Mineral spectra acquired using handheld LIBS - part 1

These datasets consist of pure mineral spectra acquired using a handheld LIBS analyzer. Mineral samples of various species, including silicates, carbonates, oxides, sulfides, and native elements, were analyzed between 2021 and 2023 as part of three research projects: NEXT project, Labex Ressources 21, and ARTeMIS ERASMUS+ project. The accompanying metadata file includes details such as sample ID, mineral type, chemical formula, sourcing location, sample type, matrix, analysis points, number of spectra obtained, and acquisition parameters. Given the large number of files, the database has been published in four parts.
