Metamorphic Mineral Reactions

Calcite + Quartz = Wollastonite + Carbon Dioxide
CaCO₃ + SiO₂  = CaSiO₃ + CO₂

Brucite + Silica (in hydrothermal fluid) + Calcite = Monticellite + Carbon Dioxite + Water
Mg(OH)₂ + SiO₂ + CaCO₃ = CaMgSiO₄ + CO₂ + H₂O

Analcime + Quartz  =  Albite + Water
NaAlSi₂O₆^.H₂O + SiO₂  =   NaAlSi₃O₈ + 2H₂O

Chlorite + Quartz = Garnet + Water
2(Mg,Fe,Mn)_4.5Al₃Si_2.5O₁₀ +  4SiO₂  =  3(Mg,Fe,Mn)₃Al₂Si₃O₁₂ +  8H₂O

Muscovite  =  K-spar + corrundum + Water
KAl₂(AlSi₃O₁₀)(OH)₂  =  KAlSi₃O₈ + Al₂O₃ + H₂O

Muscovite + Quartz  =  K-spar + Sillimanite + Water
KAl₂(AlSi₃O₁₀)(OH)₂ + SiO₂  =  KAlSi₃O₈ + Al₂SiO₅ + H₂O

Biotite + Quartz = Orthopyroxene + Kspar + Water
K(Mg,Fe)₃Si₄O₁₀(OH)₂ + 3SiO₂  =  KAlSi₃O₈ + 3(Mg,Fe)SiO₃ + H₂O

Albite = Jadeite + Quartz
NaAlSi₃O₈  =  NaAlSi₂O₆  + SiO₂
