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.
Schist formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

All about Latite and Schist Properties
Know all about Latite and Schist properties here. All properties of rocks are important as they define the type of rock and its application. Latite belongs to Igneous Rocks while Schist belongs to Metamorphic Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Schist is Foliated, Platy. Latite appears Rough and Schist appears Layered and Shiny. The luster of Latite is subvitreous to dull while that of Schist is shiny. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas Schist is available in black, blue, brown, dark brown, green, grey, silver 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 Schist are used in aquariums, writing slates.
