英文摘要The Moho is a discontinuity separating the crust from the mantle. However, the Moho cannot be simply represented by a sharp discontinuity but a transition with thickness ranging from several kilometers to tens of kilometers. The transition could reveal the interactions between the crust and the mantle. Combining the results of deep seismic sounding, wide-angle seismic refractions and high-temperature high-pressure experiments, the paper determines the range of P wave speed of the crust-mantle transition to be 6.8 similar to 7.5 km center dot s(-1). The mean thickness of the crust-mantle transition is 5 similar to 10 km beneath eastern China. The thinnest crust-mantle transition occurs beneath Sichuan Basin, the core of Yangtze Craton. The crust-mantle transition beneath Trans-North China Orogen (TNCO) is as thick as similar to 30 km. With geochemical evidences, the thick crust-mantle transition might be attributed to underplating and accumulation of mantle magma.
