| 摘 要： | 简要叙述了岩石圈均衡补偿深度和弹性板复合补偿的理论与方法;求出了亚洲中部地区岩石圈均衡的最佳补偿深度为75km,通过线性反演得到该区岩石圈弹性板复合补偿模型的基本参数。指出粘滞系数较低的上地幔75km附近存在的低粘滞度的软流层,可能是达到该区大范围岩石圈均衡的大体部位,并对亚洲中部地区大陆弹性板机制等问题进行了讨论。

| Abstract: | In this article, we relate the theory with the methods of the equilibrium compensation depth of the lithosphere and compound compensation of elastic slab. Then we get the best lithospheric equilibrium compensation depth of 75 km in the Central Asian Region and the basic parameters of the lithospheric elastic slab in this region by linear inversion. We conclude that the asthenolayer with the low cohesion in the depth of 75 km in the upper mantle of low cohesion coefficient may be the approximate position of the large-scale lithosphere equilibrium in this region. Moreover, we discuss the mechanism of the elastic slab of the Central Asian Region lithosphere. |
