建立了一种利用激光探针等离子体质谱技术同时原位测定锆石Ｐｂ－ Ｐｂ 及Ｐｂ － Ｕ 年龄和２５ 个微量元素的快速分析方法。Ｐ 的检出限为１４ μｇ／ｇ ，Ｓｃ 的检出限为３ μｇ／ ｇ，Ｒｂ、Ｎｂ、Ｂａ 及稀土元素Ｎｄ 、Ｇｄ 、Ｄｙ、Ｅｒ 及Ｙｂ 的检出限为０ ．１ ～０ ．３ μｇ／ｇ ，Ｐｂ 的检出限０ ．５ μｇ／ｇ ，其它稀土元素及Ｓｒ、Ｙ、Ｈｆ 、Ｔａ 、Ｔｈ 和Ｕ 的检出限为１０ ～９０ ｎｇ／ ｇ 。方法对绝大多数微量元素的相对标准偏差为５ ％ ～１５ ％ ；２０７Ｐｂ／２０６Ｐｂ 比值的测量精度为１ ％ ～３ ％ ，２０６Ｐｂ／２３８ Ｕ 比值的测量精度为２ ％～１０ ％ 。
A rapid method for the simultaneous determination of zircon Pb-Pb and Pb-U ages and 25 trace elements using laser probe-based plasma mass spectrometry was established. The detection limit of P was 14 μg / g, the detection limit of Sc was 3 μg / g, and the detection limit of Rb, Nb, Ba and rare earth elements Nd, Gd, Dy, Er and Yb was zero. 1 ~ 0. 3 μg / g, the detection limit of Pb 0. 5 μg / g. The detection limits of other rare earth elements and Sr, Y, Hf, Ta, Th and U were 10-90 ng / g. The relative standard deviation (RSD) of the method for most trace elements is 5% -15%, the measurement accuracy of 207Pb / 206Pb is 1% -3%, and the measurement accuracy of 206Pb / 238 U is 2% -10%.
