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
Monzogranite is a type of igneous rock and belongs to biotite granite rocks that are considered to be the final fractionation product of magma

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.
Monzogranite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Skarn and Monzogranite Properties
Know all about Skarn and Monzogranite properties here. All properties of rocks are important as they define the type of rock and its application. Skarn belongs to Metamorphic Rocks while Monzogranite belongs to Igneous Rocks.Texture of Skarn is Earthy, Mud-rich, Rough whereas that of Monzogranite is Porphyritic. Skarn appears Dull and Monzogranite appears Veined or Pebbled. The luster of Skarn is waxy and dull while that of Monzogranite is dull to grainy with sporadic parts pearly and vitreous. Skarn is available in black, brown, colourless, green, grey, white colors whereas Monzogranite is available in black, grey, orange, pink, white colors. The commercial uses of Skarn are creating artwork, gemstone, jewelry, metallurgical flux, source of magnesia (mgo) and that of Monzogranite are cemetery markers, commemorative tablets, creating artwork, curling, tombstones.
