Formation
Formation
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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

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