Structural Characteristics and Plate Boundary Properties of the Kangguertage Fault Zone in Jueluotage Orogenic Belt, Eastern Tianshan

Served as an important part of Central Asian orogenic belt, the Jueluotage area is the key collision belt between Tarim plate and Paleo-Asian Ocean. However, its tectonic attribution has been controversial. The Kangguertage fault zone is the boundary fault of the Jueluotageorogenic belt, the study of structure characteristics has important enlightenment function on the tectonic evolution about this area. In this paper, the Kangguertage fault zone has been studied ongeological characteristics, volcanic sediment and evolution. The results show that the Kangguertage zone is a ductile shear belt in deep leveland is characterized by apparent strike-slip; The carboniferous volcanic rocks in this area show typical characteristics of trench-arc-basin volcano-sedimentary formations; The area between Kangguertage and Aqqikkuduk fault zones is the collision suture belt of Junggar and Tarim Plates; From Late Carboniferous to Early Permian, the asymmetric bisubduction took place southward and northward in Kangguer Ocean respectively, causing the formation of Kangguertage-Aqqikkuduk suture zone, with the Kangguertage fault zone served as a northern border of this suture zone.
