Dr. Lange, a Professor of Geology at the University of Montana, specializes in the study of metallic mineral deposits. He has researched and published primarily on the geology, geochemistry and genesis of
Reseach has been funded in part by more than $600,000 in grants and contracts. Geochemical aspects including fluid inclusion-derived data and stable isotopic studies (S, C, and O) form an integral part of Dr. Lange's research.

Dr. Lange wass involved in teaching classes and laboratories at all levels of the Geology Department's undergradate and graduate program. Introductory Geology and Volcanoes and Earthquakes were taught in addition to the Minerals and Rocks class required of undergraduate majors. At the graduate level Dr. Lange taught Applications of Isotope Systematics to Geologic Problems, Environmental and Descriptive Aspects of Ore Deposits, and special topics such as Precious Metal Deposits and Fluid Inclusion Studies, when requested by students. Dr. Lange has directed undergraduate and approximately 40 M.S. and Ph.D. theses.
