Zircon is a robust dating accessory mineral, and often develop thin ring (generally less than 5 μm), which poses challenges to obtaining accurate ages of this ring. This article conducted a series of comparative and experimental studies from three aspects: ① sample preparation methods; ② experimental conditions, and ③ data algorithms to evaluate the reliability of multi-pulse short time ablation method for LA-ICP-MS U-Pb dating of ultra-thin ring (~1 μm) in natural zircons. The results showed that although the double-sided adhesive sample preparation method is fast, the sample observation under microscopic and laser system are poor. The resin-fixed preparation method has high efficiency, is easy to observe with transmitted light and reflected light, and is conducive to sample surface focusing. For laser setting parameters, data results in 5 Hz/2 s ablation are more stable than those in 10 Hz/1s ablation. The peak integration method is superior to linear regression and mean value methods for data reduction. Our results show that by using rapid erosion method for Pleovice and Qinghu zircon dating are consistent with the recommended values within the error range, but the data error is relatively large (~5%, 1σ). The zircon standards Pleovice and Qinghu are improved by 3% and 2% respectively when the 50%~60% of each signal peak value peak integration method was used. The combination of resin-fixed sample preparation, peak integration data processing method and multi-pulse short time ablation method can get an acceptable age of ultra-thin zircon ring. This method can provide more age constraints for multi-age geological processes.
