地球化学找矿是青城子矿区重要的找矿手段.早在五十年代末和六十年代初,地质部物探所与原一○六队配合,相继在本区开展了大量原生晕试验和生产工作,总结出了评价矿致异常的三项指标(Pb>300ppm,As>100ppm,Cu/Pb<0.2),取得了一定的地质效果,为我国岩石地球化学找矿工作的开展做出了贡献. 近年来,矿区地质和地球化学找矿工作的深入发展及实践证明,用上述三项地球化 Geochemical prospecting is an important means of prospecting in the Qingchengzi mining area.As early as the late 1950s and early 1960s, the Geophysical Agency of the Ministry of Geology, in cooperation with the original 106 teams, has conducted a large number of primary halo tests and production in this area (Pb> 300ppm, As> 100ppm, Cu / Pb <0.2), some geological results have been obtained, which has contributed to the development of geochemical prospecting in China In recent years, the further development and practice of geology and geochemistry prospecting in the mining area have proved that with the above three geochemical
