Holocene coastal sedimentary evolution of the southern Taihu Plain, East China
Description
Sediment cores SZ24 and SZ50 were collected from the coastal plain in the southern Taihu region. Core SZ24 is located at 120°32′18.46″E, 30°52′29.12″N, with an elevation of 1.61 m, while core SZ50 is located at 120°27′45.56″E, 30°40′51.61″N, with an elevation of 3.08 m. Elevations are reported relative to the 1985 National Vertical Datum. There is pollen data from core SZ24. And there are grain-size data from cores SZ24 and SZ50.

Steps to reproduce
Pollen grains were generally observed at a magnification of 400×. Identification was based primarily on the published papers or books in China (Academia Sinica, 1976; Academia Sinica, 1979; Tang, 2016). Most samples contained more than 400 pollen grains. However, some samples had very low pollen concentrations, with fewer than 300 grains counted, and were therefore excluded from further analysis. Grain-size analyses were conducted on all the samples in the core SZ24 and core SZ50 using a Mastersizer 3000, and mud content (grain size ≤ 63 μm) was subsequently calculated.
