This type of metamorphism affects very large areas and is known as regional metamorphism In the vicinity of igneous intrusions where the surrounding rocks are heated by the ascending hot magma

Gypsum as a precursor to pyrrhotite in metamorphic rocks

During low-grade regional metamorphism, pyrrhotite can form from gypsum by the reaction: CaSO 4 ·2H 2 O+Fe sol 2+ +2C org →FeS+Ca sol 2+ +2H 2 O+2CO 2 This reaction takes place in the anchizone, below ∼350°C and might be initiated by the thermal dehydration of gypsum (∼200°C) and aided by the generation of gaseous hydrocarbons
