Silicon isotope variations accompanying basalt weathering in Iceland
TL;DR: In this article, the Si isotope compositions of twenty rivers from across Iceland were used to provide interference-free 30Si/28Si ratios with an average limiting precision of ± 0.04 δ30Si.

Silicon isotopes in meteorites and planetary core formation
TL;DR: In this paper, the silicon isotope compositions of 42 meteorite and terrestrial samples have been determined using MC-ICPMS with the aim of resolving the current debate over their compositions and the implications for core formation.

TL;DR: In this article, the authors present hafnium and neodymium isotopic compositions and concentrations in surface waters of the eastern Atlantic Ocean between the coast of Spain and South-Africa.

Iron and silicon isotope behaviour accompanying weathering in Icelandic soils, and the implications for iron export from peatlands
Sophie Opfergelt,Sophie Opfergelt,Helen M. Williams,Helen M. Williams,Jean-Thomas Cornélis,Jean-Thomas Cornélis,R.A Guicharnaud,R. B. Georg,R. B. Georg,Christopher Siebert,Christopher Siebert,Sigurdur R. Gislason,Alison Halliday,Kevin W. Burton,Kevin W. Burton +14 more
TL;DR: In this paper, the authors used Fe isotopes to assess the processes controlling Fe export in a range of Icelandic soils including peat soils derived from the same parent basalt, where Fe isotope variations principally reflect differences in weathering and drainage.

TL;DR: In this article, the Si-isotopic compositions of 7 chondrules and 3 CAIs from the CV chondrites Mokoia and Grosnaja were measured using the Nu Plasma MC-ICP-MS at the University of Oxford.
