This paper deals with the relationship between the Moho and the ore concentration  areas through reconstruction of the Moho 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.
