MANTLE  PETROLOGY

The research centered around mantle petrology concentrates upon the petrologic evolution of different mantle and lower crustal domains.  Specific research projects includes the geochemical history of mantle and lower crustal xenoliths, megacryst petrogenesis and mantle metasomatism.
