摘　　要：通过对贾公台金矿开展系统的原生晕研究工作,初步建立了矿区原生叠加晕轴向分带(自上而下):W-Mo-Bi-Ni-Co-Cu-Zn-Pb-Ag-Au-Sb-As,认为区内成矿热液具有多期次叠加成矿的特点,深部前缘晕元素异常发育,预示深部找矿前景较好,预测深部盲矿靶位在3200 m标高以下。Through a systematic study of primary halos in the Jiagongtai gold deposit,we have established a axiial zonation for structural superimposed halos in the mine area（ from upper to lower） ： W-Mo-Bi-Ni-Co-Cu-Zn-Pb-Ag-Au-Sb-As. We think that this ore-forming hydrothermal area is characterized by multi-period stacked mineralization. Numerous frontal halo anomalies exist at depth,indicating a good prospect of ore-search there. It is forecasted that the deep blind ore targets are below 3200 m nominal elevation.
