a Al flux at the Bajiazui section17. b SiO2/Al2O3 from the Xifeng section20. c Zr/Rb from the Jiaxian red clay section26. d Median grain size from the Xifeng section20. e, f Fine (5–16 μm) and coarse (>20 μm) particle concentration from the Shilou section56. Red smooth curves are fitted using the MatLab LOWESS function. g, h Cold-aridiphilous (CA) and thermo-humidiphilous (TH) terrestrial mollusk changes in the Dongwan red clay57.
