What is kimberlite.

Kimberlite is an igneous rock that major source of diamonds. Kimberlite is a variety of peridotite . It is rich in mica minerals content and often in form of crystals of phlogopite. Other containt abundant minerals are chrome-diopside, olivine, and chromium- and pyrope-rich garnet .kimberlite, is the lamproite. Lamproite pipes are created in a similar manner to kimberlite pipes, except that boiling water and volatile compounds contained in the magma act corrosively on the overlying rock, resulting in a broader cone of eviscerated rock at the surface.

Hypabyssal kimberlites are subvolcanic intrusive rocks crystallised from mantle-derived magmas poor in SiO2 and rich in CO2 and H2O. They are complex, hybrid rocks containing significant amounts of mantle-derived fragments, primarily olivine with rare diamonds, set in a matrix of essentially magmatic origin.

Kimberlites magmas rise from depth through narrow ~1m thick fissures. The kimberlite magma is focused along structural faults which act as focuses for waters or resultant brecciation due to volatile exsolution from the rising kimberlites may act as a focus for water. The brecciated rock becomes recharged with groundwater.
