| 英文摘要 | Ningshan Fault is a large-scale WE-trending fault in Qinling Orogen. This research indicates that the left-lateral shear zone exhibit abundant ductile shear fabrics of earlier stage which were superimposed by a late brittle deformation. Ar-40-Ar-39 ages on syn-deformational and syn-metamorphic minerals from the Ningshan Fault confirmed that the early ductile deformation occurred during 169 similar to 162Ma and was formed in the intracontinental deformation in the period of post-collision of Qinling Orogen. Existing of this left-lateral shear zone indicates that the tectonic belt of South Qinling Orogen may be subdivided into two different unites before Middle-Late Jurassic. Some metamorphic rocks of old basement crops out on the NW side of the Ningshan Fault and were intruded by many Mesozoic granitic plutons; on the SE side of the fault, however, dominant Meso- and Neo-Proterozoic low-grade metamorphic volcanic rocks and metasediment was intruded by basic and alkalic dykes of Neo-Proterozoic to Early Paleozoic. It has been confirmed that large-scale left-lateral shear movement occurred in the western and northern margins of Yangtze block in the Late-Middle Jurassic to the Early Cenozoic, which may be connected with the clock-wised rotation of the block in that time. |
