| 英文摘要 | As a robust proxy, molybdenite has been widely applied to determination of re-os age. this study simplified the chemical separation of re and os using concentrated hno(3) for digestion of molybdenite based on the negligible level of common os relative to in genetic (187)os in molybdenite, a common os standard was used as spike, and as a result, os isotopic mass fractionation during icp-ms measurements could be on-line corrected. improving the quality of analytical data this method was validated using national certified molybdenite standards, and the results were well consistent with the certified values. using this method for determination of molybdemte sampled from xingping skarn-type mo deposit, liangyang granite composite, reasonable re-os age data have been obtained in practice, it is suggested to use enough amounts of molyhdemte, which should be homogenized fine-grain in order to obtain representative re-os age |
