| 摘 要： | 石湖金矿区工业矿脉主要由101号脉和116号脉组成,前人研究多集中于101号脉而对116号脉关注极少。针对116号脉化探原生晕特征进行了系统研究,多元统计研究表明,116号脉最佳元素组合为:1Au+Ag+Cu+Pb+(Zn),代表主成矿元素组合;2As+Sb+Hg,代表头晕元素组合;3W+Mo,代表尾晕元素组合。元素等值线图及元素轴向分带显示,116-5-1号矿体元素分带具有"反分带"特征,表明116号脉深部具有较好的成矿远景。

| Abstract: | The industrial ore bodies in Shihu Gold District mainly consist of Vein 101 and 116,but compared to focused study on the former,Vein 116 gains little attention. The characteristics of primary halo of Vein 116 are systematically studied in this paper. The optimum elements composition determined by multivariate statistics is： 1Au ＋ Ag ＋Cu ＋ Pb ＋（ Zn）,the mineralization elements composition; 2 As ＋ Sb ＋ Hg,the front halo elements composition;3W ＋ Mo,the rear halo elements composition. The section isograms and axial zonation calculation indicate that the elements in Vein 116 is of ＂ Reverse Zonation＂,which shows that the deep part of Vein 116 bears prospects in mineralization. |
