Abstract: Bairiqili Gold District is one of the integrated exploration work areas of Wulonggou Gold Mine.Qinghai Nuclear Industry Geological Bureau carried out systematic gold prospecting in this area from 2010 to 2015,which achieved certain geological results and showed a good ore prospecting prospect in the district.Based on the comprehensive analysis of the geochemical characteristics such as element combination,element correlation,spatial distribution characteristics,and the structural superimposed halo characteristics of the primary ore body in Ⅰ gold-bearing minera-lized altered fractured zone of Bairiqili Gold Deposit,the paper establishes the prediction model of structural superimposed halo,identifies the indicators for blind ore body prediction,and predicts the lateral distribution of known ore bodies and prospecting target area.The results of the structural superimposed halo study and prediction show that there is great prospecting potential in the deep part of Ⅰ mineralized altered fractured zone.
