Figure 11
Proportions of Sn⁴⁺ and Sn²⁺ in Na₂O.2SiO₂ glass (Johnston, 1965

) as a function of oxygen fugacity (fO₂) and temperature [equation (66)

]. Several oxygen buffers are shown; NNO = Ni–NiO, FMQ = fayalite–magnetite–quartz, IW = iron–wüstite. Most terrestrial igneous rocks have oxygen fugacities within ±2 Log-units of the FMQ buffer, where Sn⁴⁺ and Sn²⁺ could co-exist.
