Like Europe, most of China has secondary crust with a Moho of 30-40 km. This thickness tapers towards its margins (coastal areas). More recently, much of the crust has suffered lateral forces from the ocean bed-crust of the Pacific area, and this has led to severe slip/shear faults and deformation (mountain building). Indeed, 80% of China’s topography is mountainous and there are several fault lines running east to west. Southern parts of China have been pushed more westwards than more northerly parts. This phenomenon became evident when I was piecing together the continents on Pangaean Earth Model.
