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 …

A comprehensive, internally consistent U-Pb and Lu-Hf isotope data set for 93 mantle-
derived zircons from the Yakutian kimberlite province confirms and further refines the four …

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

The discovery of radioactivity in the early 20 th century led to the development of several
radiometric dating methods (eg, Rb-Sr, Sm-Nd, Re-Os, U-Pb, etc.). These radiometric dating …

The subequatorial Angolan continental margin offers excellent conditions to test textbook
theories on the composition of passive-margin sediments generated in different climatic and …

Despite their economic and scientific significance, the tectonic drivers that lead to the
genesis of kimberlites and related rocks remain enigmatic. The presence of any spatio …

Age-progressive volcanism is generally accepted as the surface expression of deep-rooted
mantle plumes, which are enigmatically linked with the African and Pacific large low–shear …

Magnesian ilmenite is a common kimberlite indicator mineral, although its use in diamond
exploration is still controversial. Complex crystallisation and replacement processes have …

Kimberlites are the surface manifestation of deeply-derived (> 150 km) and rapidly
ascended magmas. Fresh kimberlite rocks are exceptionally rare, as most of them are …

The compositions (mineralogy, major-and trace-element chemistry of rocks and minerals,
and Sr-Nd-Hf isotope systematics) of two kimberlite bodies, the Obnazhennaya pipe and the …
