Detail mapping shows that the yagan mcc consists of crystallized metamorphic core ( low plate ), detachment zone and upper plate. the metamorphic core consists of can be further subdivided into two level parts low - level high metamorphic and upper - level shallow metamorphic structural slice and between them there exists a ductile shear zone. thus the whole texture of the mcc is characterized by " three layers and tow zones " this reveals a process of extensional uplift of poly - level slices by poly ductile shear zones, a characteristics of poly - level extensional structural systems. the deformational environments change vertically in a sequence of high amphibolite facies
亞干變質核雜巖由下盤結晶巖系變質核、拆離帶和上盤巖系構成,其中,變質核由四個單位及許多花崗巖體(脈)組成,可進一步分為中深和中淺變質兩個構造單位(巖片) ,之間發育次級韌性拆離帶(花崗質糜棱巖帶) ,加上上盤總體構成「三層兩帶」的結構特點。
