中文摘要:
      为探寻镇宁-紫云地区重晶石的找矿靶区,本文通过对区内的矿床地质特征、地球物理、地球化学、岩相古地理等特征进行详细分析,探讨区内的重晶石的找矿潜力,预测区内找矿靶区。通过上述方法分析得出区内典型乐纪重晶石矿床属于超大型矿床,矿体产于泥盆系榴江组(D3l)地层中下部,自下而上分布Ⅰ、Ⅱ、Ⅲ矿层,初步分析属于热水成因矿床。在洗鸭河、喜然、小屯等地区,大面积的含矿地层埋藏地层深部,具有较大的找矿潜力。根据区内找矿潜力分析结果将洗鸭河地区、喜然地区、小屯3个找矿潜力大的区域圈定为最佳找矿靶区。
英文摘要:
      In order to explore the prospecting target area of barite in Zhenning-Ziyun area, this paper analyzes the geological characteristics, geophysical, geochemical and lithofacies palaeogeography of the deposit in detail, discusses the prospecting potential of barite in the area, and predicts the prospecting target area in the area. Through the analysis of the above methods, it can be concluded that the typical lepian barite deposit in the area belongs to the super large deposit, the ore body occurs in the middle and lower part of the Devonian Durojiang Formation (D3l), and the ore beds I, II and III are distributed from the bottom to the top, which belongs to the hydrothermal deposit. In Xiyahe, Xiran, Xiaotun and other areas, a large area of ore-bearing strata is buried deep in the strata, which has a great prospecting potential. According to the analysis results of prospecting potential in the area, three areas with large prospecting potential, namely, Xiyahe area, Xiran area and Xiaotun area, are defined as the best prospecting target areas.
