Under guidance of the theory of plate tectonics, according to geology, geophysical and geochemical exploration, remote sensing data, and comprehensive analysis of research results about the plate tectonics in Eastern Tianshan Orogenic Belt, the authors redefined the location of suture zone between the Junggar-Kazakhstan and Tarim Plates, and concluded that the zone among Kangur and Aqqikkudug faults is the suture zone between the Junggar-Kazakhstan and Tarim Plates in Eastern Tianshan Orogenic Belt. The above suture zone has an independent tectonic unit that possesses its material entity, its special tectonics and structures. It also controls the polymetallic metallogenic belt in
