摘要:

摘要:文中以板块构造理论为指导思想,以大量地质、物探、化探、遥感资料为依据,在全面分析前人对东天山造山带板块缝合线的认识基础上,重新厘定研究区准噶尔—哈萨克斯坦板块与塔里木板块缝合带的位置。经研究确定:东天山造山带康古尔塔格和阿齐克库都克两条断裂之间所夹持的区域,为准噶尔—哈萨克斯坦板块和塔里木板块陆陆碰撞的缝合带,即康古尔塔格—阿齐克库都克碰撞缝合带。该碰撞缝合带既有板块边界划分意义,又有实体物质组成和特定结构、构造及其演化历史的独立构造单元,也是东天山地区重要的多金属成矿带,故该带对东天山造山带Cu、Ni、Au、Ag等多金属矿产的形成和空间分布起着重要的控制作用。

Abstract:

Abstract:  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, we 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 Eastern Tianshan. Consequently, the suture zone played an important role in mineralization and spatial distribution of copper, nickel, gold, silver and other polymetallic deposits.
