Kimberlites are thought to rise through a series of fissures in the rock.Kimberlites are igneous rocks that represent the deepest magmas originated from the mantle (> 150 km) and typically occur within cratons. Studies of kimberlites ...Kimberlite is a type of rock best known for sometimes containing diamonds. It is named after the town of Kimberley in South Africa, where the finding of a large kimberlite pipe in the 1870s spawned a diamond rush. Kimberlite has in many ways attracted more attention than its relative volume might suggest that it deserves.Kimberlite deposits are commonly highly altered, contain abundant xenoliths and xenocrysts from both mantle and crustal sources, and are likely partially or wholly degassed. Further, their great depths of origin make it very likely that the melt composition, temperature and volatile content vary with depth due to assimilation, crystallization ...Adam Abersteiner is a Postdoctoral Researcher at the University of Helsinki (Finland). He earned his PhD in geology from the University of Tasmania (Australia) in 2020. His work has largely been centred on reconstructing the petrogenesis of kimberlites and the composition of their original melt using various geochemical and melt inclusion techniques.Real kimberlite photo provided by and available for purchase at AuroraRocksScotland. Kimberlite is a type of rock from a very deep place in the Earth. It forms in the Earth’s mantle, the thick rock layer between the crust and the core. Magma, which is hot molten rock, rises through cracks in the mantle and reaches the surface.Muskox and Jericho kimberlites are located in the north-central portion of the Slave craton of the northwestern Canadian shield. Jericho is located ∼1 km from the north western tip of Contwoyto Lake, and Muskox is located ∼15 km SW of Jericho (Fig. 1).There are ∼15 other kimberlites within ∼50 km of these pipes and together they likely represent a Jurassic period of kimberlite ...kimberlite A brecciated (see BRECCIA), potassic, ultrabasic igneous rock, consisting of megacrysts of olivine, enstatite, Cr-rich diopside, phlogopite, pyropealmandine garnet, and Mg-rich ilmenite, in a fine-grained groundmass of serpentine, phlogopite, carbonates, perovskite, and chlorite, in varying proportions.Kimberlites contain abundant xenoliths derived from the mantle and, as such, they ...Kimberlites result from low-degree melting, also at great depth, of sources rich in incompatible elements and CO 2 + H 2 O. They become further enriched through interaction with overlying asthenospheric or lithospheric mantle. Boninites form by hydrous melting of metasomatized mantle above a subduction zone.

There are more than 160 known occurrences of kimberlite in many parts of the country. The Man Shield underlying the large parts of central and western Liberia host numerous kimberlite dikes, some of which are known to be diamondiferous.Kimberlite is a type of igneous rock. It forms from the cooling of magma like other igneous rocks, but is unique because it forms over 100 miles (150 kilometers) beneath the Earth’s surface and, in a matter of hours, travels to the top. It is also unique because it is one of two types of rock, along with lamproite, in which diamonds are found.The origin of alkali carbonates and chlorides in the groundmass of unaltered Udachnaya-East kimberlites in Siberia is still controversial. Contrary to existing dogma that the Udachnaya-East kimberlite was either contaminated by the crustal sediments or platform brines, magmatic origin of the groundmass assemblage has been proposed on the basis of melt immiscibility textures, melt inclusion ...Kimberlite. Type of igneous rock formed deep in the earth's mantle that extrudes as [pipe%]s that sometimes produce Diamond s. < Back.The answer lies in some of the oddest and rarest volcanoes on the planet.
