Abstract
The structure-sensitive and standardless phase quantification method based on a Rietveld analysis of X-ray powder diffraction data was compared to some traditional techniques. It was found that the Rietveld-based method is at least equal, in several cases superior to the R1R technique, and can be a fast and simple substitute for the optical modal analysis. At the same time it is shown that the points of a Rietveldbased rock classification, using the QAP rock classification of Streckeisen, can be erroneously shifted on the diagram towards the higher plagioclase containing types due to the pcrthitic exsolution of K-feldspar and consequent inherent overestimation of the abundance of plagioclase.
