4M method – new application of Mössbauer spectroscopy to classification of meteorites. How it works?

Abstract4M method is a new application of Mössbauer spectroscopy to quantitative classification of ordinary chondrites. 4M derives from four words: meteorites, Mössbauer spectroscopy, multidimensional discriminant analysis, Mahalanobis distance. This method was published by us in 2019. In this paper we present application of 4M method to classification of four meteorites. Link to script with calculation needed for classification of ordinary chondrites was given.

Identification and classification of meteorites using a handheld LIBS instrument coupled with a fuzzy logic-based method

A handheld laser-induced breakdown spectroscopy (LIBS) instrument associated to a fuzzy logic-based method is proposed as a novel tool that is able to provide information on the nature of meteorites and discriminate among iron, stone, stony-iron meteorites and meteorwrongs.
