摘要
库捷尔太铀矿床(又名512铀矿床)是中国第一个典型的层间氧化带可地浸砂岩型铀矿床,矿床形态、规模、品位和分布都受控于层间氧化带,而层间氧化带在空间上具有多层性、叠加性和分带性。本文通过对库捷尔太铀矿床层间氧化带展布、分带性、岩石特征和矿体分布,铀矿物和价态铀的分布组合特点的分析,来进一步认识层间氧化带可地浸砂岩型铀矿床成矿规律,丰富水成铀矿床理论,以便对今后在寻找这类矿床时具有一定的指导意义。
The Kujieertai uranium deposit （also known as No. 512 uranium deposit） is the first typical interlayer oxidation zone in-situ leachable sandstone-type uranium deposit in China. The morphology, size, grade and distribution of this ore deposit are all controlled by the interlayer oxidation zone, which spatially assumes overlapping, multilayer and zoning characteristics. The authors analyzed the distribution, zoning and rocks of the ore deposit as well as the distribution and portfolio features of uranium minerals and valence-state uranium with the purpose of further discovering the matallogenic mechanism of the in-situ leachable sandstone-type interlayer oxidation zones and enriching the theory of hydrogenous uranium deposits, which is of great value in search for this kind of uranium deposits.
