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.
Pyrolite 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 Latite and Pyrolite Properties
Know all about Latite and Pyrolite properties here. All properties of rocks are important as they define the type of rock and its application. Latite and Pyrolite belong to Igneous Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Pyrolite is Phaneritic. Latite appears Rough and Pyrolite appears Rough and Shiny. The luster of Latite is subvitreous to dull while that of Pyrolite is shiny. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas Pyrolite is available in dark greenish - 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 Pyrolite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds.
