| 摘 要： | 三道湾子金矿位于大兴安岭燕山期成矿带东南部,属于典型的富碲贫硫石英脉型金矿。以此为例,研究了该类矿床矿床原生晕的分布特征,并采用格里戈良分带指数的改进方法计算了原生晕轴向分带序列和分带指数,目的是揭示该类矿床的勘查地球化学特征,并为该矿区进一步找矿指明方向。研究结果表明,原生晕轴向分带序列为:Mo-Sb-Pb-As-Bi-W-Zn-Ag-Cu-Hg-Te-Au。w(As)·w(Sb)]/w(Au)·w(Zn)]、w(Sb)·w(Mo)]/w(Au)·w(Zn)]、w(As)·w(Sb)·w(Mo)]/w(Au)·w(Cu)·w(Zn)]等分带性指数指示主成矿元素Au、Ag在130中段下方异常形态尚未封闭,Ⅰ号矿体深部仍有找矿的潜力,矿石品位会有所降低。

| Abstract: | The Sandaowanzi gold deposit is located in the southeast of the Yanshannian Da Hinggan Mountains metallogenic belt. The a-nomaly distribution of primary halos and the characteristic distribution of elements were studied in this paper. Based on the data calcu-lated by the improved method of Gregorian＆#39;s zoning index, the zonal sequence of the primary halo is Mo-Sb-Pb-As-Bi-W-Zn-Ag-Cu-Hg-Te-Au. The zonal index comprising such associations as As＆#183;Sb/Au＆#183;Zn, Sb＆#183;Mo/Au＆#183;Zn, As＆#183;Sb＆#183;Mo/Au＆#183;Cu＆#183;Zn was used for the prediction of the deep ore bodies, which provides the basis for further prospecting in this mining area. |
