英文摘要: ln the present paper, eight core samples of cyanobacterial dolostone from the Dengying Formation (Sinian ) of the Weiyuan Gas Field, Sichuan,southwest China,have been studied organically and geochemically,It has been shown that the following biomarker compouds exist.C12-C37 n-alkanes,which have an even-carbon-numbered predominance of n-alkanes with a major constituent of n-C~6 or C~s, and a less-than-one value of Pr/Ph; C29 tricyclic diterpanes; C27~35 hopanes and gammacerene in high abundance; steranes with C29 as the predominating component; C~2~C30 alkyl cyclohexanes; naphthalenes; phenanthrenes; diphenyls; pyrene; triaromatic steranes and alkylbenzenes with a long branched alkyl chain; in aromatic fraction, of which naphthalenes and phenanthrenes are the major compounds. It is strongly suggested that these biomarkers were derived from micropalaeoplants and algae, and that they are important environmental indicators.
