A comprehensive study of lipid biomarkers on a sediment core from the Amazonian basin was perfomed. Results pointed to a great contribution of higher plants, based on TAR values and intensity of sitosterol, whereas the high content of hopanoid structures and lower mass alkanoic acid and alkanol indicated intense microbiological activity.
