砂岩型铀矿中铀矿物U-Pb年代学研究现状及研究方向
|
摘要
该文基于中国地质调查局天津地质调查中心研究团队近年来的研究工作及对相关文献的综合研究,对砂岩型铀矿中一些重要铀矿物如沥青铀矿(晶质铀矿)、铀石、钛铀矿等的微区原位成因矿物学和U-Pb年代学研究现状进行了深入分析,提出新的研究方向,即通过采用二次离子质谱法、激光剥蚀多接收器电感耦合等离子体质谱法与电子探针化学分析法和同位素稀释-热电离质谱法相结合的方式,综合研究砂岩型铀矿中沥青铀矿(晶质铀矿)、铀石、钛铀矿等铀矿物和金红石、磷灰石等含铀矿物的微区原位成因矿物学和U-Pb年代学,探索砂岩型铀矿中矿石矿物的U-Pb同位素测年新方法,获取更精确的砂岩型铀矿成岩成矿的年代学信息。这对于全面准确地认识砂岩型铀矿床的生成和演化历史,建立砂岩型铀矿床的成矿新理论具有十分重要的科学意义。铀矿物测年新方法在砂岩型铀矿床的地质勘探中也有广阔的应用前景。
In recent years we have conducted in-depth studies on the genetic mineralogy and U-Pb geochronology of uranium minerals (uraninite,coffinite,brannerite,etc.)and U-bearing minerals (rutile,apatite,etc.)from sandstone-type uranium deposit,using jointly secondary ion mass spectrometry,laser ablation multi-collector inductively coupled plasma mass spectrometry,electron probe microanalysis and isotope dilution-thermal ionization mass spectrometry.New methods of U-Pb isotopic dating for uranium minerals,however,should be tested and established in order to acquire accurate formation time for rocks and minerals from sandstonetype uranium deposit.Such knowledge is important for a comprehensive and accurate understanding of the formation and evolutionary history of the sandstone-type uranium deposit and for developing a new mineralization theory for sandstone-type uranium deposit.The new isotopic dating methodology will also have a broad application in uranium geological exploration.
