| 英文摘要 | Seven stages of mineral assemblage were recognized in the Zhimafang orogenic garnet lherzolite from the Sulu ultrahigh-pressure (UHP) metamorphic terrane of eastern China, which suggest that it experienced progressive mantle wedge convection during subduction of previous oceanic and subsequent continental slabs. M, is recorded by inclusions of high-Mg olivine, high-Mg-Al-Cr-Ca orthopyroxene and high-Mg clinopyroxene in the high Ca-CF Cores of the garnet porphyroclasts, suggesting that the Zhimafang peridotite was probably a garnet lherzolite originated from a deep and hot mantle wedge above the previously subducted oceanic slab. M(2) is represented by inclusions of high-Mg-Al chromite, high-Mg olivine and high-Mg orthopyroxene in the low-Cr mantles of the garnet porphyroclasts and core of the matrix garnet, suggesting that the rock was convected to shallow and hot mantle wedge, and was transformed to refractory spinel harzburgite or spinel dunite due to high degree of decompressional partial melting. M(3) is manifested by the origin of metasomatic clinopyroxene and orthopyroxene porphyroblasts with inclusions of high-Fe chromite, tremolitic or edenitic amphibole, phlogopite. barite and pyrite, indicating that the rock was convected to shallow, cold and wet corner of the mantle wedge, and was transformed to a fertile amphibole-bearing spinel Ilherzolite during continental subduction. The lherzolites was subsequently transformed to high-pressure (HP) amphibole-bearing garnet lherzolite M) and UHP garnet lherzolite (Ms), indicating its convection to deep mantle wedge. Finally. the UHP garnet-lherzolite exhumed to the Earth's surface, together with the UHP terrane, and Subsequently retrograded to amphibole-bearing garnet lherzolite (W and chlorite-amphibole-bearing spinel lherzolite (W. Detailed analyses of reaction textures and mineral compositions revealed several stages of metasomatism related to oceanic and continental subduction and exhumation. (C) 2008 Elsevier B.V.
