Geometry and Kinematics Characteristic of Cratonic Strike-Slip Fault in Tarim Basin: Case Study of Yueman20 Fault

Summary The study of cratonic strike-slip fault is relatively weak. This paper takes Yueman20 fault as an example to discuss the geometry and kinematics characteristics of cratonic strike-slip fault. The Yueman20 fault spreads NW in the north, SN in the middle and NE in the south with stratified deformation in profile, which shows as vertical fault or flower structure in Cambrian –Ordovician and negative flower structure in Silurian- Carboniferous. The fault is dextral strike-slip fault with the maximum horizontal displacement of 1.6 km. The activity intensity is weak in the south, while strong in the middle and north. Yueman20 fault has obvious segmentation, and it can be divided into linear segment, compressional segment and transtensional segment alternately along the fault.
