| http://www.w3.org/ns/prov#value | - Carbonate weathering is illustrated by the following congruent dissolution reaction of calcite: CaCO3 + H2O +CO2 = Ca2+ + 2HCO3- These reactions show that bicarbonate and cations such as Ca and Mg are mainly derived from mineral weathering, whereas chloride, sulphate, nitrate and phosphate have alternative sources (Appelo and Postma, 2005).
