Abstract Knowledge of the elemental compositions and isotopic ratios of geological samples
is a prerequisite for geochemical research. For whole-rock elemental composition and …

The highly siderophile elements (HSE) consist of the Platinum Group Elements (PGE: Ru,
Rh, Pd, Os, Ir, Pt) along with rhenium and gold. These transition elements show relative …

We quantify the behavior of Cu, Ga, Ge, As, Mo, Ag, Cd, In, Sn, Sb, W, Tl, Pb, and Bi during
the differentiation of a picritic magma in the Kilauea Iki lava lake, Hawaii, using whole rock …

The origin of Earth's volatiles has been attributed to a late addition of meteoritic material after
core–mantle differentiation. The nature and consequences of this 'late veneer'are debated …

Ultramafic xenoliths from southeastern Arizona, USA, provide evidence for Cu‐isotope
heterogeneity in the lithospheric mantle. We report new data on Type I (Cr‐, Mg‐rich) …

BACKGROUND Through the 1980s, much of the information obtained regarding mantle
composition and its inherent heterogeneity was derived through indirect evidence, ie, the …

The Kerguelen large igneous province (LIP) has been related to mantle plume activity since
at least 120 Ma. There are some older (147–130 Ma) magmatic provinces on circum-eastern …

High precision nickel stable isotopic compositions (δ 60/58 Ni) are reported for 22 peridotite
xenoliths from the USA (Kilbourne Hole, New Mexico), Tanzania, and Cameroon. For a …

The selenium stable isotope system emerges as a new potential tracer of volatile origin and
evolution of the terrestrial planets. Accurate determination of the mantle Se isotope …

ABSTRACT Peridotites from the Tonga Trench are some of the deepest-derived and freshest
ever obtained from the seafloor. This study reports new bulk-rock major-, trace-, highly …
