Abstract: A method for determining geologic age of hydrocarbon samples, such as oils, using novel age biomarkers may comprise: measuring a concentration or related value of triaromatic dionsteranes (TAD) in a hydrocarbon sample, migrated oil sample, from a North Atlantic conjugate margin (NAM); calculating a TAD index for the hydrocarbon sample based on the concentration or the related value of the TAD; and predicting an age of the hydrocarbon sample based on a correlation between a hydrocarbon age and the TAD index.
