Abstract: A detailed knowledge of the thickness of the lithosphere in the North China craton (NCC) is important for understanding the significant tectonic reactivation of the craton in Mesozoic and Cenozoic. We achieve this goal by applying the newly proposed continuous wavelet transform theory to the Gravity Field Model (EGM 2008) data in the region. Distinct structural variations are identified in the scalogram image of profile Alxa-Datong (大同)-Qingdao (青岛)-Yellow Sea (profile ABC), transversing the main units of NCC, which we interpret as mainly representing the Moho and lithosphere- asthenosphere boundary (LAB) undulations...
