Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) enables spatially resolved quantitative measurements of major, minor and trace element abundances in igneous rocks and minerals with equal or better precision than many other in situ techniques, and more rapidly than labour-intensive wet chemistry procedures. Common applications for LA-ICP-MS in the Earth sciences centre on investigating the composition of natural and experimental geological materials, including: analysis of whole rock silicate glasses, flux-free pressed powder tablets and/or fused aliquots of materials; in situ probing of individual minerals, xenocrysts, fluid and melt inclusions, experimental run products, and siderophile-rich micronuggets; and multidimensional chemical mapping of complex (multiphase) materials.
激光烧蚀电感耦合等离子体质谱法（LA-ICP-MS）能够对火成岩和矿物中的主要、次要和微量元素丰度进行空间分辨定量测量，其精度与许多其他原位技术相当或更高，且比劳动强度大的湿化学方法更快。LA-ICP-MS在地球科学中的常见应用集中于研究天然和实验地质材料的成分，包括：分析全岩硅酸盐玻璃、无助熔剂压制粉末片和/或材料的熔融等分试样；对单个矿物、捕虏晶、流体和熔体包裹体、实验产物以及富亲铁微块进行原位探测；以及对复杂（多相）材料进行多维化学绘图。
