摘要
以新疆梧南金矿区地质背景和矿床原生晕研究为基础,以4号勘探线为代表区段,采集4个钻孔的193件地球化学样品进行金、银、砷、锑、汞、铜、铅、锌、铋、钼10项元素的测试分析和资料整理、统计制图等,对元素组合及相关关系进行统计分析。结果表明:金与尾部元素呈正相关,与前缘元素呈负相关。首次建立了该矿床的原生晕分带,从前缘到尾部为:金—铋—铜—钼—汞—锑—银—砷—铅—锌,从而确定了该矿床的地球化学原生晕叠加模型:上部矿体的尾晕与下部矿体的前缘晕叠加到一起,形成尖灭再现或尖灭侧现的原生晕叠加形态。
According to the geological background of the mining area and the primary haloes of Wunan gold deposit, the authors tested Au, Ag, As, Sb, Hg, Cu, Ph, Zn, Bi and Mo of 193 geochemical samples from 4 boreholes of the 4th exploration line and statistically analyzed the element association and correlation. The results show that Au is positively correlated with rear elements and negatively correlated with front elements. The primary halo zoning of the deposit was built in detail for the first time, from the front to the rear: Au-Bi-Cu-Mo- Hg-Sb-Ag-As-Pb-Zn, and then the superposition model of the geochemistry of the deposit was set up. The trailing halo of upside and the front halo of underside are superimposed. As a result, the stacked primary halo shape of reappearance and side appearance is formed.
