Original data for color parameters of aeolian sand-palaeosol sequences and their potential influencing factors

This supplementary material primarily comprises color parameters (L*, a*, and b*), loss-on-ignition (LOI), carbonate content, and total iron oxide (TFe₂O₃) measurements from four representative aeolian sand-palaeosol sequences in the ASMB region of northern China.

本补充材料主要包含颜色参数（L*、a*、b*）、烧失量（loss-on-ignition，LOI）、碳酸盐含量以及总氧化铁（TFe₂O₃）的测量数据，这些数据来源于中国北方ASMB区域的四个代表性风成砂-古土壤序列。
