Chemical weathering intensity
WebJan 10, 2014 · The weathering intensity in the flow, as indicated by the clay content, follows the aforementioned morphology transition, with a sharp increase in pedogenetic phyllosilicates near the base that is coincident with the appearance of the banded texture. WebJan 1, 2024 · Most processes of chemical weathering depend on the presence of water and its movement through the massifs. These processes generally include solution, and the intensity with which it acts depends mainly on the amount of water circulating in the massifs, the solubility of minerals, and the pH of the water. 1.
