Definition
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas
Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface

Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

All about Laterite and Basaltic Trachyandesite Properties
Know all about Laterite and Basaltic Trachyandesite properties here. All properties of rocks are important as they define the type of rock and its application. Laterite belongs to Sedimentary Rocks while Basaltic Trachyandesite belongs to Igneous Rocks.Texture of Laterite is Earthy, Massive, Porphyritic whereas that of Basaltic Trachyandesite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular. Laterite appears Rough and Banded and Basaltic Trachyandesite appears Dull and Soft. The luster of Laterite is dull while that of Basaltic Trachyandesite is not available. Laterite is available in brown, buff, red colors whereas Basaltic Trachyandesite is available in black, brown, light to dark grey colors. The commercial uses of Laterite are an oil and gas reservoir, source of bauxite, used in aquariums and that of Basaltic Trachyandesite are an oil and gas reservoir, commemorative tablets, creating artwork.
