Diterpenoid hydrocarbons consists mainly of kaurenes and are indicati ve of higher plant contributions, specially from conifer resins. Triterpenoids consist mainnly of 17beta(H),21beta{H)-hopanes derived from recent biogenic activity which indicates the geological immaturity of this lignite and implies that it has undergone only a mild thermal history. Sterols consist of cholesterol, carmpesterol, stigmasterol and beta-sitosterol and their distribution suggests a possible phytoplankton input, which should confirm the geological hypothesis that this sediment had an estuarine or deltaic origin. Occurrence of stanones with the biological 5alfa configuration was also observed.Peer reviewedElsevier201320131991info:eu-repo/semantics/otherhttp://purl.org/coar/resource_type/c_3248info:eu-repo/semantics/bookParthttp://hdl.handle.net/10261/71735reponame:DIGITAL.CSIC.
