英文摘要	The southern Yiwulushan metamorphic core complex in Zhangjiabao area represents two suits of granitic rocks: Archean granitic gneiss which contains abundant biotite plagioclase gneiss enclaves; late intrusive K-feldspar granitic gneiss and granitic dykes. Detailed macroscopic and microscopic structural investigations indicate two ductile deformation events which developed in these granitic rocks: Late Jurassic ductile shear zone under high deformation temperature of about 550 similar to 600 degrees C, and Early Cretaceous ductile shearing under low deformation temperature about 400 similar to 450 degrees C. Early deformation event was mainly formed under the condition of upper greenschist to lower amphibolite facies, which in simple dominated shearing with L = S and LS tectonites with dextral shearing characteristics. Late ductile deformation event was formed under greenschist facies metamorphism, consisting mainly of equally simple and pure shearing with L = S tectonites with sinistral shearing features. The estimation of rock rheological parameters from dynamically recrystallized grain sizes of quartz indicates that early high temperature shear zone have a lower paleo-stress with higher strain rates, and opposite features exist in late lower temperature shearing. Late Jurassic extensional deformation might be related to Izanagi Plate and Farallon Plate NNW obliquely subducting under the eastern margin of Eurasia plate. The late deformation event, occurred in Early Cretaceous, which is related to the lithospheric thinning and extension of the North China Craton triggered by roll-back of the Izanagi Plate beneath the eastern North China Craton.
