Skarns are formed during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, and/or marine origin
From an old Swedish mining term originally used to describe a type of silicate gangue or waste rock.
Fine Grained Rock, Opaque Rock

Host Rock for Lead, Zinc and Copper Deposits
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Skarn is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
