anatectic migmatites

U-Pb dating of anatectic migmatites at Gaozhou in the Yunkai Block, western Guangdong, China;

粤西云开地块内高州地区深熔混合岩的锆石U-Pb年龄

Petrological and geochemical studies demonstrate that the granitoids occured in Foping areacan be divided into two genetic types:The anamigmatization type and continental crust remeltingtype,They have distinctive field geological and REE geochemical characteristics,and reflect the tec-tonic heat events under different evolution stages of the orogenic belt.

通过岩石学和地球化学研究，认为佛坪地区花岗岩类可分为两种不同的成因类型：深熔混合岩化型和陆壳重熔型。
