U-Pb Dating of Anatectic Migmatites in the Yunkai Block, Gaozhou,Western Guangdong
摘要
Abstract
The regional migmatites in the Yunkai Block were formed under low-pressure metamorphism. The majority of their protolith are biotite-rich peraluminous gneisses. Detailed field observations, and studies of petrology, spatial distribution of minerals and geochemistry suggest that the leucosomes were derived from anatexis. The single grain zircon U-Pb dating data indicate that a pulse of migmatization occurred at 394~ 449 Ma and may have resulted from the large-scale Caledonian magmatism in the Yunkai Block.关键词
