Improving spatially-resolved lithium quantification in drill core samples of spodumene pegmatite by using laser-induced breakdown spectroscopy and pixel-matched reference areas

Ultrafast μLIBS imaging for the multiscale mineralogical characterization of pegmatite rocks

“…29 In a parallel approach to drill core analysis, the authors employed a multivariate method, utilizing extensive training data through pixel-matched reference maps obtained via LA-ICP-TOFMS. 30 By combining LA-ICP-TOFMS and LIBS, the authors achieved rapid and precise spatial quantification of Li 2 O and other major rock-forming elements in centimetric areas of a Li-bearing pegmatite drill core. However, the used spatial resolution of approximately 200 μm limits the identification of small mineral phases, a limitation overcome by μLIBS imaging as deployed in this study.…”

Quantification of lithium using handheld instruments: application of LIBS and XRF spectroscopy to assay the lithium content of mineral processing products

“…However, using in situ "micro" destructive methods, such as laser induced breakdown spectroscopy (LIBS) and laser ablation coupled to mass spectroscopy (LA-ICP-MS) allow the detection and quantication of Li. [24][25][26][27][28][29] As lithium can be easily detected by LIBS, portable LIBSs are more and more used for its direct quantication in raw material. [30][31][32] However, the models found in the literature mainly consist of qualitative or quantitative detection of lithium in Li-bearing minerals or in rock samples for exploration purposes.…”
