The Gangdese belt in southern Tibet preserves a series of Miocene post-collision environmental economic deposits which excert a strong focus on research of economic geologists. Moreover, there are a number of porphyry copper deposits that related to intermediate-felsic intrusions. With the in-depth study, abundant Miocene mafic microgranular enclaves (MMEs) in felsic host rocks are founded (Yang et.al., 2008). From previous study about MMEs in Gangdese belt in southern Tibet, Most scientist (Mo et.al., 2008; Zheng et.al., 2013) argue that it derived from magma mixing between mantle-derived mafic magma and crust-derived felsic magma in Gangdese belt. In addition, the MMEs experience a process of exchange of mass-energy and materials between mantle-derived mafic end-member and crust-derived felsic end-member.
