Schist and Diamictite


Definition

Definition
Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone  
Schist is a medium grade metamorphic rock with medium to large, flat, sheet like grains in a preferred orientation

Formation

Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.  
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 Diamictite and Schist Properties

Know all about Diamictite and Schist properties here. All properties of rocks are important as they define the type of rock and its application. Diamictite belongs to Sedimentary Rocks while Schist belongs to Metamorphic Rocks.Texture of Diamictite is Clastic whereas that of Schist is Foliated, Platy. Diamictite appears Banded and Schist appears Layered and Shiny. The luster of Diamictite is grainy, pearly and vitreous while that of Schist is shiny. Diamictite is available in brown, buff colors whereas Schist is available in black, blue, brown, dark brown, green, grey, silver colors. The commercial uses of Diamictite are commemorative tablets, creating artwork, production of lime and that of Schist are used in aquariums, writing slates.
