| 中文摘要: |
| 为有效划分申家窑金矿床成矿阶段,更好地指导矿床开展地质调查工程,本次工作以成矿成晕元素原生晕地球化学组合特征为研究对象,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:相关性特征显示与Au相关性较好的元素有Cu、Pb、Zn、Sb、Ag和Bi,表明相似的分布规律和富集规律；聚类分析研究认为Pb、Zn、Au、Sb、Cu、Bi、Ag为一类,表现为主成矿元素之间的关系,为重要的地球化学找矿标志。因子分析获得三个主因子,其中第一主因子(F1)为Ag、Zn、Pb、Bi、Au、Cu、Sb占据主导位置,显示Ag、Zn、Pb、Bi、Cu、Sb与Au矿化密切相关,推测为一次中低温成矿阶段,为主要的成矿作用；成矿活动划分为3个阶段,分别为石英—菱铁矿阶段、石英—多金属硫化物阶段以及石英—黄铁矿阶段。根据矿床原生晕组合特征和分带特征,对矿床开展了深部找矿预测,显示了良好的深部找矿前景。通过上述研究工作,深化了崤山地区成矿规律认识,为申家窑金矿床乃至崤山地区金矿地质调查工作提供理论支持。 |

| It is necessary to effectively identify metallogenic stage for guiding the geological survey engineering of Shenjiayao gold deposit. With the combination of primary halos geochemical characteristics as the research object, using SPSS software tocarry out the correlation analysis, cluster analysis, and factor analysis, such as combination characteristic research, and combined with the mine geological characteristics and predecessors’ studying results, preliminary has been divided into three metallogenic stages. The results are as follows:The correlation characteristics show that the elements with good correlation to Au include Cu, Pb, Zn, Sb, Ag and Bi, indicating similar distribution and enrichment rules. Cluster analysis shows that Pb, Zn, Au, Sb, Cu, Bi and Ag belong to a class, which shows the relationship between the main ore-forming elements and is important geochemical prospecting indicators. Three main factors were obtained by factor analysis. The first main factor (F1) was Ag, Zn, Pb, Bi, Au, Cu and Sb, which showed that Ag, Zn, Pb, Bi, Au, Cu and Sb were closely related to Au mineralization. It was speculated that it was a middle-low temperature mineralization stage and was the main mineralization process. The mineralization stage can be divided into three stages:quartz-siderite stage, quartz-polymetallic sulfide stage and quartz-pyrite stage respectively. Based on the characteristics of primary halo assemblage and zonation of the deposit, deep prospecting prediction has been carried out, which shows a good deep prospecting prospect.The above-mentioned work has deepened the understanding of metallogenic regularities, and provided theoretical support for the geological survey engineering of Shenjiayao gold mine and even the Xiaoshan region. |
