Abstract

Abstract

The amount of extension and shortening of the crust of the Qinghai-Tibet plateau is roughly calculated from its thickness using the method of balanced section.The results show that it has shortened about 1400km in the N-S direction and extended 25~30km in the vertical direction.Such a tremendous shortening and extension may indicate that the crust of Qinghai-Tibet plateau behaves as a elasto-viscous rather than rigid body.
