The metamorphism of pyrite and pyritic ores an overview

Pyrrhotite in pyritic ores has often been attributed to the breakdown of pyrite during metamorphism It is now clear that pyrrhotite can be primary and that the presence of pyrrhotite with the pyrite provides a buffer that constrains sulphur activity during metamorphism Pyrite pyrrhotite ratios change during metamorphism as prograde heating results in sulphur release from pyrite to form
