Recent studies reveal the widespread occurrence of mid-lithospheric discontinuities (MLDs) in continental lithosphere, yet their origin and role in lithospheric evolution remain debated. We present a high-resolution three-dimensional electrical resistivity model of the North China Craton (NCC) to characterize the electrical properties of the seismically defined MLDs. The NCC comprises the thinned eastern NCC, the Trans-North China Orogen (TNCO), and the stable western NCC, dominated by the Ordos
