5 Formation
5.1 Formation
Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.

All about Lamprophyre and Anorthosite Properties

Know all about Lamprophyre and Anorthosite properties here. All properties of rocks are important as they define the type of rock and its application. Lamprophyre and Anorthosite belong to Igneous Rocks.Texture of Lamprophyre is Porphyritic whereas that of Anorthosite is Foliated, Glassy. Lamprophyre appears Dull, Banded and Foilated and Anorthosite appears Layered, Banded, Veined and Shiny. The luster of Lamprophyre is subvitreous to dull while that of Anorthosite is pearly to subvitreous. Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, 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 Anorthosite are creating artwork, curling.
