The spectral areas of the different mineralogical phases found by Mössbauer spectroscopy in meteorites are proportional to the number of iron atoms in this mineralogical phase. This property of Mössbauer spectra can be the basis for constructing a method for the classification of ordinary chondrites. This idea was first explored at the Mössbauer Laboratory in Kanpur. This group suggested a qualitative method based on 2‐dimensional plots of Mössbauer spectral areas and thus classified properly some meteorites. We constructed a quantitative method using [https://en.wikipedia.org/wiki/Mössbauer_spectroscopy '''M'''össbauer spectral areas], [https://pl.wikipedia.org/wiki/Analiza_dyskryminacyjna '''m'''ultidimensional discriminant analysis], and [https://pl.wikipedia.org/wiki/Odległość_Mahalanobisa '''M'''ahalanobis distance] ('''4M method''') to determine the probability of a [https://en.wikipedia.org/wiki/Ordinary_chondrite '''m'''eteorite] to be of type H, L, or LL. Based on 59 Mössbauer spectra, we calculated by the 4M method, '''S<sub>cluster</sub>''', the ''level of similarity'' of the {{Link-MBD|code=34019|name=Goronyo}} meteorite to the clusters. On the plot of ferrosilite versus fayalite, the point representing Goronyo is located on the border between H and L areas. Calculated by the 4M method, the meteorite Goronyo is 32% similar to type H, 75% to type L, and 11% to type LL. Additional mineralogical analyses suggested that the Goronyo meteorite would be classified as type L, although it was originally reported as type H in the Meteoritical Bulletin Database;<br />patrz → [[Acta Soc.
