| In Situ U-Pb Dating of Apatite Using LA-MC-ICP-MS |
| A new in situ U-Pb dating method for apatite using LA-MC-ICP-MS has been established, and the experimental process is described in this paper. 5 apatite U-Pb dating results determined by the new method and verified by ID-TIMS method are reported in this paper, with the data obtained being standard qpatite SDG, (1596±15) Ma (MSWD=1.5, n=7, LA-MC-ICP-MS), (1602±13) Ma (n=5, MSWD=0.578, ID-TIMS); apatite samples from an iron deposit, (125±14) Ma (n=25), (124.2±3.5) Ma (MSWD=1.5, n=37); apatite from gneissic rocks in the Altun Mountains of Xinjiang, (250.8±3.9) Ma (MSWD=8.6, n=26), (245.4±2.9) Ma (MSWD=2.1, n=39). |
