摘要:
义兴寨金矿床是山西省规模最大的金矿床，其深部成矿潜力如何及是否发育隐伏矿体，是矿山亟待解决的实际问题。在对成矿特征、控矿因素和矿床成因有比较全面认识的基础上，采用矿床原生晕地球化学法对义兴寨金矿床铁塘硐矿段开展了深部找矿预测研究。原生晕异常显示，在6勘探线深部400~550 m标高和0 m标高附近存在2个主要Au异常中心，且0 m标高附近金矿化规模最大，异常区即推测矿体范围。原生晕元素轴向分带序列自上而下为：Sb-Mn-Mo-W-Ni-B-Sn-P-Au-Hg-Cr-Co-Cu-Pb-Zn-Ag-Bi-As-Ba。因此，认为铁塘硐矿段深部具有很好的成矿潜力，推测在深部-400~-500 m标高附近区域存在规模较大的富矿段。预测成果得到了近期布置钻探工程的验证，新增金资源量8 t，为进一步深部找矿工作提供了可靠支撑。

Abstract:
The Yixingzhai Gold Deposit is the largest gold deposit in Shanxi Province.The practical problems urgently to be solved are to explore the deep ore genesis potentials and identify developed concealed ore bodies.With a comprehensive understanding of mineralization characteristics,controlling factors,and ore genesis,the primary halo geochemical method of deposits was utilized to conduct deep mineral exploration prediction research on the Tietangdong ore section of the Yixingzhai Gold Deposit.The primary halo anomaly shows that there are 2 main anomaly centers for Au at elevations of 400 m to 550 m and 0 m,with the largest scale of gold mineralization near the 0 m elevation.The anomaly area is exactly the inferred range of the ore body.The element axial zoning sequence of the primary halo from top to bottom was obtained as follows:Sb-Mn-Mo-W-Ni-B-Sn-P-Au-Hg-Cr-Co-Cu-Pb-Zn-Ag-Bi-As-Ba.Therefore,it is believed that the Tietangdong ore section has good prospecting potential in the deep.It is speculated that there may be a large-scale ore shoot near the elevation from - 400 m to - 500 m.The prediction results have been verified through drilling recently deployed,and an additional 8 tons of Au reserve have been added,providing reliable support for further prospecting work.
