Detrital zircon (DZ) U‐Pb laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) has revolutionised the way geologists approach many Earth science questions. Although recent research has focused on rapid sample throughput, acquisition rates are limited to 100–300 analyses h⁻¹. We present a method to acquire zircon U‐Pb dates at rates of 120, 300, 600 and 1200 analyses h⁻¹ (30, 12, 6 and 3 s per analysis) by multi‐collector LA‐ICP‐MS. We demonstrate the efficacy of this method by analysing twelve zircon reference materials with dates from ~ 3465 to ~ 28 Ma. Mean offset from high‐precision dates increases with faster rates from 0.9% to 1.1%; mean random 1s uncertainty increases from 0.6% to 1.3%. We tested this new method on a sandstone sample previously characterised by large‐n DZ geochronology. Quantitative comparison shows increased correspondence among age distributions comprising > 300 dates. This new method holds promise for DZ geochronology because (a) it requires no major changes to hardware, but rather modifications to software; (b) it yields robust age distributions well‐suited for quantitative analysis and maximum depositional age calculations; (c) there is only a minor sacrifice of accuracy and measurement uncertainty; and (d) there is less burden to researchers in terms of time investment and analytical cost.

激光烧蚀多收集器ICP-MS进行快速U-Pb年代学

碎屑锆石（DZ）U‐Pb激光烧蚀电感耦合等离子体质谱法（LA‐ICP‐MS）彻底改变了地质学家解决许多地球科学问题的方式。尽管最近的研究集中在快速样品通量上，但采集速率仅限于100–300 h ^-1分析。我们提出了一种通过多收集器LA‐ICP‐MS以120、300、600和1200分析h ^-1（每次分析30、12、6和3 s）的速率获取锆石U-Pb数据的方法。我们通过分析日期从〜3465到〜28 Ma的十二种锆石参考材料证明了该方法的有效性。高精度日期的平均偏移量以更快的速度从0.9％增加到1.1％；平均随机1秒不确定性从0.6％增加到1.3％。我们测试了对先前的特征在于large-砂岩样品这种新方法Ñ DZ年代学。定量比较显示，包含> 300个日期的年龄分布之间的对应关系增加。这种新方法为DZ年代学提供了希望，因为（a）它不需要对硬件进行重大更改，而需要对软件进行修改；（b）得出的年龄分布稳定可靠，非常适合进行定量分析和最大沉积年龄计算；（c）在准确性和测量不确定性方面仅作了很小的牺牲；（d）在时间投资和分析成本方面，减轻了研究人员的负担。
