Definition
Kimberlite is a rare, blue-tinged, coarse-grained intrusive igneous rock, which sometimes contains diamonds and is mostly found in South Africa and Siberia.
Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture
Origin
Kimberley, South Africa

Etymology
From Kimberley + -ite, from the name of the South African town of Kimberley where the rock was first found.

Archaeological Significance
Formation
Kimberlite is an igneous rock and is the main source of diamonds. Its formation takes place deep beneath the Earth’s surface between 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 Kimberlite and Latite Properties
Know all about Kimberlite and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Kimberlite and Latite belong to Igneous Rocks.Texture of Kimberlite is Porphyritic whereas that of Latite is Aphanitic to Porphyritic. Kimberlite appears Dull and Banded and Latite appears Rough. The luster of Kimberlite and Latite is subvitreous to dull. Kimberlite 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 Kimberlite 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).
