Biographical Information
Jade Star Lackey offers courses in mineralogy, igneous & metamorphic petrology, geochemistry, and introductory geology. His research incorporates a breadth of petrologic and geochemical tools to investigate igneous and metamorphic rocks and relate their petrogenesis to the growth and evolution of continental crust. Jade Star has several active research projects nearby in the Sierra Nevada, but also conducts research on peraluminous granites in Maine and Nova Scotia. Additionally he and students are studying pyrometamorphic deposits in the Powder River basin of Wyoming. Current research interests include: (1) Deciphering the magma system evolution in convergent margin batholiths; (2) monitoring fluid fluxes from such batholiths by isotopic studies of marble roof pendants; (3) applying oxygen isotope analysis of garnet and zircon to parse apart contamination events in peraluminous magmas; (4) resolving terrane cooling histories by oxygen isotope analysis of titanite; and (5) evaluating trace element mobility in natural coal fire deposits.
