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
  
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

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.
  
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

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