Boninite and Laterite
Definition
Definition
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas

Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

All about Boninite and Laterite Properties
Know all about Boninite and Laterite properties here. All properties of rocks are important as they define the type of rock and its application. Boninite belongs to Igneous Rocks while Laterite belongs to Sedimentary Rocks.Texture of Boninite is Aphanitic to Porphyritic whereas that of Laterite is Earthy, Massive, Porphyritic. Boninite appears Dull and Soft and Laterite appears Rough and Banded. The luster of Boninite is vitreous while that of Laterite is dull. Boninite is available in bluish - grey, brown, colourless, green, grey colors whereas Laterite is available in brown, buff, red colors. The commercial uses of Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo) and that of Laterite are an oil and gas reservoir, source of bauxite, used in aquariums.
