phi-
losophy degrees. Areas of specialization include eco-
nomic geology, engineering geology, environmental
geology, geochemistry, geomorphology, geophysics,
hydrogeology, industrial mineralogy, marine geology,
mineralogy, paleontology, petroleum geology, petrology,
sedimentary petrology, 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 undergradu-
ate 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,
historical geology, crystallography-mineralogy, igneous
and metamorphic petrology, optical mineralogy, sedi-
mentary geology, invertebrate paleontology, and struc-
tural geology. In addition, students must have completed
courses in supportive sciences, such as mathematics,
physics, chemistry, statistics, and biology.
 A minimum of 30 semester hours of graduate level
courses will be required for theMaster of Science in
geology. At least 24 .hours must be in organized graduate
level geology courses (excluding research, teaching,
special 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 doc-
toral program. A separate and new application for admis-
sion to the doctoral program is required.
 Of the 90 semester hours required for the Ph.D., 45
must be in formal, organized graduate-level classwork
(excluding individual work, supervised research and
teaching, advanced research, dissertation, special proj-
ects, etc.). Remaining credits will be in GLY 7979, 7980,
additional geology courses, or a declared minor in an-
other 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 least 24 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 student must take the Graduate Record Examina-
tion (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 recommen-
dation 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 copies may be obtained by con-
tacting the department directly.
