| 摘 要： | 准噶尔造山带地壳结构复杂 ,构造形态多样。根据地球物理资料 ,特别是国家“30 5”项目可可托海至阿克塞地学大断面反映出 ,准噶尔造山带至少由四个不同时代、不同性质的地质块体拼合而成。地体间为深断裂或超岩石圈深断裂分隔。在地块内部不同层次之间也常有巨型水平剪切或滑脱带存在 ,造成了准噶尔造山带在垂向上有明显的分层性 ,在横向上具有不均一性和不连续性。 |
| 关 键 词： | 准噶尔 地壳结构 超岩石圈断裂 地体拼合 |

| Abstract: | The crustal structure of Junggar orogenic belt is very complex.It has a diversity of structural patterns based on the geophysics data,especially the geo section from Keketokay to Shankou reflects that the Juggar orogenic belt was composed by at least 4 blocks with different property and forming time.The blocks were separatecl by deep fractures.Inside the blocks,there were also some large scale shear sones or glide belts which has a discontinous and uneven feature in horizontal direction. |
| Keywords: | Junggar crustal structure Moho fault terrain patching |
