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

All about Lamprophyre and Latite Properties
Know all about Lamprophyre and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Lamprophyre and Latite belong to Igneous Rocks.Texture of Lamprophyre is Porphyritic whereas that of Latite is Aphanitic to Porphyritic. Lamprophyre appears Dull, Banded and Foilated and Latite appears Rough. The luster of Lamprophyre and Latite is subvitreous to dull. Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Latite is available in black, brown, green, grey, pink, white colors. The commercial uses of Lamprophyre and Latite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
