Welcome to the home page of the Igneous and Metamorphic Petrology Group in the Graduate School of Life and Environmental Sciences (Earth Evolution Sciences), University of Tsukuba (Japan). Our research interests are many and varied, but they are all field-based studies of topics ranging from metamorphism of high-grade rocks in Gondwana fragments to geochemistry of various igneous rocks from all over the world.
