英文摘要We present an analytical protocol for in situ U-Pb isotope dating of wolframite series minerals [(Fe,Mn) WO4], the main ore mineral for tungsten, by LA-SF-ICP-MS. Precision and accuracy of the protocol was intensively assessed using our newly developed well-characterized U-Pb wolframite reference material. The tungsten oxide interference on Hg and Pb was investigated in detail. The matrix effect between ferberite and hubnerite during laser ablation was thoroughly examined for wolframite series minerals with a different Mn/(Mn + Fe) ratio. The closure temperature of wolframite, with respect to the U-Pb system, was evaluated. The application of eleven wolframite samples, with ages from similar to 1780 Ma to similar to 26 Ma, robustly demonstrated the feasibility of our approach. Most studied wolframite series minerals yielded U-Pb concordant or subconcordant ages. Samples with a relatively high U content and negligible common Pb content typically had a Pb-206/U-238 age precision of ca. 1%. The new in situ data agree well with published cassiterite or wolframite ages from the same locations. LA-SF-ICP-MS, with the advantages of high sensitivity, rapidity, and relatively low cost, as well as moderate spatial resolution (i.e., 32 or 44 mm) that is sufficiently high to avoid sulfide inclusions, is the method of choice for in situ wolframite U-Pb microanalysis.
