摘　　要：Steroid hydrocarbons, mainly derived from sterol precursors in the cell membrane of eucaryote such as algae and high plants, are widespread in. various fossil fuels and sediments. Among steroids, dinosteranes, i.e. 4,23,24-trimethylcholestane and its homologues, are more attractive for their specific side-chain on the molecular skeleton and their special source significance. Summons et al. (1987) found that the Triassic-Early Cretaceous immature marine source rocks and oils show high concentration of 4α-methyl
