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.
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.

All about Foidolite and Latite Properties
Know all about Foidolite and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Foidolite and Latite belong to Igneous Rocks.Texture of Foidolite is Earthy whereas that of Latite is Aphanitic to Porphyritic. Foidolite appears Dull and Latite appears Rough. The luster of Foidolite and Latite is subvitreous to dull. Foidolite and Latite are available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Foidolite are cemetery markers, commemorative tablets, creating artwork and that of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
