本文通过对安徽矿集区域地质背景的分析,得出该区域地球化学特征,从而引出对找矿方法的研究。安徽矿集区水系沉积物异常面积大,元素组合复杂,各种单元素异常套合好或较好。均有明显的浓集中心.尤其是在异常区的南部,异常分带性明显。尤其Cu、Ag、Pb、Zn、Sn、Bi等元素呈现高度富集,异常强度高。土壤异常各种元素峰值也十分突出,Cu、Ag、Au、Zn、Sn等元素高值点比较集中,与水系异常浓集中心相吻合。经专家探究,铜、银、钼矿化现象在岩体与围岩接触带上有出现,测试结果表明部分样品已达到或超过工业品位,无论是水系沉积物异常,还是土壤异常,都显示了该处具有极为良好的成矿条件及地球化学背景。
Based on the analysis of the geologic background of the ore-collecting area in Anhui Province, the geochemical characteristics of the area are obtained, which leads to the research on the prospecting methods. The anomaly areas of sediments in Anhui mining area are large, the elemental composition is complex, and all kinds of single element anomaly are good or better. There are obvious concentration centers, especially in the southern part of the anomaly, with obvious zonation. In particular, Cu, Ag, Pb, Zn, Sn, Bi and other elements showed a high degree of enrichment, abnormal strength. The peak values of various elements of soil anomalies are also very prominent. The high values of Cu, Ag, Au, Zn, Sn and other elements are concentrated and coincide with the anomalous concentration centers of water systems. After the experts explored, the mineralization of copper, silver and molybdenum appeared in the contact zone between rock mass and surrounding rock. The test results showed that some samples had reached or exceeded the industrial grade, both of which were abnormal in sediments and abnormal in soil The area has very good metallogenic conditions and geochemical background.
