Abstract
Numerical simulations of a weathering profile on granite containing 10–8 mol/L Sn (whose average content in the Earth’s crust is 0.00025%) by the SELECTOR program package indicate that cassiterite SnO2 solubility under both oxidizing and reducing conditions is no higher than 10–10 mol/L within the pH range of 3 to 11. The only ion occurring in equilibrium with cassiterite is the neutral Sn(OH)4(aq)0 complex, which was detected in both oxidizing and reducing environments.
