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.

Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.

All about Latite and Vogesite Properties

Know all about Latite and Vogesite properties here. All properties of rocks are important as they define the type of rock and its application. Latite and Vogesite belong to Igneous Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Vogesite is Porphyritic. Latite appears Rough and Vogesite appears Dull, Banded and Foilated. The luster of Latite and Vogesite is subvitreous to dull. Latite is available in black, brown, green, grey, pink, white colors whereas Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey 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 Vogesite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
