摘要
文章论述了U-Pb同位素在砂岩型铀矿成矿作用研究中的示踪作用,其内容包括砂岩型铀矿的成矿年龄、沉积砂体和蚀源区岩石的原始铀含量(U0)及铀的变化系数(△U)等;同时列举了该技术手段在部分砂岩型铀矿床中的实际应用。结果表明,U-Pb同位素示踪技术在砂岩型铀矿成矿预测和成矿机理研究方面能够发挥重要的作用。
This paper discussed the mineralization o{ in - situ leachable sandstone type uranium deposit with U- Pb isotope tracing technology., dating the metallogenic age of sandstone type uranium deposit, deriving the initial uranium content （U0） and uranium variation coefficient （△U） of the host sandbody and provenance rocks, some application cases were also enumerated on tracing sandstone type uranium deposit. This result shew that the U - Pb isotope tracing technique could play an significant role in the study of metallogenic mechanizm and metallogenic forecast for in - situ leachable sandstone type uranium deposit.
