Research and Teaching Interests

Dr. Parker's interest in volcanology and igneous petrology originated during visits to Big Bend National Park and the Davis Mountains of West Texas while he was a teenager. He has followed this interest for more than twenty years, chiefly focusing his research upon major and trace element geochemistry of silicic systems. Dr. Parker believes that integrated studies of volcanic systems, involving both field and laboratory analysis, provide the best approach to solution of problems associated with these systems. Consequently, mapping of volcanic terranes and volcanologic analysis are as important as chemical and isotopic studies in Baylor student projects.

Long-term areas of research at Baylor include the evolution and eruptive behaviors of silicic alkalic systems, origin of extensive silicic lavas and rheomorphic tuffs, and origin of dacite and rhyolite in calcalkalic suites. Specific problems that have been investigated include the origin of pantellerite from Pantelleria, Italy and the Davis Mountains, West Texas, the origin of rhyolite in the Conejos Formation of the San Juan Volcanic Field, Colorado, and the petrogenesis of Oregon Coastal Basalts. Current projects include the study of South Sister Volcano in the central Oregon Cascades, petrogeneisis of metaluminous rhyolite in the Davis Mountains of West Texas,and comendite from Big Bend National Park, and the puzzling presence of subduction trace element characteristics in rocks of the Rio Grande Rift.

Dr. Parker teaches advanced courses in Igneous Petrology, Analytical Geochemistry, and Volcanology, as well as undergraduate Petrology and introductory geology classes.
