Abstract Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) mapping is a rapidly expanding field in the geosciences because of the wealth of spatial information it provides on the petrogenesis of igneous, metamorphic and sedimentary rocks and ore mineral formation. The technique has also opened many new applications in forensics, archaeology and the imaging of trace metals in biological tissues. Instrumentation advances in both LA and ICP-MS systems now permit precise isotopic analysis with laser spot sizes of

地学中的 LA-ICP-MS 成像及其在地质年代学中的应用

摘要 激光烧蚀电感耦合等离子体质谱 (LA-ICP-MS) 绘图是地球科学中一个迅速扩展的领域，因为它提供了关于火成岩、变质岩和沉积岩的岩石成因以及矿石矿物形成的丰富空间信息。该技术还在法医学、考古学和生物组织中痕量金属成像方面开辟了许多新应用。LA 和 ICP-MS 系统的仪器进步现在允许使用激光光斑尺寸进行精确的同位素分析
