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

Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture

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.

Latite 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 Latite Properties

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