东天山觉罗塔格造山带康古尔塔格断裂带构造特征及边界属性研究

东天山觉罗塔格造山带是塔里木板块和古亚洲洋碰撞对接的关键部位，为中亚造山带的重要组成部分，而其大地构造属性一直存在着争议。康古尔塔格断裂带作为觉罗塔格造山带的边界断裂，其构造特征的研究对区内大地构造演化有重要的启示作用。通过对康古尔塔格断裂带的地质特征、火山沉积建造及演化过程等方面的研究，发现康古尔塔格断裂带为韧性兼走滑特征深层次的剪切带；区内石炭系火山岩具有典型的沟-弧-盆体系火山-沉积建造特征；康古尔塔格断裂带到阿其克库都克断裂带之间的区域为准噶尔板块与塔里木板块之间的碰撞缝合带；早石炭-晚二叠世，康古尔大洋发生了颇具规模的南北双向俯冲，形成了康-阿缝合带，而康古尔塔格断裂带为康-阿缝合带的北部边界。

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.
