Allanite is a REE-rich accessory mineral commonly enriched in Th and U and is therefore well suited to U-Th-Pb geochronology. However, widely used international allanite reference materials typically contain common Pb and are not readily accessible. Zircon reference materials are robust, available, and have been applied to allanite age determination via non-matrix-matched LA-ICP-MS calibration, but their performance requires further evaluation. In this study, we provide radiometric ages for magmatic allanite from two Cretaceous granite plutons (Wanganzhen, sample 10581-1 and Heigoubei, sample 10426-1) in the northern Taihang Orogen, China, using zircon reference materials 91500 and Plešovice as primary standards and for quality control. Petrography and trace-element signatures indicate negligible hydrothermal alteration. Tera-Wasserburg lower-intercept ages for allanite sample 10581-1 range from 128.0 ± 4.9 Ma (24 μm spot size) to 135.0 ± 3.0 Ma (60 μm), and for sample 10426-1 from 110.0 ± 22.6 Ma (24 μm) to 108.9 ± 9.9 Ma (60 μm). Plešovice-calibrated results are comparable (123.9 ± 5.4 to 131.9 ± 4.0 Ma; 100.0 ± 28 to 113.0 ± 15 Ma). All allanite ages overlap within uncertainty with coeval zircon U-Pb ages (132.0 ± 0.8 Ma and 110.3 ± 0.8 Ma). Although Th-Pb ages decouple from U-Pb ages at 24 and 44 μm, probably due to different fractionation behaviours between zircon and allanite, the overall results demonstrate that zircon 91500 and Plešovice are suitable reference materials for allanite U-Th-Pb age determination. A spot size of 32–44 μm is recommended. This study provides validation for the non-matrix-matched U-Th-Pb age determination method of allanite using zircon standards, thereby expanding the applicability of allanite geochronology.
