Shale and Suevite
Definition
Definition
Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation
Formation
Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.
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 Shale and Suevite Properties
Know all about Shale and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Shale belongs to Sedimentary Rocks while Suevite belongs to Metamorphic Rocks.Texture of Shale is Clastic, Splintery whereas that of Suevite is Earthy. Shale appears Muddy and Suevite appears Banded. The luster of Shale is dull while that of Suevite is earthy. Shale is available in black, brown, buff, green, grey, red, yellow colors whereas Suevite is available in black, brown, colourless, green, grey, pink colors. The commercial uses of Shale are creating artwork, pottery and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
