Description :
This study identifies and relates the physical and chemical characteristics of the surface sediment with the limestone bedrock in Guilin to assess the influence of the limestone dissolution process on sediment composition. A dual-zone environmental structure exists vertically downward from the surface in Guilin : the zone of unconsolidated clastic sediments predominantly acidic, and the zone of karstified limestone predominantly basic. The evidence suggests that the environment and process differ in these 2 zones. The chemical dissolution of limestone that formed tower karst of the region is not mainly responsible for the accumulation of clastic sediment on the surface.
