| 摘 要： | 准噶尔地块为前震旦纪地块。古生代,本区进一步演化成为一个由大陆裂谷发育起来的不成熟洋壳——准噶尔海槽。该海槽向西可与苏联巴尔喀什相通,并将哈萨克斯坦古板块肢解为南、北两大陆块。早石炭世末,本区结束了洋壳历史,重新成为大陆克拉通,托里北——达拉布特一线为缝合线位置。中石炭世以后,以碰撞后构造为主导,发生过三次明显的块断运动和A型俯冲。北东向的达拉布特断裂系就是在本区地壳缩短的背景下产生的走滑断层和推覆构造

| Abstract: | Zhungeer block is the Pre-Sinian block. In the Palaeozoic era the reg ion was further evolved into a mature ocean crust that was developed from the con tinental split-valleys-the Zhungeer trough. The trough was adjacent to Buerkashi of the Soviet Union in the west and dismenbered Kazahstan palaeoplate into both the south continent and the north continent.In the end of the Early Carboniferous, the history of the ocean crust was ended and became the continental craton again. The suture was situated in the line of the northern Touli-Dalabute . After the Middle Carboniferous Epoch three obvious block-faulting movements and the A-type subduction had taken place with the subduction structure being as the predominatiog role. The NE-trending Dalabute fault system was the strike-slip faulting and thrusting structure on the basis of shorting the earth's crust in the region. |
