摘要
东秦岭深地震剖面上反映的华北、秦岭和扬子莫霍地震波组的特征具有明显差异。通过对莫霍地震波组特征的研究,指出秦岭壳幔过渡带的不均匀程度和厚度大于华北和扬子壳幔过渡带。受地壳均衡作用的影响,已形成的秦岭壳幔过渡带起到了通常所说的“山根”作用。
There are obvious differences about the Moho seismic event features of the plate of north China and Yangtze as well as Qinling orogenic belt appeared on Eastern Qinling deep seismic profile. This paper indicates that the inhomogeneity and thickness of eastern Qinling orogenic belt Moho are larger than North China and Yangtze Moho, through researching Moho seismic event features. The Qinling Moho zone formed after crust balance play so-called “the foot of a hill” role.
