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

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.
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.

All about Suevite and Shale Properties
Know all about Suevite and Shale properties here. All properties of rocks are important as they define the type of rock and its application. Suevite belongs to Metamorphic Rocks while Shale belongs to Sedimentary Rocks.Texture of Suevite is Earthy whereas that of Shale is Clastic, Splintery. Suevite appears Banded and Shale appears Muddy. The luster of Suevite is earthy while that of Shale is dull. Suevite is available in black, brown, colourless, green, grey, pink colors whereas Shale is available in black, brown, buff, green, grey, red, yellow colors. The commercial uses of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo) and that of Shale are creating artwork, pottery.
