| 英文摘要 | The Paleoproterozoic HP mafic granulite and cab-silicate were found from Laixi, Jiaobei terrane, consisting of almandine dominated garnet-augite-ferrohypersthene and grossular-zoisite-prehnite-albite respectively. Mineralogical and petrological studies show that the calc-silicate formed after the HP mafic granulite by processes combined retrogressive metamorphism with Ca alteration. The HP mafic granulites records four stage geological processes, including pre-granulite facies, peak granulite facies, retrogressive combined with Ca alteration and complete Ca alteration processes with mineral assemblages as Cpx + Pl + Qtz (M-1), Grt + Cpx + Rt + Qtz (M-2), Cpx + Pl + Opx + Ilm + Mgt + Ep (M-3) and Grs + Zo + Prh + Ab + Cal (M-4). The HP mafic granulite is rich in LIL elements Ba, Rb, K, Rh, Th and depleted in HFS elements Nb, Zr, Ti and Y, having LREE rich right-inclined REE pattern and showing island-arc basaltic characteristics. Further studies by using discrimination diagrams, the HP mafic granulite presents island-arc tholeiitic characteristics, probably formed in the back-arc extension tectonic setting. After formation of the mafic rock, it experienced granulitic facies metamorphism during collisional convergence of the Jiao-Liao-Ji orogenic belt and afterwards experienced retrogressive and Ca alteration processes during the lift of the belt. |
