Editorial for Special Issue "Minerals of Kimberlites: An Insight into Petrogenesis and the Diamond Potential of Deep Mantle Magmas".

Kimberlites are igneous rocks that represent the deepest magmas originated from the mantle (>150 km) and typically occur within cratons. Kimberlites are hybrid rocks consisting of minerals of different origins: xenogenic minerals produced by the fragmentation of foreign mantle and crustal rocks (i.e., xenoliths and xenocrysts), primary minerals crystallized from kimberlite melt, and later minerals formed during the post-magmatic alteration of kimberlites. Garnet, chromite, ilmenite, chrome-diopside, and olivine serve as kimberlite indicator minerals because they occur in kimberlites in significantly higher quantities than diamonds. Influences of kimberlite-related melt preceding kimberlite eruption and transporting kimberlite melt caused the formation of a number of metasomatic phases in the eclogite.
