| Abstract: |
| The principal factor analysis indicates that short chains nC16, nC17.nC18 and nC19 have relatively large positive charge, while long chains nC27 and nC29 have relatively large negative charge.On the third principal factor axis, the carbon with positive charge is almost even carbon, while the carbon with negative charge is almost odd carbon.The parameters of biomarker compounds are divided into 3 groups; (I) nC31l/nC17,nC27/nC17, nC27/T and Pr/Ph recognizing the input of source material; (2) nC27/T, Ph/nC18, CPI and Pr/Ph showing oxidation and reduction of depositional environment; (3) Tm/Ts, Ph/nC18 indicating the maturity of sedimentary organic matter. |
