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.
Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

All about Latite and Phonolite Properties
Know all about Latite and Phonolite properties here. All properties of rocks are important as they define the type of rock and its application. Latite and Phonolite belong to Igneous Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Phonolite is Granular. Latite appears Rough and Phonolite appears Banded and Foilated. The luster of Latite is subvitreous to dull while that of Phonolite is greasy to dull. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas Phonolite is available in brown, buff, cream, 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 Phonolite are cemetery markers, creating artwork.
