Mapping network flows through sedimentary deposits: A case study from the Quaternary of the Po Plain (Italy)
Understanding the biosedimentary response of marginal marine systems to relative sea-level changes is critical for several theoretical and applied questions. At the basin-level, it is generally evaluated based on a sequence-stratigraphic interpretation of the sediment succession. Such a time-environment conceptualization requires chronologically well-constrained successions to enable precise stratigraphic correlations. I am working on understanding the modular structure of a depositional basin, independently of the sequence stratigraphic interpretation, by mapping information flows directly through the sediment succession. A case study on Quaternary sediments of the Po Plain in southern Italy illustrates how a networks-based analysis may reveals some modular patterns in the basin structure that cannot be retrieved from standard methods.
