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
亚干变质核杂岩由下盘结晶岩系变质核、拆离带和上盘岩系构成，其中，变质核由四个单位及许多花岗岩体(脉)组成，可进一步分为中深和中浅变质两个构造单位(岩片) ，之间发育次级韧性拆离带(花岗质糜棱岩带) ，加上上盘总体构成“三层两带”的结构特点。
