Abstract:
Representative carbonate contourite is discovered based on field outcrop descriptions and laboratory analysis based on detailed study of Zhuozishan section. This paper gets the portion of the carbonate contourite with hypothetical Fischer diagram showing changes in accommodation space as a function of cycle number. Using the chemical data of field samples, it is found that the carbonate contourite in deep sea may yield hydrocarbon effectively. It is significant to find potential mineral from contourite study. In the future, we should synthesize multidisciplinary approaches such as identification of seismic wave and remote sensing etc. and establish some effective discriminating indicators so as to advance the research ulteriorly and make it a more perfect research field in the marine sedimentology.
