What is kimberlite.

Kimberlites are carbonate-rich volcanic rocks derived from low- degree melting of the mantle, which have a unique place in the Earth Sciences, because they represent the deepest sourced melts [>150 to 250 km; e.g., (12, )] and are the major host for diamonds. On their journey to the surface, kimberlite magmas entrain a rangePallasites are a rare type of meteorite. Only 61 are known to date, including 10 from Antarctica, with four being observed falls.

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 ...Kimberlites are silica-poor, MgO-rich and volatile-rich (CO 2 ± H 2 O) igneous rocks, which originate from the deeply derived magmas (>150-200 km; Pearson et al., 2014) that ascend rapidly to the surface (Mitchell, 1986; Sparks, 2013; Mitchell et al., 2019).
