摘要
1.Objectives As one of three major tectonic blocks of China,the South China Block has undergone multiple periods of tectonic-magmatic-metamorphic events.Among these events,the Caledonian orogeny results in the formation of NE-trending Wuyi−Yunkai orogen in South China.This orogen shows complex characteristics,including widespread angular unconformity between Ordovician and Devonian strata,pre-Devonian intense deformation and metamorphism(amphibolite to granulite facies).
