Diamond is not a common rock-forming mineral (an exception being “diamondite”; see
Jacob and Mikhail 2022, this volume) nor a common crustal mineral (the exceptions being …

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 …

Kimberlite magmatism has occurred in cratonic regions on every continent. The global age
distribution suggests that this form of mantle melting has been more prominent after 1.2 Ga …

Kimberlites are rare, enigmatic, low-volume igneous rocks. They are highly enriched in
magnesium, volatiles (CO2 and H2O) and incompatible trace elements and are thought to …

The petrogenesis of kimberlites is commonly obscured by interaction with hydrothermal
fluids, including deuteric (late-magmatic) and/or groundwater components. To provide new …

Olivine xenocrysts are ubiquitous in kimberlite deposits worldwide and derive from the
disaggregation of mantle-derived peridotitic xenoliths. Here, we provide descriptions of …

Earth's carbon cycle is strongly influenced by subduction of sedimentary material into the
mantle. The composition of the sedimentary subduction flux has changed considerably over …

Mantle-derived xenoliths entrained by low viscosity magmas indicate transport through great
thicknesses of orogenic (≲ 50-80 km) and cratonic (≲ 20 km) mantle lithosphere. The size …

The purpose of this article is to provide an overview of academic research on volcanic
geomorphology, through the use of bibliometric analysis and bibliographic visualization …

The composition of primary kimberlite melts and, in particular, the absolute and relative
abundances of volatile components (mainly CO 2 and H 2 O) are controversial issues …
