本文介绍了用激光烧蚀电感耦合等离子体质谱法直接分析岩石的方法。对标准岩粉和原岩粉进行了分析，尽管表面状态不同，但分析结果一致。用聚焦激光束直接对JG-1花岗岩中的黑云母进行了微探针分析，所得结果与用从原岩中分离出的黑云母的常规水溶液法所给出的溶液值非常接近。对于定量分析，测量的信号强度通过消融重量或钡信号强度标准化。成功地测定了日本地质调查所火成岩系列12个标准岩石中的42个主、次元素（其中2个作为内标）。
Direct analysis of rocks by laser ablation inductively coupled plasma mass spectrometry is described. Both powdered standard rocks and the original rocks were analysed and the results agreed with each other in spite of the difference in the surface states. Microprobe analysis of biotite in granite JG1 was also done directly with a focused laser beam and the results obtained were very close to the solution values given by the conventional aqueous method using biotite separated from an original rock. For quantitative analysis, the measured signal intensity was normalized either by the ablated weight or the barium signal intensity. Forty-two major and minor elements (two of them being used as internal standards) in twelve standard rocks fromt the igneous rock series of the Geological Survey of Japan were determined successfully.
