The podiform chromitites in the Luobusa ophiolite,Southern Tibet,have received much attention because of the presence of ultrahigh-pressure minerals,such as micro-diamonds(Bai et al.,1993; Yang et al.,2007; Xu et al.,2009),coesite(Yang et al.,2007)and highly reduced metal phases(Bai et al.,2000; Robinson et al.,2004).The occurrence of diamonds,stable over 150 km deep in the mantle,suggests that the podiform chromitite in the Luobusa have a deep mantle origin(Yang et al.,2007).
