| 英文摘要 | Omphacite and garnet coronas around amphibole occur in amphibolites in the Hong'an area, western Dabie Mountains, China. These amphibolites consist of an epidote-amphibolite facies assemblage of amphibole, garnet, albite, clinozoisite, paragonite, ilmenite and quartz, which is incompletely overprinted by an eclogite facies assemblage of garnet, omphacite and rutile. Coronas around amphibole can be divided into three types: an omphacite corona; a garnet-omphacite-rutile corona; and, a garnet-omphacite corona with less rutile. Chemographic analysis for local reaction domains in combination with petrographical observations show that reactions Amp + Ab + Pg = Omp +Czo + Qtz + H2O, and Amp + Ab = Omp +/- Czo + Qtz + H2O may lead to the development of omphacite coronas. The garnet-omphacite-rutile corona was formed from the reaction Amp + Ab + Czo + Ilm +/- Qtz = Omp + Grt + Rt + H2O. In garnet-omphacite coronas, the garnet corona grew during an early stage of epidote amphibolite facies metamorphism, whereas omphacite probably formed by the reactions forming the omphacite corona during the eclogite facies stage. It is estimated that these reactions occurred at 0.8-1.4 GPa and 480-610degreesC using the garnet-clinopyroxene thermometer and omphacite barometer in the presence of albite. |
