摘要:
Biomarker hydrocarbons, such as C16-C31 n-alkanes, C19, C20, C22 isoprenoids, C14-C26 dicyclic and tricyclic terpanes, C27-C33 pentacyclic triterpanes, C27-C29 n-steranes, rearranged steranes and C19-norpregnane, have been identified as being present in Fu-shun Bituminous Coal by GC/MS. The carbon distribution of these biomarker hydrocarbons and the ratio of steranes and terpanes with different stereo-configuration show that although metamorphism of Fu-shun bituminous coal has progressed to higher rank coalification stage, it is still a relatively young bituminous coal. Moreover, it has amounts of resin and is a humus continental deposit formed by higher plants, which is consistent with the results obtained by routine coal analysis and coal petrography. This method of organic geochemical analysis provides significant information about coal genesis, coal maturation and its depositional environment.
