Scoria and Suevite
Definition
Definition
Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation
Formation
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
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 Scoria and Suevite Properties
Know all about Scoria and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Scoria belongs to Igneous Rocks while Suevite belongs to Metamorphic Rocks.Texture of Scoria is Vesicular whereas that of Suevite is Earthy. Scoria appears Glassy and Vesicular and Suevite appears Banded. The luster of Scoria is subvitreous to dull while that of Suevite is earthy. Scoria is available in black, brown, dark grey to black, red colors whereas Suevite is available in black, brown, colourless, green, grey, pink colors. The commercial uses of Scoria are as a traction material on snow-covered roads, creating artwork, high-temperature insulation, in gas barbecue grills and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
