ResumoSanidine composition of 130 samples of bentonites from 12 sections of Telychian (some possibly Sheinwoodian) age was analysed by X-ray diffractometry for correlation purposes.Solid solution of magmatic sanidine contained 20-47% NaAlSi 3 O 8 molecules.The sanidine composition is very individual for many beds and can be used successfully for correlations.
