Formation

Formation
Schist formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.   
Monzonite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Schist and Monzonite Properties

Know all about Schist and Monzonite properties here. All properties of rocks are important as they define the type of rock and its application. Schist belongs to Metamorphic Rocks while Monzonite belongs to Igneous Rocks.Texture of Schist is Foliated, Platy whereas that of Monzonite is Phaneritic. Schist appears Layered and Shiny and Monzonite appears Shiny. The luster of Schist is shiny while that of Monzonite is subvitreous to dull. Schist is available in black, blue, brown, dark brown, green, grey, silver colors whereas Monzonite is available in black, brown, light to dark grey, white colors. The commercial uses of Schist are used in aquariums, writing slates and that of Monzonite are creating artwork.
