Genesis and evolution of kimberlites
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 …

Insights into kimberlite petrogenesis and mantle metasomatism from a review of the compositional zoning of olivine in kimberlites worldwide
A Giuliani - Lithos, 2018 - Elsevier
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 …

Geodynamics of kimberlites on a cooling Earth: Clues to plate tectonic evolution and deep volatile cycles
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 …

Kimberlite ascent by assimilation-fuelled buoyancy
Kimberlite magmas have the deepest origin of all terrestrial magmas and are exclusively
associated with cratons,,. During ascent, they travel through about 150 kilometres of cratonic …

Hafnium isotopic heterogeneity in zircons from granitic rocks: Geochemical evaluation and modeling of “zircon effect” in crustal anatexis
We carried out a geochemical evaluation and modeled the mechanism responsible for
varied Hf isotopic ratios in magmatic zircons of a single granitic rock specimen. Five …

Kimberlites as geochemical probes of Earth's mantle
DG Pearson, J Woodhead… - Elements: An …, 2019 - pubs.geoscienceworld.org
Kimberlites are ultrabasic, Si-undersaturated, low Al, low Na rocks rich in CO2 and H2O. The
distinctive geochemical character of kimberlite is strongly influenced by the nature of the …

Sources and mobility of carbonate melts beneath cratons, with implications for deep carbon cycling, metasomatism and rift initiation
Kimberlite and carbonatite magmas that intrude cratonic lithosphere are among the deepest
probes of the terrestrial carbon cycle. Their co-existence on thick continental shields is …

Rift-induced disruption of cratonic keels drives kimberlite volcanism
Kimberlites are volatile-rich, occasionally diamond-bearing magmas that have erupted
explosively at Earth's surface in the geologic past,–. These enigmatic magmas, originating …

Constraints on kimberlite ascent mechanisms revealed by phlogopite compositions in kimberlites and mantle xenoliths
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 …
