  • 图  1  Yang等(2022)得到的东准噶尔地区地壳结构与地磁异常三维视图. 正地磁异常标志着古生代岛弧的位置;莫霍面片段1、3、5代表岛弧的莫霍面;莫霍面片段2、4、6代表海洋盆地的莫霍

    Figure  1.  A 3D view of the deep structure and magnetic anomalies across Northern Xinjiang by Yang et al. (2022). Paleozoic island arcs are illustrated by positive magnetic anomaly strips; Moho fragments 1, 3, and 5 represent the moho of arcs, whereas fragments 2, 4, and 6 represent the moho of intra-arc basins

    图  2  Yang等(2022)提出的哈萨克斯坦山弯构造对准噶尔地区海洋盆地保护作用示意图. T代表塔里木块体;T-M代表图瓦—蒙古山弯构造,古亚洲洋俯冲回撤在其南缘形成了一个多岛海系统;K代表哈萨克斯坦山弯构造. 马蹄形的哈萨克斯坦山弯构造在与塔里木块体和图瓦蒙古山弯构造碰撞过程中吸收了大部分的应力,因此其内部的多岛海系统受其保护得以保存下来

    Figure  2.  Tectonic model of trapped oceanic basins protected by the Kazakhstan orocline during multiple amalgamations by Yang et al. (2022). T: Tarim craton; T-M: Tuva-Mongol Orocline, which contains an archipelago system on its southern side, generated by subduction retreat of the Paleo-Asian Ocean slab; K: Kazakhstan orocline. The Kazakhstan orocline is a huge U-shaped structure that bore the main stress of the collision and protected the inside archipelago
