增生造山带的构造是理解大陆生长的关键。本文对中亚西部造山带的造山成分及其融合进行了综述。CAOB记录了日本型、马里亚纳型和阿拉斯加-阿留申型弧系等不同类型造山带的汇聚和相互作用，以及西伯利亚克拉通的活动边缘层序，包括广泛的增生杂岩和增生弧地体。在CAOB构造过程中，哈萨克斯坦弧链以多次俯冲为特征，而塔里木克拉通北缘则以被动边缘为主。在晚古生代甚至早三叠世，各造山组分之间的多次辐合和增生形成了巨大的造山拼贴，包括平行合并、环微大陆合并和造山斜弯曲。圈闭盆地的保存在造山过程中发挥了重要作用，海洋板块的一些部分被俯冲，而其他部分则表现为刚性单元。CAOB的造山作用是长期的，持续时间超过800 m.y，涉及多次俯冲和长期持续的增生，具有增生造山和大陆生长的复杂性。
The architecture of accretionary orogens is a key to understand continental growth. Here we present an overview of the orogenic components and their amalgamation in the western Central Asian Orogenic Belt (CAOB). The CAOB records the convergence and interactions among various types of orogenic components including the Japan-type, Mariana-type, and Alaska–Aleutian-type arc systems, as well as the active marginal sequences of the Siberia Craton, which incorporated wide accretionary complexes and accreted arcs and terranes. During construction of the CAOB, the Kazakhstan arc chain was characterized by multiple subduction, whereas the northern fringe of the Tarim Craton remained mostly as a passive margin. The multiple convergence and accretions among these various orogenic components generated huge orogenic collages in the late Paleozoic and even in the early Triassic, involving parallel amalgamation, circum-microcontinent amalgamation and oroclinal bending. The preservation of trapped basins played a significant role in orogenesis with some parts of the oceanic plate being subducted and others behaving as rigid units. The orogenesis in the CAOB was long-lived, lasting for more than 800 m.y., involving multiple-subduction and long, continuous accretion, and featuring the complexity of accretionary orogenesis and continent growth.
