解釋

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。 -
Greenschist facies, low green schist facies and brittle shear deformation facies. the attitude of different structural element of the yagan mcc are keeping coordination. analysis of kinematics demonstrates the sse - directed shearing - off of the hanging wall relative to the footwall along the penetrative mylonitic lineation
其變形相由變質核中心到上盤巖系（由深至淺）依次為高角閃巖相? ?綠片巖相? ?低綠片巖相? ?脆性剪切變形相，顯示亞干核雜巖由中心向邊部變形層次遞減的特點。 -
These clearly demonstrate that the mcc formatted by long - history processes with poly stages. by strain analysis, the fabrics deformational style of the yagan mcc are mainly shearing type, the yagan mcc is mainly a thinning shear zone with volume loss, which varies from - 31 % ~ - 58 %. analysis of kinematic vorticity ( wk varies from 0. 453 - 0. 809 ) shows shear type of the shear zone is neither pure shear nor simple shear but general shear
應變分析表明，亞干變質核雜巖主期變形為以剪切變形為主（羅德系數u在0 . 08 ? 0 . 32間）壓扁次之（ u0 . 89 ）的變形類型，核雜巖區為一有體積損失的減薄型剪切帶，體積損失率達- 31 ? - 58 。
