In kimberlite pipes, the eruption ejects a column of overlying material directly over the magma column, and does not form a large above-ground elevation as typical volcanoes do; instead, a low ring of ejecta known as a tuff ring forms around a bowl-shaped depression over the subterranean column of magma. Over time, the tuff ...

Most kimberlite rocks contain large proportions of ellipsoidal-shaped xenocrystic olivine grains that are de- rived mainly from disaggregation of peridotite.

May 8, 2018 · Kimberlites contain abundant xenoliths derived from the mantle and, as such, they are extremely useful for investigating mantle mineralogy and chemistry. Many of the mantle-derived xenoliths have been brought up from such great depth that they contain high-pressure minerals, the best known being diamond , the high-pressure form of carbon. KimberLite is the worlds first cryptocurrency that is designed specifically for buying and selling precious commodities such as Diamonds and Gold, providing exceptional stability.

Kimberlite Event Space was designed & inspired by a kimberlite, an igneous rock that produces un-cut diamonds found in Kimberley, South Africa. Olivine crystals (green) are in a fine-grained matrix made up of clay minerals and carbonates (presented in blue, purple and buff colors). Kimberlite is an igneous rock and a rare variant of peridotite. It is most commonly known to be the main host matrix for diamonds. Unless a diamond is weathered out of kimberlite, kimberlite eruption will produce the last visible resorption effects, as it is the last event affecting the diamond before it reaches Earth’s surface. Features produced by the kimberlite will overprint or even remove those features produced in the mantle.Kimberlite eruptions are gas-powered explosive events. The magmas originate at depths of 150 to 450 km, deeper than other igneous rocks. Most kimberlites are in small vertical columns called kimberlite pipes although some rare sills are known.

The 3-021 kimberlite is located 1 kmnortheast of P-11 kimberlite and 3.5 km WSW ofP-10 kimberlite. The 3-008 kimberlite is located 1.8km east of P-10 kimberlite and is interpreted tocomprise a series of narrow kimberlite stringers.

A kimberlite magma can start at depths as great as 200–300 km, but must be generated at least below the depths where diamonds are stable (greater than 140 km) in order to pick them up from their lithospheric source. The source of kimberlite, either within or below the lithosphere, is a matter of active debate in the geologic co mmunity.

Kimberlite Pipes ...Kimberlite formation is a complex process involving magma rising quickly through the Earth’s mantle, carrying fragments of rock and minerals from deep within. As this magma reaches the surface, it explodes, creating an impact crater known as a maar. Kimberlite formation is unique due to its explosive nature.1. Kimberlite Rocks. The rocks are a type of igneous rock that forms when magma flows out of deep earth fractures.
