  • Geological Society - Chemical Weathering

    In particular, limestone is weathered by rainwater containing dissolved CO2, (this process is sometimes called carbonation). Hydrolysis - the breakdown of rock by acidic water to produce clay and soluble salts. Oxidation - the breakdown of rock by oxygen and water, often giving iron-rich rocks a rusty-coloured weathered surface.
