金矿成矿具有多期多阶段叠加成矿成晕的特点。中国金矿床原生晕轴向从上到下具有Ｂ－Ａｓ－Ｈｇ－Ｆ－Ｓｂ－Ｂａ→Ｐｂ－Ａｇ－Ａｕ－Ｚｎ－Ｃｕ→Ｗ－Ｂｉ－Ｍｏ－Ｍｎ－Ｎｉ－Ｃｄ－Ｃｏ－Ｔｉ正向分带序列。“反分带”序列的出现，说明有另一阶段形成的矿体头部或前缘晕的叠加，指示矿体向深部还有很大延伸或有第２个盲矿存在。矿体轴向地球化学参数在连续上升或下降时发生“转折”，指示矿体向下延伸较大；在矿体尾部及尾晕出现“转折”，指示深部还有盲矿存在。
Gold mineralization with multi-stage multi-stage superposition mineralization into the halo characteristics. The primary halo of China gold deposit has B-As-Hg-F-Sb-Ba → Pb-Ag-Au-Zn-Cu → W-Bi-Mo-Mn-Ni-Cd-Co-Ti To the banding sequence. The emergence of the “anti-zoning” sequence indicates the superimposition of the head or front halo of the ore body formed in another stage, indicating that there is a great extension of the ore body to the deep or that there is the second blind mine. Axial geochemical parameters of the ore body experienced a “turning point” ascending or descending continuously, indicating that the ore body extended downwardly more. At the tail and tail halo of the ore body, a “turning point” occurred, indicating the existence of blind ore in the deep part.
