Carbon isotope fractionation by photosynthesis of higher land plant is mainly controlled by the growth rate of plants, which is partly related to partial pressure of atmospheric carbon dioxide. Compound specific stable carbon isotope ratio of higher plant biomarkers in the terrigenous sedimentary rocks can be one of parameters for estimation of paleo-patial pressure of atmospheric carbon dioxide. The variation of stable carbon isotope ratio of higher plant biomarkers in the Tertiary non-marine organic-rich sedimentary rocks such as coal and coaly mudstones in Japan and Sakhalin were investigated in the present study. The following results were consequently obtained.(1) Tertiary non-marine terrigenous sedimentary rocks commonly contain diterpanes and aromatic diterpenoids such as diaromatic totarane and retene.(2) Abundance of retene is positively correlated to that of abietane type diterpenoid aromatic hydrocarbons, suggesting their genetic relationship.(3) Abundance of retene and abie … More tane type compounds is negatively correlated to that of oleanane which is derived from angiosperms, suggesting that retene is mainly derived from gymnosperm.(4) Abundance of dibenzofuran is positively correlated to that of oleanane, suggesting that dibenzofuran is also derived from angiosperms.(5) Carbon isotope ratios of n-alkanes tend to decrease with increasing carbon numbers of n-alkane, showing higher molecular weight n-alkanes are mainly derived from higher land plants.(6) Carbon isotope ratios of n-alkanes, β-norisopimarane, diaromatic totarane, and retene in Eocene coal and coaly mudstones are enriched in ^<13>C compared to those of Miocene coal and coaly mudstones.(7) High-pressure liquid chromatography is useful method for aromatic hydrocarbon fractionation for gas chromatography combustion isotope ratio mass spectrometry.(8) Variation of carbon isotope ratio of higher plant biomarker with geologic age is consistent with the possible geologic change of atmospheric carbon dioxide partial pressure.Compound specific stable carbon isotope ratio of higher plant biomarkers can be a useful parameter to estimate the atmospheric pCO_2 in the geologic time. However, other environmental condition, which affect growth rate of higher plant, may be influential to the isotope ratio of higher plant biomarkers. Less

高等陆生植物光合作用的碳同位素分馏主要受植物生长速率控制，而植物生长速率又与大气二氧化碳分压有关。陆源沉积岩中高等植物生物标志物的复合比稳定碳同位素比值可作为估算大气二氧化碳古分压的参数之一。本文研究了日本和库页岛第三系非海相富有机质沉积岩（煤和煤质泥岩）中高等植物生物标志物稳定碳同位素比值的变化。结果如下：(1)第三系非海相陆源沉积岩中普遍含有二萜和芳香二萜，如二芳烷和油烯。(2)网烯的丰度与阿比烷型二萜芳烃的丰度呈正相关，表明二者存在亲缘关系。(3) retene和abie . More tane型化合物的丰度与来自被子植物的齐烷烷的丰度呈负相关，表明retene主要来自裸子植物。(4)二苯并呋喃的丰度与齐墩烷的丰度呈正相关，表明二苯并呋喃也来源于被子植物。(5)随着正构烷烃碳数的增加，正构烷烃碳同位素比值呈下降趋势，表明高分子量正构烷烃主要来源于高等陆生植物。(6)始新世煤和煤质泥岩中正构烷烃、β-异辛烷、二芳烷和稀土烃的碳同位素比值比中新世煤和煤质泥岩富集于^<13>C。(7)高压液相色谱法是气相色谱燃烧同位素比质谱法分离芳烃的有效方法。(8)高等植物生物标志物碳同位素比值随地质年代的变化与大气二氧化碳分压可能的地质变化相一致。高等植物生物标志物的复合比稳定碳同位素比值可作为估算地质年代大气pCO_2的有用参数。然而，其他影响高等植物生长速率的环境条件可能会影响高等植物生物标志物的同位素比值。少
