Polymineralic inclusions in kimberlite-hosted megacrysts: Implications for kimberlite melt evolution

Lithos, 2019
Abstract Megacrysts are large (cm to >20 cm in size) mantle-derived crystals, which are commonly entrained by kimberlite magmas, comprising of olivine, orthopyroxene, clinopyroxene, phlogopite, garnet, ilmenite and zircon as common phases. Numerous studies have shown megacrysts to contain polymineralic inclusions, which have been interpreted to ...

Kimberlite Volcanism

Annual Review of Earth and Planetary Sciences, 2013
Kimberlite magmas are volatile-rich, silica-poor ultrabasic magmas originating as small-degree mantle melts at depths of 150 km or greater. Alteration and entrained xenoliths obscure their original magma chemistry and properties.
