FTIR,XRF and Powder XRD Experimental Study of Charoite:Crystal Chemical Features of Two Associated Generations

摘要

A collection sample of charoite rock from the Murun massif(Russia)was examined.Based on the textural and structural features,it was concluded that the sample comprised two charoite generations:the earliest one,so-called"block",and the second one,"schistose-goffered".A small amount(1-2 g)of each phase was used for sequential X-ray diffraction,X-ray fluorescence and FTIR absorption analyses.The obtained results allowed us to reveal some crystal chemical features of the early and later generations of the charoite specimen under study.
