文摘Retene and methylretene have been identified by gas chromatography-mass spec-trometry in aromatic hydrocarbon fractions of Silurian carbonate extracts of the Michigan Basin. Retene identified in pre-Devonian carbonates indicates that the compound not only is the biomarker of higher plants but also derived from alga or bacterium. The geochemical significance of methylretene has been discussed.
