Definition
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

All about Laterite and Suevite Properties
Know all about Laterite and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Laterite belongs to Sedimentary Rocks while Suevite belongs to Metamorphic Rocks.Texture of Laterite is Earthy, Massive, Porphyritic whereas that of Suevite is Earthy. Laterite appears Rough and Banded and Suevite appears Banded. The luster of Laterite is dull while that of Suevite is earthy. Laterite is available in brown, buff, red colors whereas Suevite is available in black, brown, green, grey, pink colors. The commercial uses of Laterite are an oil and gas reservoir, source of bauxite, used in aquariums and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
