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.

Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.

All about Lamprophyre and Hawaiite Properties

Know all about Lamprophyre and Hawaiite properties here. All properties of rocks are important as they define the type of rock and its application. Lamprophyre and Hawaiite belong to Igneous Rocks.Texture of Lamprophyre is Porphyritic whereas that of Hawaiite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular. Lamprophyre appears Dull, Banded and Foilated and Hawaiite appears Dull and Soft. The luster of Lamprophyre is subvitreous to dull while that of Hawaiite is not available. Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Hawaiite is available in black, brown, light to dark grey 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 Hawaiite are creating artwork, sea defence.
