摘要
Jiaobei terrane contains low to high grade Paleoproterozoic metamorphosed sedimentary sequence deposited under littoral to neritic environments, belonging to part of the Jiao-Liao-Ji belt of the eastern block in the North China Craton. This study focuses on the formation of calc-silicate that is closely associated with HP mafic granulite. The results show that the calc-silicate develops on the late stage of continent-continent collision during the exhumation process of the HP granulite, combined with Ca metasomatism at the same time. Establishment of the genetic relationship of calc-silicate and the mafic garnet granulite present the importance of petrological paragenetic association during the exhumation of collisional metamorphic terrane.
