| 英文摘要 | Exsolution textures were observed in clinopyroxenes in mafic granulites from the Grove Mountains, East Antarctica. The first generation of exsolution occurs only in subcalcic augite megacrysts, in which coarse orthopyroxene lamellae exsolved parallel to the (100) plane. Electron microprobe reintegration of such augites yields a pre-metamorphic igneous temperature of ca. 970degreesC. The second generation of exsolution develops in both igneous and metamorphic clinopyroxenes. In metamorphic clinopyroxenes, two sets of very narrow pigeonite lamellae, subsequently inverted to orthopyroxene, exsolved parallel to (100) and (001) planes, respectively with 0degrees and 113degrees deviation to c-axis of the host. A peak metamorphic temperature of ca. 850degreesC was obtained from the reintegrated compositions of exsolved clinopyroxene, and an exsolution temperature of 740-770degreesC from the orientations of exsolved lamellae. |
