According to the mean values and variation coefficients of the hydrocarbon gases, aromatic and condensed rings aromatic hydrocarbons of the seabed sediments, the geochemical fields of the three depressions are different. The geochemical field of the eastern depression is heavily heterogeneous for all indices, the field of the middle depression is the mixture of the homogeneous and heterogenous, and the western depression are characterized by slightly heterogeneous up to homogeneous anomalies. The geochemical anomalies of hydrocarbons are mainly distributed along the edge faults of the depressions and second sinks. It suggests that the geochemical fields and anomalies are controlled by faults, especially the edge faults of depressions.
