Abstrakt

Sanidine 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% NaAlSi3O8 molecules. The sanidine composition is very individual for many beds and can be used successfully for correlations.
