The principles, advantages and disadvantages of immobilization, soil washing and phytoremediation techniques

6 Igneous Rocks and Silie Minerals – Mineralogy

It cannot crystallize any minerals in Bowen’s reaction series except quartz because it does not contain the necessary elements. It will skip all the other minerals and just form quartz. On the other hand, if a melt were 100% Mg 2 SiO 4 , it would crystallize forsterite (olivine of composition Mg 2 SiO 4 ) and be completely solidified.
