Source rock characterisation and petroleum system modelling: a review of marginal marine deposit in the Permo-Triassic Sydney Basin, Australia

The marginal marine sediments are common in the Permo-Triassic Sydney Basin, and it has not been previously evaluated for source rock and petroleum system modelling. The economic potentials of the marginal marine environment are great, with enormous information in the literature that deals with the development of these deposits. The wide use of major, trace, and rare earth elements for basin analysis studies to unravel the geochemical signatures of sedimentary succession using the discriminatory diagrams fall short of addressing sediments from different geotectonic environments. Using a systematic review, the study find that typical approach to the evaluation of marginal marine deposit with regards to petroleum systems as applicable to any basin has not profitably enhanced its exploration at commercial level. This review provides new insight into source rock, sediment supply, and depositional patterns of the marginal marine deposits in the Permo-Triassic Sydney Basin and its implication to the dearth in petroleum prospectivity.
