| 摘 要： | 利用中国陆地 10条GGT地球物理资料编制中国岩石圈篱笆图 ,并加以说明。通过对地球物理特征和地质学分析 ,认为以大兴安岭—太行山—武陵山重力梯级带和青藏高原周边重力梯级带为界 ,可把中国陆地划分 3个岩石圈构造单元。中国陆壳既有三分结构也存在二分结构 ;对地壳中存在的低速带、高导带和天然地震带进行了划分。以大兴安岭—太行山—武陵山重力梯级带为界 ,两侧盆地具有不同的地球物理特征 ,这些特征与构造运动、均衡调整过程有关。莫霍面几乎遍布全国 ,它具有内部结构。下部地壳底部存在的地球物理异常与莫霍面有关 ,也可能与岩石圈地幔的变化有关。 |
| 关 键 词： | 岩石圈结构篱笆图 地学断面 岩石圈构造单元 中国陆壳 莫霍面 |

| Abstract: | We edited and explained the fence diagram of lithosphere structure in China by using the geophysical data of 10 GGTs in China continent. Through correlation on the geophysical characteristic and geological analysis, we achieved some conclusions. Firstly, China continent can be divided into three lithospheric tectonic regions and the edges of the regions are the gravitational gradient zone in Daxing'an Mountain-Taihang Mountain-Wuling Mountain and the gravitational gradient zone around Qinghai-Tibet Plateau. Secondly, China continental crust has not only trisection structure but also dichotomy structure. Finally, a series of low-velocity zones, high-conduction zones and earthquake belts were identied . At the both side of the gravitational gradient zone of Daxing'an Mountain-Taihang Mountain-Wuling Mountain, the basin has different geophysical characteristics, which is connected with the course of the tectogenesis and the isostatic adjustment. Moho has inner structure and can be found all over the continent. The geophysical anomaly in the bottom of lower crust may be connected with Moho or the change in the top-part of the mantle. |
