Åkermanite (Ca2Mg[Si2O7]) is a melilite mineral of the sorosilicate group containing calcium magnesium silicon and oxygen. It is a product of contact metamorphism of siliceous limestones and dolostones and rocks of sanidinite facies. Sanidinite facies represent the highest conditions of temperature of contact metamorphism and are characterized by the absence of hydrous minerals. It has a density of 2.944 g/cm3.
