英文摘要Apatite, an important mineral widely distributed in various geological environments, can be used for in situ U-Pb dating and Sr-Nd isotope analyses. The LA-ICPMS U-Pb dating and Sr-Nd isotopic determinations require suitable matrix-matched reference materials. Current apatite standards are rare and have some defects. Most natural apatite references display high and variable common Pb, which may be the most difficult issue in microbeam determination. We provided a gem-quality apatite MAP-3, subjected to detailed major- and trace element composition, U-Pb dating, and Sr-Nd isotopic analyses to assess its homogeneity of chemical composition and suitability as a reference material for microbeam U-Pb dating and Nd isotope analyses. Through comprehensive analyses, we show that the MAP-3 apatite is free of mineral inclusions and is uniform at the level of analytical precision of major- and trace element, U-Pb isotopic, and Nd isotopic ratios despite compositional zones from CL images. The MAP-3 apatite has ID-TIMS determined mean isotopic ratio values of 0.13222 +/- 0.00016 for (PbU)-Pb-206-U-/238, 1.2084 +/- 0.0030 for (PbU)-Pb-207-U-/235, and 0.0663 +/- 0.0001 for (PbPb)-Pb-207-Pb-/206 and the weighted mean (PbU)-Pb-206-U-/238 ages of 800.5 +/- 0.9 Ma (2 s, MSWD = 1.5, n = 11). The Nd-143/Nd-144 isotopic results determined by (ID)-TIMS are 0.511248 +/- 0.000006 (2 s, MSWD = 4.2, n = 11) with moderate Nd contents of similar to 1532 ppm. U-Pb age and Nd isotopic compositions obtained by LA-(Q, SF-SC, MC)-ICPMS analysis are reproducible and agree with the values of TIMS, which indicates that MAP-3 apatite has the potential to be a primary reference material for microbeam determination of U-Pb ages and Nd isotope analyses. To validate the effectiveness of the potential, we dated some apatite reference materials of known age and two geological apatites. The results demonstrated the high-quality U-Pb dating reference materials used with MAP-3 apatite.
