Abstract:

Both the sequence stratigraphy and source-to-sink system are modern geoscience disciplines with theories and methodologies being widely applied and employed. However, the connections and distinctions between the two have not been discussed thoroughly for a better discipline integration and synergy. The sequence stratigraphy is focused on establishing high-resolution isochronous stratigraphic frameworks for sinks and trying to reveal their sedimentary filling processes, temporal-spatial distribution patterns and genetic mechanisms. While the source-to-sink theory expands further to transport areas and provenances, tracing the dynamic responses of denudation, transport, and accumulation of sediments in multiple dimensions, and determining the driving mechanisms and prototype patterns of sediment partition from source to sink. The internal connections between the two disciplines are reflected mostly through the analysis of denudation-sedimentation response and quantitative prediction of sedimentary bodies in isochronous stratigraphic frameworks, while their distinctions are mainly illustrated during the description of different key elements and structures of inner sequence units. Judging by the current development trends, we could expect a rapid development of the methodology systems of the two disciplines in respects of standardization of their application, combination of ancient and modern data, and quantitative analyses and prediction through multi-disciplinary and multi-parameter integration.
