文摘

Peat-forming vegetation is characterized by abundant decay of gymnosperm plants. Activity of methanotrophic-, chemoautotrophic- and heterotrophic bacteria was noticed. Prominent C28 28,30-bisnorneohop-13(18)-ene was firstly reported in the lignite extracts. C28 28,30-bisnorneohop-13(18)-ene could be an important precursor of orphan aromatic hopanoids. Petrographic and biomarker parameters reflect well palaeoclimate variations.
