It typically results in epidote–chlorite–albite alteration and veining or fracture filling with the mineral assemblage along with pyrite.The alteration occurs due to hot fluids that have a high sodium ion composition. This is typically due to fluids that have lost potassium ions in potassic alteration and gained sodium ions."@en }
