6.4 What is the role of fluid in metamorphism?

• Adding fluid during metamorphism
• Often during low-grade metamorphism (similar to chemical weathering reactions, but higher temperature and pressures)
• 2 Mg2SiO4 + 2 H2O + CO2 Mg3Si2O5(OH)4 + MgCO3
• Mg-olivine water carbon dioxide serpentine magnesite
