Slate and Suevite


Suevite and Slate


Definition

Definition
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism   
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation

Formation
Slate is a low grade metamorphic rock that is generally formed by metamorphosis of mudstone or shale, under relatively low pressure and temperature conditions.   
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.

All about Slate and Suevite Properties

Know all about Slate and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Slate and Suevite belong to Metamorphic Rocks.Texture of Slate is Foliated whereas that of Suevite is Earthy. Slate appears Dull and Suevite appears Banded. The luster of Slate is dull while that of Suevite is earthy. Slate is available in black, brown, buff, green, light to dark grey, purple, red, shades of blue colors whereas Suevite is available in black, brown, colourless, green, grey, pink colors. The commercial uses of Slate are blackboards, commemorative tablets, laboratory bench tops, standard material for the bed of billiard table, standard material for the beds of pool and snooker table, tombstones, used in aquariums, writing slates and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
