Current advances in the research of turbidity current deposits: Reinterpretation of the Bouma sequence and submarine fan deposits

The present paper gives a reinterpretation of turbidity currents,turbidites and the Bouma sequence. In the research of modern submarine fans,the Bouma sequence can't represent the complete processes of turbidity current deposition. The sedimentary models indicated by the Bouma sequence,in fact,should be the combination and reworking of debris flows,turbidity currents and bottom currents,and thus the Bouma sequence can't be selected as the sole model for the recognition and prediction of turbidity current deposits. Instead,sedimentary models should be constructed according to distinct sedimentary environments due to the variety of turbidity current deposition. In addition,the turbidity current models will be further evidenced by modern deep-sea deposition in the future research.
