Suevite and Ignimbrite
Definition
Definition
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.
Ignimbrite is a volcanic rock consisting mainly of pumice fragments, formed by the consolidation of material deposited by pyroclastic flows

Formation
Formation
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.
Ignimbrites are formed from very poorly sorted mixture of volcanic ash or tuff and pumice lapilli, commonly with scattered lithic fragments.

All about Suevite and Ignimbrite Properties
Know all about Suevite and Ignimbrite properties here. All properties of rocks are important as they define the type of rock and its application. Suevite belongs to Metamorphic Rocks while Ignimbrite belongs to Igneous Rocks.Texture of Suevite is Earthy whereas that of Ignimbrite is Aphanitic. Suevite appears Banded and Ignimbrite appears Dull, Vesicular and Foilated. The luster of Suevite is earthy while that of Ignimbrite is vitreous to dull. Suevite is available in black, brown, colourless, green, grey, pink colors whereas Ignimbrite is available in beige, black, brown, grey, pink, white colors. The commercial uses of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo) and that of Ignimbrite are cemetery markers, commemorative tablets, creating artwork.
