The silicon isotope composition of biogenic silica (δ 30 Si BSi) in the ocean is a function of
the δ 30 Si of the available dissolved Si (DSi; H 2 SiO 4), the degree of utilisation of the …

In contrast to many other stable isotopes of the elements discussed in this book, those of
silicon are not strictly speaking “Non-Traditional Stable Isotopes” because they have been …

This study presents lithium, magnesium and silicon isotope ratios from pore waters and soils
from a well-characterised Histic Andosol in south-west Iceland. The soil δ7Li composition …

The Si isotopic composition of Earth's mantle is thought to be homogeneous (δ30Si=−
0.29±0.08‰, 2s. d.) and not greatly affected by partial melting and recycling. Previous …

Knowledge of the weathering processes controlling continental transfer of dissolved silicon
(DSi) to the ocean is fundamental to the estimate of the long-term atmospheric CO2-budget …

Thirty-five mafic and ultramafic rocks have been analysed for their silicon isotopic
composition to very high precision with the aim of providing a robust average value for the …

Silicon isotopic data from a range of lunar samples are presented to assess the degree of
heterogeneity of the lunar mantle and its similarity to bulk silicate Earth (BSE). Multi-collector …

High precision Si isotope ratios have been measured for a series of meteorites and
terrestrial samples using high-resolution multi-collector ICP-MS. Our results differ from those …

The Archaean continental crust comprises two major groups of silicon-rich granitoids: the
tonalite–trondhjemite–granodiorite and granite–monzonite–syenite suites, which differ in …

The silicon (Si) isotope compositions of 42 meteorite and terrestrial samples have been
determined using MC-ICPMS with the aim of resolving the current debate over their …
