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.
Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.

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