1 Definition

1.1 Definition

Ignimbrite is a volcanic rock consisting mainly of pumice fragments, formed by the consolidation of material deposited by pyroclastic flows

During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

5 Formation

5.1 Formation

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

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 Ignimbrite and Suevite Properties

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