| 英文摘要 | As one of the most significant regional faults in the Central Asian Orogenic Belt, the Erqis fault was hotly debated on its kinematics. Three representative models have been proposed: strike-slip fault, thrust fault or transpressional fault. Our work in southern margin of the Chinese Altay indicates that the Erqis fault and its subordinate faults compose the Erqis fault zone, which is a ductile high strain zone with 20 similar to 40km in width and 400km in length, and experienced variable deformation. All the southern margin of the Chinese Allay was influenced by ductile shearing. The Erqis fault zone experienced two tectonic events: sinistral strike-slip and dextral strike-slip shearing. Combining our work with the existing studies of the ductile-shear-zone-type gold deposits, syntectonic deformed plutons and Ar-40/Ar-39 ages in metamorphic rocks, it is inferred that the sinistral strike-slip event occurred in the Early Permian (283 similar to 275Ma). Thereafter, probably in the Late Permian (260 similar to 245Ma), the Erqis fault zone was partially modified by a dextral strike-slip event which was much weaker than the former. Furthermore, based on the establishment of the kinematic model of the Erqis fault zone, important lines of evidence have been brought forward to discussing the post-orogenic adjustment during the Permian in North Xinjiang and the Central Asian Orogenic Belt. |
