英文摘要 | The accurate and precise ages of uranium mineralization are scarce because those uranium minerals (pitchblendes) usually show heterogeneous and fine grains in component and structure, and may have formed in several stages. The conventional bulk uranium minerals (pitchblendes) U-Pb dating methods previously employed were unable to avoid alteration minerals and precisely discriminate different stages of uranium mineralization to obtain the precise ore-forming ages. With the constant improvement and development of analytical techniques, ore-forming age of uranium mineralization has been extensively studied. However, the insufficient understanding on constraint for uranium mineral U-Pb dating techniques, and uranium mineral requirement for U-Pb dating systems commonly resulted in that either the obtained ages were geological meaningless or the isochron ages were failure to be constructed. This paper presents the development process of analysis methods for ore-forming ages of uranium mineralization in detail. These main dating methods include: (1) uranium mineral U-Th-tota Pb chemical age; (2) uranium mineral U-Pb model age; (3) conventional uranium mineral U-Pb isochron age; (4) uranium mineral associated with other minerals dating; and (5) in-situ uranium mineral U-Pb dating. Additionally, we also review these issues on various dating techniques of uranium mineralization and propose some items for future development of metallogenic geochronology on uranium deposit |
