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.
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

All about Latite and Andesite Properties
Know all about Latite and Andesite properties here. All properties of rocks are important as they define the type of rock and its application. Latite and Andesite belong to Igneous Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Andesite is Aphanitic to Porphyritic. Latite appears Rough and Andesite appears Dull and Soft. The luster of Latite is subvitreous to dull while that of Andesite is vitreous. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas Andesite is available in bluish - grey, grey, pink, yellow 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 Andesite are commemorative tablets, creating artwork.
