[[file:predicting-preservation-and-destruction-of-accumulations_fig11-4.png|thumb|{{figure number|1}}Whole-oil gas chromatographs of a heavily biodegraded oil (A) and its undegraded precursor (B) on an example from offshore Louisiana.]]
The geochemical signatures of biodegradation are very distinctive. [[:file:predicting-preservation-and-destruction-of-accumulations_fig11-4.png|Figure 1]] shows whole-oil gas chromatographs of a heavily biodegraded oil (A) and its undegraded precursor (B) on an example from offshore Louisiana. Normal paraffins (sharp peaks in B) have been removed by bacterial action.
