摘要
阐述了一个新的铀成矿类型——构造-油气型;讨论了该类型砂岩铀矿床形成的区域背景、构造特点、成矿环境、矿化特征和矿床成因;认为与传统的层间氧化带型砂岩铀矿床不同;强调贯通型断裂构造和油气对铀成矿所起的重要作用,对今后砂岩型铀矿普查勘探有一定的参考价值。
A new sandstone uranium metallogenetic type-structure-oil gas type is elaborated in this paper, and the regional setting, structure features, metallogenetic environment, uranium mineralization characteristics and genesis are discussed in detail. The new structure-oil gas type is different from traditional interlayer oxidation zone type uranium deposits, penetrating fault and oil gas play much more important role in new type uranium mineralization. The new type is of significance in uranium reconnaissance and exploration.
