Geology Today
Kimberlites, while relatively rare, are perhaps the most interesting of igneous rocks and have accordingly attracted attention disproportionate to their abundance. They are the source of most diamonds and bring us direct sampling of Earth’s mantle (otherwise only available indirectly by geophysical methods).

Kimberlite Magmatism and Textural Genetic Classifications of Kimberlite
1986Initial studies of kimberlites (Wagner 1914) demonstrated that they occur as carrot-shaped vertical intrusions termed pipes or diatremes and as tabular dikes (fissure kimberlites).

Abstract Kimberlites are ultramafic rocks in which H 2 O, CO 2 and the residual elements K, Rb, Cs, Sr, Ba, U, Th, Nb, etc., are strongly concentrated. It is proposed that their restriction to continental shield areas is genetically significant in that these are the areas with the lowest geothermal gradients. In this environment, magmas form at very

КІМБЕРЛІ́Т – вивержена магматична мало поширена гірська порода чорнього кольору з синім або зеленим відтінками. Складається переважно з олівіну, піроксенів, гранатів, флюгопіту, рідше – циркону, апатиту та ін. Виповнює т. зв. трубки вибухів газів у земній корі, алмазоносний.

Investigation of the geochemistry of kimberlite is hampered by problems inherent in the intrusive styles characteristic of this volatile-rich magma; by the hybrid nature of the rocks formed from magmas which carry a high proportion of crystalline phases at their time of emplacement; and by the high probability of contamination of some facies by crustal
