The magmatic activity could be divided to two stages in Chengchao ore district, Hubei: diorite in the early stage and granite in the latter stage.  The magma intruded in the mid-late Yanshanian period.  The correlation between the magma and mineralization is consanguineous and the Yanshanian magma is the source of ore-forming materials. The mineralization period could also be divided to two stages: magnetite ore in the early stage and metal sulfide ore in the latter stage. Magnetite stage is the main stage for mineralization.  The contents of rare earth elements indicate that the chondrite-normalized REE and LREE patterns of diorite have the strong reversed change with that of magnetite ore.
