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.
Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.

All about Latite and Anorthosite Properties
Know all about Latite and Anorthosite properties here. All properties of rocks are important as they define the type of rock and its application. Latite and Anorthosite belong to Igneous Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Anorthosite is Foliated, Glassy. Latite appears Rough and Anorthosite appears Layered, Banded, Veined and Shiny. The luster of Latite is subvitreous to dull while that of Anorthosite is pearly to subvitreous. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish 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 Anorthosite are creating artwork, curling.
