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.
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles
Origin
Kimberley, South Africa
European Foreland Basins
Discoverer

Arnold H. Bouma
Etymology
From Kimberley + -ite, from the name of the South African town of Kimberley where the rock was first found.
From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939

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.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

All about Kimberlite and Turbidite Properties
Know all about Kimberlite and Turbidite properties here. All properties of rocks are important as they define the type of rock and its application. Kimberlite belongs to Igneous Rocks while Turbidite belongs to Sedimentary Rocks.Texture of Kimberlite is Porphyritic whereas that of Turbidite is Mud-rich, Sandy. Kimberlite appears Dull and Banded and Turbidite appears Dull and Banded. The luster of Kimberlite is subvitreous to dull while that of Turbidite is metallic. Kimberlite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Turbidite is available in black, brown, green, grey, pink colors. The commercial uses of Kimberlite 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 Turbidite are cemetery markers, creating artwork.
