Based on research results at home and abroad, this paper studies the geochemical characteristics of trace elements of mantle domains such as DMM, HIMU, EM1 and EM2 defined by isotopic geochemistry, and discusses the genesis of those end-member components.

Based on the detailed contrast between the chondrite normalized REE patterns and REE geochemical evolution law, this paper proves that the ore bearing fluid for the Carlin type gold deposits in the area mainly originates from the upper mantle differentiation, and that the crust (strata) matter partly contaminates the plutonic ore bearing fluid during moving from mantle to crust.

Based on the detailed calculation of Pb isotope compositions, it is proved that the ore bearing materials and fluids of Carlin type gold deposits in the area mainly originate from the upper mantle differentiation, and that the crust (strata) matter partly contaminates the plutonic ore bearing fluid during transportation from mantle to crust.
