Definition
Metapelite is an old and currently not widely used field geological term for a clay rich fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone
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
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

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