From the geological perspective, limestone formation takes place in two different environments, sedimentation in marine waters and by water evaporation during cave formation. Marine Environment to Form Limestone Most limestones form in clear, shallow marine waters - an environment where organisms can form calcium carbonate shells.Soft-sediment deformation in the São Paulo Formation. The São Paulo Formation preserves soft-sediment deformation structures in various stratigraphic horizons, but they are particularly abundant at the topmost strata of the succession, between 775 and 785 m asl. This study is concentrated at the structures preserved at the top of the succession.
