Uninterpreted (top) and interpreted (bottom) seismic profiles (3D data) in the northern Longmen Shan area (BB, Line 790), showing the characteristics of thrust sheets, tectonic wedges, and foredeep. The location of this seismic line can be found in Figure 1(d). The vertical axis is in milliseconds and not converted to depth. The full names of abbreviations of the strata can be found in Figure 2.
