5 Formation

5.1 Formation

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.

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 Trachyte and Latite Properties

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