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 and California, but also conducts research on granites in Maine and Nova Scotia. 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 skarn deposits; (3) applying oxygen isotope analysis of garnet and zircon to parse apart contamination events in peraluminous magmas; (4) evaluating the connections between volcanic and plutonic magma systems in convergent margin batholiths; (5) applying stable isotope (O/D-H) analyses of hydrothermal cements to study the tempo and mode of shallow geothermal system evolution in Long Valley caldera.
