摘要/Abstract

摘要： 一个完全发育的陆-陆碰撞造山带往往会形成双前陆盆地。库车前陆盆地和北塔里木前陆盆地构成了南天山造山带的双前陆盆地。前者是中生代南天山造山带陆-陆碰撞造山阶段的原前陆盆地,后者则是新生代南天山造山带大规模陆内逆冲推覆阶段所形成的新前陆盆地。库车前陆盆地被后期的造山作用严重破坏,其楔项带和前渊带的很大部分都已卷入了后期的造山作用。北塔里木前陆盆地是一个完整的前陆盆地,各沉积带发育齐全。分隔伊犁-中天山地块和塔里木古陆的古南天山洋盆于二叠纪末完全闭合东部可能早一些),两陆壳地块完全碰撞到一起,库车前陆盆地形成;新生代喜马拉雅造山作用的远程效应导致南天山造山带重新活动,发生陆内造山,形成北塔里木前陆盆地。

Abstract: A fully developed conti nent-continent colision orogeny can often form dual foreland basin. Kuqa and northern Tarim foreland basins constitute the dual foreland basin of south Tianshan orogeny. The former is a protoforeland basin formed during Mesozoic continent-continent collision of south Tianshan, and the latter is a neo-foreland basin formed during Cenozoic large-scale intracontinental overthrust of South Tianshan. Kuqa foreland basin was strongly deformed during the consequent orogenesis. Its wedge depozone and possibly part of foredeep depozone had been involved into the consequent orogenises. Northern Tarim foreland basin is an integrated foreland basin with all the depozones. The ancient south Tianshan oceanic basin w as completely closed by the end of Permian(probably earlier at the east part). Yili-Central Tianshan block and Tarim continent were fully collided. And Kuqa foreland basin was formed during this collision. The remote effect of Cenozoic Himalayan orogeny made south Tianshan orogenic belt reactive, emerging intracontinental orogeny. Northern Tarim foreland basin was formed during this intracontinental orogeny.

Key words: Tarim basin, Kuqa, foreland, southern Ti anshan fold zone, land collision, thrust nappe
