The Department of Geological Sciences offers programs leading to the M.S. and Ph.D. degrees in geological sciences. A broad background is offered in most major areas of geoscience, with particular emphasis on hydrology, coastal processes, isotope geochemistry, geochronology, seismology, volcanology, igneous petrology, marine geology, low-temperature geochemistry, paleoclimatology, paleoceanography, paleontology, paleoecology, sequence stratigraphy, structural geology, earth surface processes, and tectonics.

Admission and General Degree Requirements

Students admitted to pursue a graduate degree in the Department of Geological Sciences normally are expected to have an undergraduate degree in traditional geology, geochemistry, geophysics, biology, chemistry, mathematics, physics, or other related interdisciplinary fields. All applicants must take the Graduate Record Examination (GRE). All foreign students whose native language is not English also must take the Test of English as a Foreign Language (TOEFL) examination.

Course requirements for incoming students will be determined by individual graduate committees, often in consultation with the director of graduate studies. Specific requirements are varied to meet the needs and career objectives of the individual.

Master of Science

Requirements for the Master of Science degree are 30 semester hours (including a minimum of three hours, but no more than six hours of GEOL 993), a thesis, and a final oral examination in defense of the thesis.

Doctor of Philosophy

Many students have completed a master's degree before being admitted to the doctoral program, but some students enter the Ph.D. program having completed only an undergraduate degree. Students admitted to the M.S. program who elect pursue a Ph.D. instead may be permitted to bypass the master's degree after one semester of residence upon demonstration of superior scholastic performance and research potential. Recommendation by the student's graduate committee and approval by the geological sciences faculty is required in this case.

Admission to the Ph.D. program after completing the M.S. degree in the Department of Geological Sciences requires faculty approval.

Requirements for the Ph.D. degree are a minimum of 48 semester hours of graduate credit (which may include 30 hours from the M.S. degree) plus a minimum of six hours and preferably no more than 12 hours of GEOL 994, a written comprehensive examination and an oral comprehensive examination, a dissertation, and a final oral examination in defense of the dissertation.

Facilities and Research Interests

The Department of Geological Sciences occupies the 50,000 square feet of floor space in Elisha Mitchell Hall. Research equipment and facilities include two thermal ionization mass spectrometers with associated Class 100 clean labs; high-resolution laser ablation ICPMS; quadrupole ICPMS; a sediment analysis laboratory including refrigerated core storage, an X-ray fluorescence core scanner and a laser-size particle analyzer; X-ray fluorescence spectrometer; X-ray diffractometer; field-emission electron microprobe (at Fayetteville State University; remotely operable); scanning electron microscope with X-ray analysis and cathodoluminescence; counting laboratory (alpha-, beta-, and gamma-emitting radionuclides); experimental petrology laboratory; gas chromatograph- isotope ratio mass spectrometer (in Marine Sciences); chirp sonar and side-scan sonar imaging systems; seismic reflection system; microsampling system with epifluorescence capabilities. The Department excels in advanced computational methods and numerous high-end workstation facilities are available, including GPU enhanced parallel processors. Campus-wide supercomputer clusters are available through the North Carolina Supercomputing Center.

Financial Aid

Approximately 11 teaching assistantships with stipends of $14,700–$15,700 per academic year (2013–2014 stipends) are available to graduate students. In addition, all graduate students are eligible to apply for departmental summer fellowships, research funds, and conference funds ($1000 - $7,000 per award in 2013–2014) from a departmental endowment.

The department nominates three students to be considered by The Graduate School for nonservice fellowships; no additional application is necessary. Faculty research grants support some research assistantships. Out-of-state students are recommended for remission of out-of-state tuition costs; all students are recommended for an in-state tuition award. Most students are eligible for both, and therefore are responsible only for the payment of student fees.
