| 摘 要： | 地处华北地块和扬子地块之间的秦岭造山带是一个壳幔结构十分复杂的地带,它的形成、演化也有其漫长而复杂的过程。本文依据近年来在该地带及邻区取得的地球物理资料所显示的多种信息来推断其壳幔结构及其形成、演化的某些特征,并尝试利用反映不同深度范围物质密度分布不均信息的卫星重力资料,探讨其地球动力学等背景。

| Abstract: | Qingling orogen, which is located between Huabei block and Yangzi block, is a belt of complicated structure in the crust and upper mantle with a long evolution history. This paper interpretes some characteristics of the crust and upper mantle structure and its formation and evolution on the geophysical data from the area and its vicinity. The geody-namic background of this area is discussed in the light of satellite gravity anomalies which reflect density distribution at different depths. |
