The type of residue left behind by carbonate rocks affects how intensely their red weathering crusts develop. The more mature the residue, the more intense the weathering. Different types of carbonate rocks have different residues, leading to varying weathering intensities. As the residue matures, the weathering potential of the crust decreases, making it easier to reach a weathering equilibrium. The dissolution of carbonate in the residue speeds up the weathering of silicate components. Weathering crusts of carbonate rocks are more vulnerable to weathering than those of crystalline rocks, like basalt and granite.
