| 中文摘要: |
| 为更好地指导大华山金矿及其周边矿床开展地质勘查工作，本研究以成矿成晕元素原生晕地球化学分带特征为研究对象，利用 SPSS软件开展了元素相关性分析、聚类分析、因子分析等组合特征研究，并结合矿区地质特征和前人研究成果，取得如下认识:相关性特征显示 As、Sb、Hg、Ag、Pb、Zn、W与 Au有较好的相关性，说明有相似的分布、富集规律；聚类分析和因子分析研究认为 Zn、W、Pb、Hg，反映了矿床的成矿环境， Au、As、Sb代表了成矿元素组合特征， Sn、Mo、Cu指示高温环境，不利于 Au、Ag的富集成矿。使用格里戈良法确定矿床原生晕轴向分带序列，矿体呈现出前缘晕和尾晕元素相互叠加的现象，总体表现出“反向”分带特征。根据矿床原生晕剖面异常及轴向分带特征，总结原生晕找矿标志，对矿床开展了深部找矿预测，认为在 10线+150～-100 m内可能存在平行盲矿体、 -200～-400 m内主矿体可能尖灭再现。通过本研究深化了大华山金矿成矿规律认识，为该区金矿进一步勘查工作提供了理论支持。 |

| In order to better guide the geological exploration of Dahuashan gold deposit and its surrounding deposits，the primary halo geochemical zoning characteristics of ore forming halo elements are taken as the research object. SPSS is used to carry out the combination feature research such as element correlation analysis，cluster analysis andfactor analysis. Combined with the geological characteristics of the mining area and previous researchresults，the following understandings are obtained:Correlation characteristics showed that As，Sb，Hg，Ag，Pb， Zn，W had good correlation with Au，indicating similar distribution and enrichment laws；Cluster analysis and fac. tor analysis showed that Zn，W，Pb，Ag，Hg，Sb，Au and As basically reflected the combination characteristics of main and associated ore-forming elements and ore-forming environment，Au，As，Sb represent the ore-forming ele. ment association characteristics，Sn and Mo indicate that high temperature environment is not conducive to theenrichment and mineralization of Au and Ag. The axial zonation sequence of the primany halo is determined by theGrigorian method，and the characteristics of the pimary halo axial zonation are analyzed and studied. According tothe anomaly of the primary halo section and the characteristics of axial zonation，the prospecting mark of the primary halo is summarized，the deep prospecting prediction is carried out，and the deep prospecting direction is determined. Through this research work，the understanding of metallogenic regularity of Dahuashan gold deposit is deepened，and theoretical support is provided for further exploration of gold deposit in this area. |
