摘要

In this paper, the authors calculated the receiver functions for each of the seismic stations, and inverted for the distributions of crustal thickness and Poisson ratio for the NCC (North China Craton) with fine spatial coverage. There are three characteristics of the crustal thickness and the Poisson ratio: 1) crustal thinning process not only occurs in the east part of NCC, but also extends to the North South Gravity Lineament; and 2) crustal thinning also occurs in the rifts and basins surrounding the Ordos Block, and the Poisson topography, which may imply that the NCC crust is experiencing a slow process of destruction and isostasy.
