Definition
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time
Skarns are formed during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, and/or marine origin

Etymology
From the Greek marmaros, shining stone and also from the English word marmoreal meaning marble-like

Formation
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
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 Marble and Skarn Properties
Know all about Marble and Skarn properties here. All properties of rocks are important as they define the type of rock and its application. Marble and Skarn belong to Metamorphic Rocks.Texture of Marble is Granular whereas that of Skarn is Earthy, Mud-rich, Rough. Marble appears Veined and Shiny and Skarn appears Dull. The luster of Marble is dull to pearly to subvitreous while that of Skarn is waxy and dull. Marble is available in black, blue, brown, grey, pink, white colors whereas Skarn is available in black, brown, colourless, green, grey, white colors. The commercial uses of Marble are cemetery markers, commemorative tablets, creating artwork, curling, laboratory bench tops, paper industry, tombstones, used in aquariums, whiting material in toothpaste, paint and paper and that of Skarn are creating artwork, gemstone, jewelry, metallurgical flux, source of magnesia (mgo).
