摘要: Paleozoic crust–mantle interaction and geodynamic setting of the South China Block have remained largely elusive due to the scarcity of mafic rock suites. Here we report data from a suite of mafic rocks including norite, mafic granulite, garnet-bearing amphibolite, biotite-bearing amphibolite, and amphibolite from the Chencai region in the northeastern Cathaysia Block of South China, that mostly record amphibolite to granulite facies metamorphism. U–Pb dating of zircons from the mafic granulite and biotite-bearing amphibolite show broadly …
