Definition

Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities

A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

Formation

Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

All about Scoria and Serpentinite Properties

Know all about Scoria and Serpentinite properties here. All properties of rocks are important as they define the type of rock and its application. Scoria belongs to Igneous Rocks while Serpentinite belongs to Metamorphic Rocks.Texture of Scoria is Vesicular whereas that of Serpentinite is Earthy. Scoria appears Glassy and Vesicular and Serpentinite appears Rough and Dull. The luster of Scoria is subvitreous to dull while that of Serpentinite is waxy and dull. Scoria is available in black, brown, dark grey to black, red colors whereas Serpentinite is available in black, brown, green, grey, white 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 Serpentinite are commemorative tablets, creating artwork.
