摘要
In this paper, the authors have summarized the results of the detection work,and discussed the Moho variation in this region. It is shown that in North China, the deepest Moho is beneath the Mongolia fold belt (48 km) and the shallowest Moho is in Bohai bay basin (28 km), whereas in the Northeast China, the deepest Moho occurs under Great Hinggan Mountains region (42 km), and the shallowest Moho is under the Yilan-Yitong (YY) fault zone (27 km). All features suggest that North China and Northeast China must have experienced the peri-Pacific tectonism, and the Great Hinggan Mountains-Taihang Mountains gradient zone limited the influence range of this tectonism.
