| 摘 要： | 野外地质调查表明孟营子地区成矿地质条件优越,具有中-大型规模的银铅锌矿找矿潜力。为了进一步确定有利找矿靶区,进行了1:2.5万地球化学扫面工作。土壤元素浓集系数和变异系数综合分析表明Ag、Au、Cu、Pb、Zn、As等元素在区内局部富集,是主要的成矿元素;根据相关性分析结果绘制的多元素综合异常图也反映出主要成矿元素异常浓集中心明显,与已发现矿体、矿化蚀变体吻合好。结合地表填图和探槽工程揭露结果,圈定了6处综合异常作为有利找矿靶区。

| Abstract: | The field geological investigation indicated that Ore-forming Geological Conditions of Mengyingzi area is favorable, and this area has benign prospecting potential. We try to find out the prospecting target area with the 1：2500 geochemical survey. Both coefficient of concentration and Coefficient of variation in soil elements showthat Ag, Au, Cu, Pb, Zn and As are the main ore forming elements. Base on the results of correlation analysis, integrated anomaly maps were drawn. The map indicated that ore forming elements had obvious abnormal concentration center which are consistent with the ore deposits or mineralized bodies. Combine with the results of geological mapping and trough unmasked, six anomalies were delineated as the prospecting target area. |
