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.
Foidolites 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 Foidolite Properties
Know all about Latite and Foidolite properties here. All properties of rocks are important as they define the type of rock and its application. Latite and Foidolite belong to Igneous Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Foidolite is Earthy. Latite appears Rough and Foidolite appears Dull. The luster of Latite and Foidolite is subvitreous to dull. Latite and Foidolite are available in black, brown, colourless, green, 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 Foidolite are cemetery markers, commemorative tablets, creating artwork.
