Kimberlite is an igneous rock, which sometimes contains diamonds. …

The kimberlite magmas at Diavik intruded 55 million years ago and are thus much younger than the Archean craton. The kimberlites are the transporting mechanism for the much older diamonds and indicator minerals that formed deep within the mantle of the craton. These diamonds are xenocrysts in the kimberlite, as are the indicator minerals.Kimberlite is an igneous rock best known for sometimes containing diamonds. It is named after the town of Kimberley in South Africa, where the discovery of an 83.5-carat diamond in 1871 spawned a diamond rush, eventually creating the Big Hole. Kimberlite occurs in the Earth's crust in vertical structures known as kimberlite pipes as well as ...Monomineralic millimeter-sized olivine nodules are common in kimberlites worldwide. It is generally thought that such 'dunitic nodules' originate from the base of the cratonic lithosphere and that their formation marks the onset of deep-rooted kimberlite magmatic plumbing systems. However, thermobarometric constraints to support such a model have been lacking thus far. This study focuses ...Indeed, although kimberlites originate from depths below the diamond window, not all kimberlite bodies have economic grades of diamond 82,83.
