Definition
Skarns are formed during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, and/or marine origin
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Archaeological Significance
Formation
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.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

All about Skarn and Suevite Properties
Know all about Skarn and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Skarn and Suevite belong to Metamorphic Rocks.Texture of Skarn is Earthy, Mud-rich, Rough whereas that of Suevite is Earthy. Skarn appears Dull and Suevite appears Banded. The luster of Skarn is waxy and dull while that of Suevite is earthy. Skarn is available in black, brown, green, grey, white colors whereas Suevite is available in black, brown, green, grey, pink colors. The commercial uses of Skarn are creating artwork, gemstone, jewelry, metallurgical flux, source of magnesia (mgo) and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
