The Mineralization Characteristics and Prospecting Significance of Huanghuagou Uranium Anomaly in Northern Junggar Basin,Xinjiang
摘要
Abstract
In recent years,good prospecting results of uranium exploration has achieved in the northern margin of Junggar Basin,such as Dingshan occurrences and Kamst prospects.The discovery of Huanghuagou anomaly provided important clues for the prospecting of'new area,new layers and new type'in the northern margin of the basin.Based on the geological survey and systematic sampling of the Huanghuagou uranium anomaly,this paper summarized the uranium mineralization characteristics and discussed the genesis of mineralization.The study showed that:1)The mineralization of Huanghuagou anomaly was mainly developed in the core of Honglishan anticline and the hanging wall of Tuoyila fault.2)The host rock is the fine-grained lithic sandstone,and conglomerate,with limonite mineralization and clay alteration.3)The compositional maturity of the ore-bearing sandstone is low in component and medium in structural maturity,which is the characteristics of the braided channel in the near-source alluvial fan.4)The next main target layer in Huanghuagou area is Lower Cretaceous Tugulu Group,and the main prospecting types are phreatic oxidation zone type and phreatic-interlayer oxidation zone type.The next prospecting work in the northern margin of Junggar Basin should pay attention to the uplift and depression tectonic units,the vicinity of the depression-controlling faults,the position of the target layer inheriting the sedimentary feature of the overlying strata.关键词
