1.1 Definition

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'.

Lamprophyre is uncommon igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks and small intrusions

5 Formation

5.1 Formation

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.

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

All about Serpentinite and Lamprophyre Properties

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