In a region where proxies for palaeoenvironmental reconstruction are terribly lacking, this study assessed the potentials of paleosols (fossil soils) to answer fundamental questions about weathering, pedogenic intensity and environmental change using macromorphology, geochemistry and clay mineralogy. SiO2 is the dominant major oxide (40.6- 98.9 wt. %) followed by CaO (0.02-29.6 wt. %), Fe2O3 (0.48- 2.64 wt. %), MgO (0.14 – 1.81 wt. %) and Al2O3 (0.29 – 0.93 wt. %). The clay-sized minerals present in the paleosols are sepiolite, quartz, calcite and kaolinite. The carbonates had strong positive correlation with Sr (R2 = 0.935), while Fe2O3 had weak positive correlation with TiO2 (R2 = 0.0187). PL1 developed on materials of fluvial origin and is genetically immature with A/C horizons. In compar...
