Muck over marl
After discussing this site and doing a bit of research, we concluded that the whitish layer is marl (Lma horizon) formed by near-shore lakebed sediments from a past environment. The marl was also enhanced by the accumulation of secondary carbonates which were discharged in the calcium-rich groundwater through the stratified soils. Marl is a kind of limnic material (freshwater lake sediment) that is high in calcium carbonate and generally feels chalky or silty.
