摘　　要：Platinum-group elements （PGE） are mainly concentrated in some specific minerals known as PGMs, which commonly occur in podifbrm chromites of ophiolites. In-situ PGM assemblages in chromites can provide valuable information on the physico-chemical nature of the parental melt（s） from which chromitite crystallized （Melcher et al., 1997）, and used as a significant petrogenetic indicator.Platinum-group elements （PGE） are mainly concentrated in some specific minerals known as PGMs, which commonly occur in podifbrm chromites of ophiolites.
