Texas Tech University

Minerology and Petrology


Faculty and students in the department conduct research in the fields of:

  • Igneous and Metamorphic Petrology
  • Mineralogy and Crystallography
  • Clay Mineralogy

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.



Dr. Callum Hetherington, mineralogy, geochemistry, and micro-analytical study of igneous and metamorphic rocks.

Dr. Branimir Segvic, clay mineralogy and low-temperature geochemistry.

Dr. Aaron Yoshinobu, microstructural evolution of the lithosphere, structural petrology of arc & ophiolite/oceanic spreading centers.
