general
Talc is a metamorphic mineral resulting from the metamorphism of
magnesian minerals such as serpentine, pyroxene, amphibole,
olivine, in the presence of carbon dioxide and water. This is known
as talc carbonation or steatization and produces a suite of rocks
known as talc carbonates.
Talc is primarily formed via hydration and carbonation via the
following reaction;
serpentine + carbon dioxide → talc + magnesite + water
2 Mg3Si2O5(OH)4 + 3CO2 → Mg3Si4O*0(OH)2 + 3 MgCO3 + 3 H2O
