Formation
Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Harzburgite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Lamprophyre and Harzburgite Properties
Know all about Lamprophyre and Harzburgite properties here. All properties of rocks are important as they define the type of rock and its application. Lamprophyre and Harzburgite belong to Igneous Rocks.Texture of Lamprophyre is Porphyritic whereas that of Harzburgite is Phaneritic. Lamprophyre appears Dull, Banded and Foilated and Harzburgite appears Rough and Shiny. The luster of Lamprophyre is subvitreous to dull while that of Harzburgite is shiny. Lamprophyre and Harzburgite are available in black, bluish - grey, brown, dark greenish - grey, green, grey 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 Harzburgite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds.
