２０多年来，我国地矿部门开展的地球化学填图工作覆盖了全国６００多万km２，获得了数以千万计的数据。地质工作者根据这些数据发现在巨型矿床周围存在着巨大的套合地球化学模式谱系，巨量的物质供应是形成巨型矿床的关键因素，形成了地球化学块体新理论。目前，中国地质调查 For more than 20 years, the geochemical mapping work carried out by China’s geology and mining department has covered over 6 million km2 nationwide and obtained tens of millions of data. Based on these data, the geologists found that there is a huge genealogical geochemical pattern pedigree around the giant deposits. The huge amount of material supply is the key factor for the formation of giant deposits, forming a new theory of geochemical blocks. At present, China’s geological survey
