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.   
Schist formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

All about Suevite and Schist Properties

Know all about Suevite and Schist properties here. All properties of rocks are important as they define the type of rock and its application. Suevite and Schist belong to Metamorphic Rocks.Texture of Suevite is Earthy whereas that of Schist is Foliated, Platy. Suevite appears Banded and Schist appears Layered and Shiny. The luster of Suevite is earthy while that of Schist is shiny. Suevite is available in black, brown, colourless, green, grey, pink colors whereas Schist is available in black, blue, brown, dark brown, green, grey, silver colors. The commercial uses of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo) and that of Schist are used in aquariums, writing slates.
