The changes of material composition, grain size and chemical weathering proxies. The values of K/Al and CIA of the silicate fractions from (a) MD12-3432, (b) ZHS-176, (c) MD12-3429, and (d) DLW3101. The semi-transparent lines represent the original data, and the bold lines are 10-point running averages in (a), (c) and (d) and 50-point running averages in (b) and (f). The mean grain size (Mz) and clay mineral assemblage variations from (e) MD12-3432 (Chen et al. 2017a, b) and (f) ZHS-176 (Ge et al. 2010; Zhang et al. 2013). g The mean grain size (Mz) and sediment compositions in DLW3101 (modified from Zhou et al. 2018). See Fig. 5 for the meaning of CIA
