5 Formation

5.1 Formation

Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

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

All about Granulite and Lamprophyre Properties

Know all about Granulite and Lamprophyre properties here. All properties of rocks are important as they define the type of rock and its application. Granulite belongs to Metamorphic Rocks while Lamprophyre belongs to Igneous Rocks.Texture of Granulite is Granoblastic whereas that of Lamprophyre is Porphyritic. Granulite appears Veined or Pebbled and Lamprophyre appears Dull, Banded and Foilated. The luster of Granulite is vitreous while that of Lamprophyre is subvitreous to dull. Granulite is available in black, brown colors whereas Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. The commercial uses of Granulite are curling, gemstone, laboratory bench tops, soil conditioner, tombstones 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).
