Suevite and Minette
Definition
Definition
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.
Minette is a variety of Lamprophyre and is porphyritic alkaline igneous rock which is mainly dominated by biotite and potassic feldspar

Formation
Formation
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.
Minette formation takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

All about Suevite and Minette Properties
Know all about Suevite and Minette properties here. All properties of rocks are important as they define the type of rock and its application. Suevite belongs to Metamorphic Rocks while Minette belongs to Igneous Rocks.Texture of Suevite is Earthy whereas that of Minette is Porphyritic. Suevite appears Banded and Minette appears Dull, Banded and Foilated. The luster of Suevite is earthy while that of Minette is subvitreous to dull. Suevite is available in black, brown, colourless, green, grey, pink colors whereas Minette is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. The commercial uses of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo) and that of Minette are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
