Research in Mineralogy and Petrology


Faculty and students in the department conduct research in the fields of igneous and metamorphic petrology, mineralogy and crystallography. Much of the research is field-oriented with current projects working in the Klamath Mountains (California & Oregon), the Ruby Mountains (Nevada), the Caledonides of central Norway, the Seiland and Tysfjord regions of north Norway, various ophiolites and oceanic spreading centers, as well as west Texas and eastern New Mexico.

The Min-Pet group also holds various informal discussions, seminars, and group meetings.

Faculty members in the Mineralogy and Petrology group include:

Dr. Cal Barnes, Professor. Petrology & geochemistry of igneous & metamorphic rocks. Email:

Dr. Melanie Barnes, Application of LA-ICP-MS to Earth Materials. Email:

Dr. Callum Hetherington, Assistant Professor. Mineralogy, geochemistry, and micro-analytical study of igneous & metamorphic rocks. Email:
