Abstract: | The syncollisional mafic-ultramafic intrusions in the North Dabie terrane are characterized by enriched LREE, Rb, Ba, and depletion of high field strength elements, such as Nb, Zr, Ti. The high Ti/& and Ti/Y ratios of their parent magma suggest that crust contamination of magma is not important to the above trace elements characters. They mainly reflect the features of their mantle source which has been modified by metasomatism in subduction environment. |
