Boninite and Suevite
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
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
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 Boninite and Suevite Properties
Know all about Boninite and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Boninite belongs to Igneous Rocks while Suevite belongs to Metamorphic Rocks.Texture of Boninite is Aphanitic to Porphyritic whereas that of Suevite is Earthy. Boninite appears Dull and Soft and Suevite appears Banded. The luster of Boninite is vitreous while that of Suevite is earthy. Boninite is available in bluish - grey, brown, colourless, green, grey colors whereas Suevite is available in black, brown, colourless, green, grey, pink 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 Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
