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

Archaeological Significance
Formation
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.
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.

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