Weathering - The Chemical process
Granite contains four types of minerals - Alkali feldspar, Quartz, Plagioclase feldspar and Olivine. Natural chemical agents react with these minerals slowly and results in clay.
Water combines with Carbon Dioxide and the resulting acid reacts with the granite materials as follows:
K2O.Al2O3.6SiO2 + 2H2O+CO2 = Al2O3.SiO2.2H2O + 4SiO2 + K2CO3
