Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

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 …

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 …

Analysis of organic and inorganic carbon (DOC and DIC, respectively), pH, Na, K, Ca, Mg,
Cl, SO 4 and Si in~ 100 large and small rivers (< 10 to≤ 150 000 km 2) of western Siberia …

When rock is converted to weathering products, the involved processes can be fingerprinted
using the stable isotope ratios of metals (for example Li, Mg, Ca, Fe, Sr) and metalloids (B …

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 …

Silicon (Si) is the second most abundant element in the Earth's crust and is an important
nutrient in the ocean. The global Si cycle plays a critical role in regulating primary …

The relevance of biological Si cycling for dissolved silica (DSi) export from terrestrial
biogeosystems is still in debate. Even in systems showing a high content of weatherable …

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 …
