Features
Always found as volcanic pipes over deep continental crust, Host rock for Diamond, Is one of the oldest rock, Surfaces are often shiny
Available in Lots of Colors and Patterns, Generally rough to touch, Surfaces are often shiny
Archaeological Significance
Formation
Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

All about Lamprophyre and Scoria Properties
Know all about Lamprophyre and Scoria properties here. All properties of rocks are important as they define the type of rock and its application. Lamprophyre and Scoria belong to Igneous Rocks.Texture of Lamprophyre is Porphyritic whereas that of Scoria is Vesicular. Lamprophyre appears Dull, Banded and Foilated and Scoria appears Glassy and Vesicular. The luster of Lamprophyre and Scoria is subvitreous to dull. Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Scoria is available in black, brown, dark grey to black, red colors. The commercial uses of Lamprophyre are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo) and that of Scoria are as a traction material on snow-covered roads, creating artwork, high-temperature insulation, in gas barbecue grills.
