| 中文摘要: |
| 蒙古国东部省道尔脑德地区于侏罗纪-早白垩世火山活动频繁，形成道尔脑德火山机构，发育基性-酸性双峰式火山熔岩及火山碎屑岩，夹有陆源碎屑岩。同期该区域由挤压到伸展的构造体制转变，构造-岩浆热作用强烈，发生大规模成矿作用，形成与火山热液有关的铀-贱金属-金-萤石矿床成矿系列。文章在分析不同矿床成因类型、成矿时代及成矿温度基础上，系统总结该矿集区铀-贱金属-金-萤石矿床系列成矿作用。综合分析矿床产出背景、岩矿关系及各类控矿要素基础上，提出围岩、蚀变、构造、地球化学及岩石物理等方面的找矿标志。 |
| 英文摘要: |
| Violent volcanism took place in Jurassic-Early Cretaceous Epoch with Darnold volcanic edifice and basic-acid two model volcanic lava and pyroclastic rock intercalated with terrestrial classic rocks. At the same time regional compressional regime turns to the tensional accompanied by tectonism and magmatism and large scale metallogenesis. The U-base metal-Au-fluorite serial deposits are formed in the area. Genetic types, metallogenic times and temperatures of the serial deposits, the ore-forming process, occurrence background, relation between the rock and the ore and different ore-control factors are comprehensively analyzed and are put forward the ore prospecting marks in respect of wall rock, alteration, structure, geochemistry and petrophysics. |
