| 中文摘要: |
| 额济纳旗辉森乌拉金矿是近年发现的金矿床,矿床产于华力西晚期二长花岗岩体与二叠系上统哈尔苏海组外接触带部位,矿化类型为石英脉型金多金属矿、蚀变岩型金矿。矿体呈层状、似层状,严格受岩体和地层特定层位控制；金矿化与区内石英脉、片理化蚀变带关系密切,化探异常与侵入岩体的分布密切相关,石英脉是重要的找矿标志之一。文章通过深入研究该矿床区域成矿构造地质背景和区内成矿地质条件,总结主要控矿因素,分析探讨了区内找矿前景,进而提出了进一步找矿方向。 |
| 英文摘要: |
| The Huisenwula gold deposits in Ejina was discovered in rencent years, it is produced in The Harsuhai Formation of the Upper Permian in the outer contact zone of the late Variscan monzogranite.The types of mineralization are altered quartz vein type gold polymetallic deposit and rock type gold deposit. The ore layer is layered and like layered, it is strictly controlled by the rock and stratigraphy specific horizon.Gold mineralization is closely related to the quartz veins and the physical and chemical alteration zones in the area. The geochemical anomalies are closely related to the distribution of intrusive rocks. The quartz pulse is one of the important ore prospecting symbols.By studying the geological background and geological conditions of metallogenic tectonics in the region, The main controlling factors are summarized and the prospecting prospects are discussed in this paper, and further prospecting direction is put forward. |
