(a) Fossil diatom analysis results for location SZ1. The diagram shows selected taxa with a relative abundance of 5% in at least one sample. The scale of relative abundance is the same in (a–f). The specific sampling horizons from U1-1 to U5-2 are provided in the Supplementary Data S5. (b) Fossil diatom analysis results for location SZ3. (c) Fossil diatom analysis results for location SZ5. (d) Fossil diatom analysis results for vented sediments and paddy field soil at SZ6. (e) Fossil diatom analysis results for vented sediments, paddy field soil, and the light brown sand underlying paddy soil at SZ7. (f) Diatom assemblages within beach sand.
