Here, the potential of laser-induced breakdown spectroscopy (LIBS) in grading calcareous rocks for the lime industry was investigated.In particular, we developed a system equipped with non-intensified detectors operating in scanning mode, defined a suitable data acquisition protocol, and implemented quantitative data processing using both partial least squares regression (PLS-R) and a underwater treasures sunken medallion multilayer perceptron (MLP) neural network.Tests were carried out on 32 samples collected in various limestone quarries, which were preliminarily analyzed using traditional laboratory X-ray fluorescence (XRF); then, they were divided into two groups for calibration and validation.

Particular attention was dedicated to the development of LIBS methodology providing a reliable basis for precise material grading.The congruence of the results achieved demonstrates the capability of the present approach to precisely quantify major and minor geochemical components of calcareous google pixel 7 freedom rocks, thus disclosing a concrete application perspective within the lime industry production chain.
