Fig. 4: The analysis results of the top 600 cm of core MD18-3545.

The charts from left to right are particle median size, sorting, kurtosis, skewness, core photo and CT image, respectively. Based on the core analysis results, we could distinguish four sedimentary periods and sediment facies in each period. The black arrows with age numbers indicate the radiocarbon dating depths and calibrated results (in median). The light purple stripes indicate the layers of coarser sediments in the core segment.
