Around 600 out of 6000 known types of kimberlite pipes contain diamonds. What does a Kimberlite Pipe Look Like? Kimberlite often looks like a cylinder in its pipe form. The morphology of kimberlite pipes is varied, but includes a sheeted dyke complex of tabular, vertically dipping feeder dykes in the root of the pipe, which extends down to the mantle. Within 1.5–2 km (0.93–1.24 mi) of the surface, the highly pressured magma explodes upwards and expands to form a conical to cylindrical diatreme , which ...One of the most common rocks found at the park is also one of the rarest to find beyond the borders of the crater. Lamproite is the volcanic material that erupted from the park’s diamond-bearing pipe around 100 million years ago. Four types of lamproite can be found at the park today, but not all are diamond-bearing.

This specimen is from the Finsch Diamond Mine in South Africa. Let's get started! Introduction Kimberlite, a gas-rich potassic ultramafic igneous rock, is a primary source of diamond on earth. First found in Kimberley in Africa, this stone inherits its name from the place. Let us find out more about kimberlites in this article today. We shall discuss the following topics: What is KimberliteThe meaning of Kimberlite is stability. Kimberlite was called Diamond Rock in earlier times due to the presence of Diamonds. The presence of other crystals in it also earned names like Peridotite Diamond and Olivinite Diamond. Today, this Diamond-Bearing Rock is used for clarity, vitality, grounding, karmic healing, and transformation.The volcanic rock type found in these pipes is called kimberlite, named for its type area of Kimberley, South Africa.

Kimberlite itself is an igneous rock, and is considered a rare variant of peridotite. Those who are familiar with the formation of peridot know that peridotite is an olivine-rich stone that bears the semi-precious gemstone peridot. When the kimberlite or lamproite reaches the surface, the sudden release of magmatic gas and interaction with groundwater causes explosions, producing pipe-shaped diatremes filled with fragmented kimberlite and country rock.
