Formation
Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

All about Lamprophyre and Jadeitite Properties
Know all about Lamprophyre and Jadeitite properties here. All properties of rocks are important as they define the type of rock and its application. Lamprophyre belongs to Igneous Rocks while Jadeitite belongs to Metamorphic Rocks.Texture of Lamprophyre is Porphyritic whereas that of Jadeitite is Earthy. Lamprophyre appears Dull, Banded and Foilated and Jadeitite appears Rough and Dull. The luster of Lamprophyre is subvitreous to dull while that of Jadeitite is waxy and dull. Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Jadeitite is available in black, brown, colourless, green, grey, white 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 Jadeitite are commemorative tablets, creating artwork, jewelry.
