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 …

Olivine, and the origin of kimberlite
Two types of olivine occur in kimberlites from Greenland, Canada and southern Africa. The
first, xenocrystic olivine, displays several different forms. Most distinctive are 'nodules', a term …
