摘要:
摘要: 通过研究江苏邳州花山子古锆砂矿的成矿地质背景、矿区地质特征、矿石类型、矿物组成、化学成分和放射性异常特征,借鉴现代锆砂矿成矿机制,进一步探讨花山子古锆砂矿的地质特征及找矿方向。花山子古锆砂矿是沉积砂矿床类型,赋存于中寒武世徐庄组中上部粉砂岩中,放射性元素钍含量高于一般粉砂岩钍含量,是古锆砂矿重要的找矿标志。徐庄组主要分布在徐州北部地区,汴塘耿庄、大泉焦庄和台儿庄高山等地区具有较好的找矿前景。
Abstract:
Abstract:On the basis of metallogenic geological background, ore type, mineral composition, geochemical composition and radioactive anomaly of the ancient zircon placer in Huashanzi, Pizhou, Jiangsu Province, this study further discussed the geological characteristics and prospecting direction of the ancient zircon placer, combined with the metallogenic mechanism of the modern zircon placer. The Huashanzi ancient zircon placer is a new type of sedimentary sand deposit, which occurs in the siltstone of middle and upper Xuzhuang Formation of Middle Cambrian. Its thorium content higher than the normal value of ordinary siltstone is an important prospecting indicator of ancient zircon placer. The Xuzhuang Formation widely distributed in the north of Xuzhou is of better prospecting conditions, while preferential areas for ore exploration are concentrated in Gengzhuang of Biantang, Jiaozhuang of Daquan and Gaoshan of Taierzhuang.
