5.1 Formation

Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

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

All about Basanite and Lamprophyre Properties

Know all about Basanite and Lamprophyre properties here. All properties of rocks are important as they define the type of rock and its application. Basanite and Lamprophyre belong to Igneous Rocks.Texture of Basanite is Aphanitic to Porphyritic whereas that of Lamprophyre is Porphyritic. Basanite appears Glassy or Pearly and Lamprophyre appears Dull, Banded and Foilated. The luster of Basanite is waxy and dull while that of Lamprophyre is subvitreous to dull. Basanite is available in black, brown, green, grey, red, white colors whereas Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. The commercial uses of Basanite are as a touchstone, creating artwork, gemstone, in fire-starting tools, manufacture of tools, metallurgical flux, jewelry, to ignite fire, used in flintlock firearms 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).
