What type of rock is a kimberlite pipe.

Jan 29, 2023 · Diatreme Facies Kimberlite: This type of kimberlite is formed as a result of explosive volcanic activity that creates a deep, cylindrical or funnel-shaped pipe called a diatreme. It is composed of fragmented country rocks and volcanic debris that are transported to the surface by violent gas explosions.

In addition, the kimberlite contained …Just beneath such volcanoes is a carrot-shaped "pipe" filled with volcanic rock, mantle fragments, and some embedded diamonds. The rock is called kimberlite after the city of Kimberley, South Africa, where the pipes were first discovered in the 1870s. Another rock that provides diamonds is lamproite.These kimberlite pipes are the most significant source of diamonds, yet it is estimated that only 1 in every 200 kimberlite pipes contain gem-quality diamonds.

Kimberlite is an igneous rock formed from the cooling of olivine-rich magma. The kimberlite matrix rock is classified as ultrabasic, meaning it doesn’t contain any quartz or feldspar. This ultrabasic magma develops in the earth’s mantle about 200 kilometers below the surface, where the olivine-rich rock peridotite occurs in large quantities.
