Abstract The review focuses on the most relevant advances and is reported in different sections relative to the analyzed objects (identification of rocks/minerals and sourcing; resources applications; slurry and drill cores; rare earth elements; light elements). Special sections report on the good practices for Laser Induced Breakdown Spectroscopy (LIBS) analysis and the most critical points that should be checked in order to validate any LIBS analysis on most common geological purposes. LIBS gives access to the most relevant elements in geosciences/geology and the typical detection limits fit usual requirements, with the advantage of permitting faster analyses than the other techniques classically used. Whether considering the case of metals of economic interest, that of critical elements, or that of light elements, LIBS has definitely been proved an adequate tool, and there is no need to do more on its evaluation in this field of application. Considering that LIBS measurements require limited sample pre-treatment, and considering also that LIBS is a fast all-optical multi-elemental technique, it is undoubtedly the optimal way to achieve a first quick screening and then provide valuable data prior to any further laboratory analyses. Therefore, the recent development of LIBS imaging should quickly lead to the implementation of LIBS imaging systems in the analytical laboratories worldwide in charge of analyzing geological samples.

用于地质的激光诱导击穿光谱分析的进展：批判性评论

摘要 该评论侧重于最相关的进展，并在与分析对象（岩石/矿物的识别和来源；资源应用；泥浆和钻芯；稀土元素；轻元素）相关的不同部分进行报告。特殊部分报告了激光诱导击穿光谱 (LIBS) 分析的良好实践以及应检查的最关键点，以验证最常见地质目的的任何 LIBS 分析。LIBS 可以访问地球科学/地质学中最相关的元素，典型的检测限符合通常的要求，其优点是比其他经典使用的技术分析速度更快。无论是考虑具有经济利益的金属、关键元素还是轻元素，LIBS 已经被证明是一个足够的工具，在这个应用领域不需要做更多的评估。考虑到 LIBS 测量需要有限的样品预处理，而且考虑到 LIBS 是一种快速的全光学多元素技术，它无疑是实现第一次快速筛选，然后在任何进一步实验室分析之前提供有价值数据的最佳方式. 因此，LIBS 成像的最新发展应该会迅速导致 LIBS 成像系统在全球负责分析地质样品的分析实验室中的实施。考虑到 LIBS 是一种快速的全光学多元素技术，它无疑是实现第一次快速筛选，然后在任何进一步实验室分析之前提供有价值数据的最佳方式。因此，LIBS 成像的最新发展应该会迅速导致 LIBS 成像系统在全球负责分析地质样品的分析实验室中的实施。考虑到 LIBS 是一种快速的全光学多元素技术，它无疑是实现第一次快速筛选，然后在任何进一步实验室分析之前提供有价值数据的最佳方式。因此，LIBS 成像的最新发展应该会迅速导致 LIBS 成像系统在全球负责分析地质样品的分析实验室中的实施。
