Shallow crust metallogenic mechanism is closely related to different types of deep-seated structures. The Moho can well indicate the deep tectonic characteristics. This paper deals with the relationship between the Moho and the ore concentration areas through reconstruction of the Moho based on regional gravity data obtained in Hebei Province. Large-size gold, lead-zinc and other ore deposits are existent in the mantle slope zone; polymetallic and sedimentary ore deposits occur in the mantle-terrace area, with the sizes being smaller than those in the mantle slope zone; large-size coal, oil and some other sedimentary ore deposits are abundant in the mantle uplift zone; lead, zinc and other polymetallic ore deposits are abundant in the mantle depression zone.
