Abstract Mass transfer between crust and mantle at continental margins is a crucial process in shaping heterogeneity material cycling deep Earth. usually archived by the slab-derived and/or asthenosphere-derived component, which metasomatize cratonic wedge. Clarifying origin temporal sequences of these records fundamental aim yet poorly resolved. Comprehensive petrography, whole-rock mineral co...

Introduction: Chondrules are believed to have formed by a brief but intense heating and melting event in the early solar system. Melting erased most mineralogical information about chondrules’ precursors. A sub-group of chondrules is rich in alkali elements and was classified as Naand Al-rich chondrules [1]. We describe two Na-rich chondrules and discuss their phase relations in order to disent...
