An outstanding feature of the Archaean Eon is that it was a time of major production and
preservation of continental lithosphere. Here I review the geological, geochemical and basic …

Cratonic lithospheric mantle is composed of predominantly refractory materials that formed
at higher mantle potential temperatures (TP) than recorded in non-cratonic peridotites. It also …

Treating messenger RNA transcript abundances as quantitative traits and mapping gene
expression quantitative trait loci for these traits has been pursued in gene-specific ways …

The highly siderophile elements (HSE) pose a challenge for planetary geochemistry. They
are normally strongly partitioned into metal relative to silicate. Consequently, planetary core …

The accretion of volatile-rich material from the outer Solar System represents a crucial
prerequisite for Earth to develop oceans and become a habitable planet,,–. However, the …

Core formation should have stripped the terrestrial, lunar, and martian mantles of highly
siderophile elements (HSEs). Instead, each world has disparate, yet elevated HSE …

New Os isotope and highly siderophile element (HSE) abundance data, in combination with
lithophile trace element and Sm–Nd, Lu–Hf, and Hf–W isotope data, are reported for …

Komatiites are ancient volcanic rocks, mostly over 2.7 billion years old (from the Archaean
era), that formed through high degrees of partial melting of the mantle and therefore provide …

Thirty-three whole-rock drill core samples and thirteen olivine, chromite, and sulfide
separates from three differentiated komatiite lava flows at Alexo and Pyke Hill, Canada, were …

Hotspot volcanic rocks are formed under conditions that differ from conventional plate
tectonic boundary magmatic processes and are compositionally distinct from mid-oceanic …
