Chemical Weathering Processes on the Earth’s Surface

摘要: The exhumation of rocks from the Earth’s crust implies that they must adjust thermodynamically to conditions existing on surface, which are extremely different those prevailing during their formation, with higher temperature, pressure, and often exposed chemically aggressive fluids. processes involved in chemical weathering, such as dissolution, hydrolysis, etc., at core adjustment mechanism, transforming solid, usually refractory rock material, into particles-typically stripped part original components dissolved phases, both amenable be transported continents sea. Although anthropogenic actions have altered natural denudation rates, still a relatively minor portion material thus produced stays for longer period continents, temporarily sequestered depositional systems. most important participants weathering scenario mineral silicate redox reactions.
