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

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.
Pegmatite rock is holocrystalline, intrusive igneous rock which is formed by partial melting and dewatering during the process of metamorphism.

All about Suevite and Pegmatite Properties
Know all about Suevite and Pegmatite properties here. All properties of rocks are important as they define the type of rock and its application. Suevite belongs to Metamorphic Rocks while Pegmatite belongs to Igneous Rocks.Texture of Suevite is Earthy whereas that of Pegmatite is Pegmatitic. Suevite appears Banded and Pegmatite appears Layered, Banded, Veined and Shiny. The luster of Suevite is earthy while that of Pegmatite is grainy, pearly and vitreous. Suevite is available in black, brown, colourless, green, grey, pink colors whereas Pegmatite is available in black, brown, cream, green, grey, pink, red, rust, silver, white, yellow colors. The commercial uses of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo) and that of Pegmatite are creating artwork, jewelry, source of corundum, tourmalines, beryls and topaz.
