Kimberlites are volcanic rocks enriched in CO2 and H2O and derive from the deepest-
sourced melts (up to 300 km) that reach Earth's surface. The mantle processes that generate …

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 …

The minerals constituting the Earth's upper mantle are nominally anhydrous silicates
(NAMs). However they do contain hydrogen as a trace element, decorating point defects in …

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 …

We report new data on the geochemical evolution, metasomatic and deformation processes
in the lower layers of cratonic lithospheric mantle based on a detailed study of …

We present petrographic, major element and trace element data for bulk-rocks and minerals
for a suite of 34 remarkably fresh peridotite xenoliths in the Udachnaya kimberlite recovered …

Kimberlite magmas are of economic and scientific importance because they represent the
major host to diamonds and are probably the deepest magmas from continental regions. In …

Olivine is the dominant component in kimberlites (~ 40–60 vol%), where it occurs as
individual grains of variable size (> 1 cm to< 100 μm) of xenocrystic and magmatic origin …

Kimberlites represent magmas derived from great mantle depths and are the principal
source of diamonds. Kimberlites and their xenolith cargo have been extremely useful for …

Quantifying the compositional evolution of mantle-derived melts from source to surface is
fundamental for constraining the nature of primary melts and deep Earth composition …
