Popis:	R-mode technique factor analysis, performed on as many as 186 garnet and 103 omphacite samples from eclogites of known geological setting, confirms the three-group partition given by Smulikowski (1964, 1965) and Coleman et al. (1965), and lends support to the interpretation of eclogites as rocks formed under a wide range of P-T conditions both in the metamorphic and in the igneous realm.
