34.人工石炭および天然石炭のバイオマーカー分析による石炭起源物質の推定

抄録

The biomaker analysis of coals from Japan, China and Indonesia were carried out for the estimation of original materials of coal. Also extractable organic matters from resent plant materials which heated with water were analyzed their biomakers to compare with that of coals. The n-alkane distribution of coals shows that low molecular weight compounds are increased with maturation degree increasing. But on artificial coal made from Metasquoia leafs is not indicated like the phenomena of coals. The diterpenoid whch is originated from coniferous woods is rich in several Japanese coal, but not found in Indonesian coals. The hopanoid distributions between two coals which are constists of low H/C atomic ratio and high H/C atomic ratio from the same seam are not show their distinction. The characteristics of coals which affected with characters of original materials are not valid for Hopanoid distribution.
