Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas

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

All about Basanite and Laterite Properties
Know all about Basanite and Laterite properties here. All properties of rocks are important as they define the type of rock and its application. Basanite belongs to Igneous Rocks while Laterite belongs to Sedimentary Rocks.Texture of Basanite is Aphanitic to Porphyritic whereas that of Laterite is Earthy, Massive, Porphyritic. Basanite appears Glassy or Pearly and Laterite appears Rough and Banded. The luster of Basanite is waxy and dull while that of Laterite is dull. Basanite is available in black, brown, green, grey, red, white colors whereas Laterite is available in brown, buff, red colors. The commercial uses of Basanite are as a touchstone, creating artwork, gemstone, in fire-starting tools, manufacture of tools, metallurgical flux, jewelry, to ignite fire, used in flintlock firearms and that of Laterite are an oil and gas reservoir, source of bauxite, used in aquariums.
