Abstract
The oils from the Kuqa Depression are easily distinguished from the other two families due to their terrigenous origin. The major characteristics of the Kuqa oils are high Pr/Ph ratio, very low DBT/P ratio, heavy bulk isotopic composition, low PAH alkylation degree, high proportion of C20 and C21 tricyclic terpanes and C24 tetracylic terpane, and abundance of triaromatic dinosteranes and 4-methyl-24-ethyltriaromatic cholestanes. These characteristics are consistent with terrestrial organic source rocks deposited under sub-oxic conditions.
