For many decades the accurate and precise determination of isotope ratios has remained a
very strong interest to many researchers due to its important applications in earth …

The paper reviews geological, structural, mineralogical, fluid inclusion, geochemical and
stable isotope characteristics of U deposits related to Na-metasomatism in the Central …

We derive an estimate for the chemical composition of the depleted MORB mantle (DMM),
the source reservoir to mid-ocean ridge basalts (MORBs), which represents at least 30% the …

This paper presents the first comprehensive major and trace element data for∼ 130 abyssal
peridotite samples from the Pacific and Indian ocean ridge–transform systems. The data …

We present new analytical data of major and trace elements for the geological MPI‐DING
glasses KL2‐G, ML3B‐G, StHs6/80‐G, GOR128‐G, GOR132‐G, BM90/21‐G, T1‐G, and …

It has been assumed that Nb and Ta are not fractionated during differentiation processes on
terrestrial planets and that both elements are lithophile. High-precision measurements of …

Variations of high-field strength element (HFSE) ratios in terrestrial reservoirs, in particular
Zr/Hf and Nb/Ta, are critical for understanding crust–mantle differentiation. Growing …

Models explaining the characteristic depletion of High Field Strength Elements (HFSE)
relative to elements of similar compatibility in subduction zone magmas invoke either (1) the …

The present paper reports trace element concentrations of 15 elements (V, Cr, Fe, Zr, Nb,
Mo, Sn, Sb, Hf, Ta, W, Lu, Pb, Th and U) as well as Pb and Hf isotope data for four relatively …

It has been proposed that Archean tonalitic–trondhjemitic–granodioritic magmas (TTGs)
formed by melting of mafic crust at high pressures. The residual mineralogy of the TTGs …
