| Abstract: | In this paper,a zoning model of ore deposit geochemistry is synthetically established from the facet of exploration geochemistry based on zoning of the granite-type deposits,in combination of anomalies of different elements,vertical variations of average contents and ratios.It is concluded that F,Li,Be,W,Sn,Nb,Ta,Cu,Mo,Bi,Ti are effective indices for exploring this type of ore deposits.And several geochemical evaluation indicators,such as the combination of anomalies,intensity,ratio,and so on,are described and summarized to analyze the front,nearby area and tails of the ore body. |
