Abstract
Two Turkish oil shales were extracted at room temperature with N-methy lpyrrolidone and with a mixture of N-methylpyrrolidone and carbon disu lfide. The extracts were analysed by chromatography and spectroscopy. The aromatic compounds contained small clusters of aromatic rings high ly substituted with branched alkyl groups. The alkane geomarkers are c onsistent with immature sediments derived from terrestrial higher plan ts and aquatic material deposited under saline conditions. (C) 1997 El sevier Science Ltd.
