| 摘 要： | 选择胶东玲珑金矿典型矿体47号脉为研究对象,应用基岩地球化学方法,测试微量元素含量,研究微量元素与金的相关关系、计算微量元素的浓集系数并确定其轴向分带,探讨微量元素对深部金成矿的指示意义,期待能对玲珑金矿深部找矿提供一些参考.初步认识如下:矿区金矿体的最佳指示元素依次为Au、Ag、Bi、As、Cu、Co、Mo、Sb；金矿体的轴向分带序列从上到下依次为As、Pb、Ag、Cu、Hg、Sb、Mo、Ni、Th、V、U、Mn、Zn、Bi、Co、Au；矿体中Au、Bi、Ag、As富集系数大,Cu、Co富集系数中等,而Zn在矿体中相对亏损.研究结果表明,在深部47号矿体仍有较好的成矿前景. |

| Abstract: | After years of mining, the reserves of Jiaodong Linglong gold deposit have been consumed enormously. Therefore, the prospecting of reserve resources has become an urgent problem. In this paper, by using the application of rock geochemical method and choosing the typical ore 47 vein as the object of study, the trace elements related with Au had been tested and the correlation between trace elements and Au had been researched. Then, the concentration coefficient and axial zoning had been calculated and the indicative significance of trace elements to deep Au mineralization had been discussed. Finally, looking forward to some reference can be provided for the prospecting of Linglong gold deposit at depth. Some preliminary recognition as followed that the optimal indicator elements in gold ore body is Au, Ag, Bi, As, Cu, Co, Mo and Sb successively; the axial zonality sequence from top to bottom is As, Pb, Ag, Cu, Hg, Sb, Mo, Ni, Th, V, U, Mn, Zn, Bi, Co and Au; the enrichment coefficient of Au, Bi, Ag is big, Cu and Co is medium, Zn is of relative depletion; and the mineralization prospect of No.47 ore body is good in deep. |
