Because of the great variety of lacustrine-source depositional characteristics and biological consortia, identification of a universally applicable indicator of freshwater or brackish-water organic input for crude oils and rock extracts has proven el

Two C26 sterane ratios, the 24-nordiacholestane ratio (NDR) and the 24-norcholestane ratio (NCR), are useful for assessing petroleum source age. Values for these parameters generally increase in the Cretaceous when diatoms were rapidly radiating and

Biomarkers, molecular fossils, are organic compounds in Holocene to Precambrian sedimentary deposits that can be related to specific chemical compounds produced in the biosphere. We demonstrate here that 24-norcholestane biomarkers, i.e., C26 sterane
