Abstract

The Mn2+ EPR spectra of 12 marbles and limestones (calcitic, dolomitic and calci-dolomitic) collected from different Greek quarries have been analysed by means of cluster analyses numerical taxonomy. By means of Mn2+ EPR line shape this technique allowed classifying all samples in concordance with their mineralogical structure. Accordingly, we have found that while Euclidean and power distances showed to be more adequate in differentiating samples belonging to the same petrologic group, the Perason’s correlation coefficient is most suitable to discriminate samples having different mineralogical composition..
