International audience; Komatiites are crystallized samples of high-temperature, high-MgO lavas that were common during the Archean, but became increasingly rarer in the Proterozoic and Phanerozoic. Although the origin of komatiites remains a subject

Globally distributed kimberlites with broadly chondritic initial (143)Nd-(176)Hf isotopic systematics may be derived from a chemically homogenous, relatively primitive mantle source that remained isolated from the convecting mantle for much of the Ea

Examination of the least-contaminated rocks of the Jurassic Karoo flood basalt province indicates considerable compositional variability in the mantle source. New and previously published Sr, Nd, and Pb isotopic data are suggestive of two main catego

Neodymium-142 isotope data from young Reunion Island volcanic rocks reflect the effects of geological processes that occurred more than four billion years ago, showing that the deep mantle may preserve geochemical signatures of the primordial Earth.
