将掺钕的钇铝榴石（Ｎｄ：ＹＡＧ）激光器与高精密ＭＭ１２００质谱计、电子倍增器联网，应用连续激光质谱对单颗粒矿物、光片样品进行微区４０Ａｒ／３９Ａｒ测年、坪年龄和等时线年龄研究。在光片上测定南极乔治王岛北海岸玄武岩等时线年龄（５２．３８±１．０５）Ｍａ和贵州绿豆岩年龄（２３９．１６±１４．１３）Ｍａ，两者与实际地质背景吻合。对两个中生代和太古代单颗粒黑云母进行连续激光质谱阶段升温４０Ａｒ／３９Ａｒ坪年龄谱测定，获得与常规法相一致的坪年龄谱
The neodymium-doped yttrium aluminum garnet (Nd: YAG) laser was connected with a high-precision MM1200 mass spectrometer and an electron multiplier. Continuous laser mass spectrometry was used to measure the 40Ar / 39Ar dating, plateau age and Isochord age study. The isochron age (52.38 ± 1.05 Ma) and the Guizhou mungbean age (239.16 ± 14.13 Ma) of the North Coastal island of King George Island in Antarctica were measured by light and coincided with the actual geological background. The 40Ar / 39Ar plate ages of two Mesozoic and Archean monbacite biotites were measured by continuous laser mass spectrometry and the plateau age spectrum was obtained in accordance with the conventional method
