5.1 Formation

Epidosite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

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

All about Epidosite and Lamprophyre Properties

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