Archaeological Significance
Formation
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.
Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.

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