Fig. 7. Lantian Section: field-observed pedostratigraphy and laboratory data. Md (µm): median size; <10 µm (%): percentage of <10-µm fraction; <2 µm (%): percentage of <2-µm fraction; CaCO3 (%): percentage of carbonate; and 
: magnetic susceptibility (10–7 m3 kg–1). The vertically shaded area indicates the chronological discord between parent material (older loess L2) and paleosol (later developed S1). The horizontally shaded area is carbonate accumulation zone for all three paleosols (S1S1, S1S2, S1S3).
