The Songshugou ultramafic pluton of the Shangdan fault is the largest ultramafic body in the East Qinling Orogen and assumes the emplacement contract with the Qinling complex. The pluton is composed mainly of fine-grained as well as medium-and coarse-grained dunite and plagioclase-pyroxene peridotite.This paper presents new data on the inclusions and trace element concentrations of zircons from garnet amphibolites that occur in a metamorphic contact zone. Studies indicate that the ultramafic intrusion and adjacent amphibolites experienced different tectonic events, and the ultramafic pluton was emplaced in amphibolites formed before. Geochemical data suggest that amphibolites have characteristics of MORB and IAT and likely belong to the Qinling Group.
