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 …

Silicon (Si) released as H 4 SiO 4 by weathering of Si-containing solid phases is partly
recycled through vegetation before its land-to-rivers transfer. By accumulating in terrestrial …

Biomineralization is a widespread strategy for augmenting robustness, and material
strength, and for co** with high concentrations of toxic minerals. Prominent examples for …

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 …

Background Silicon and aluminium oxides make the bulk of agricultural soils. Plants absorb
dissolved silicon as silicic acid into their bodies through their roots. The silicic acid moves …

The bananas are thought to be particularly sensitive to changes in the environment. This
review considers some historical and recent investigations into the response of the leaf, root …

Three Si isotope materials have been used for an inter-laboratory comparison exercise to
ensure reproducibility between international laboratories investigating natural Si isotope …

This study presents the Si isotope compositions of the dissolved phase of twenty rivers from
across Iceland. The high-resolution Nu Plasma 1700 MC-ICP-MS was used to provide …

The quantification of silicon isotopic fractionation by biotic and abiotic processes contributes
to the understanding of the Si continental cycle. In soils, light Si isotopes are selectively …

Two higher plant species (rye grass and clover) were cultivated under laboratory conditions
on two substrates (solution, phlogopite) in order to constrain the corresponding Mg isotope …
