Abstract Models test our understanding of processes and can reach beyond the spatial and
temporal scales of measurements. Multi-component Reactive Transport Models (RTMs) …

Silicon (Si) is the second‐most abundant element in the earth's crust. In the pedosphere,
however, huge spans of Si contents occur mainly caused by Si redistribution in soil profiles …

The nine editions of Stable Isotope Geochemistry have appeared over a time span of nearly
50 years. The first edition (1973) appeared as a slim book of 135 pages. Due to the rapid …

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 …

The terrestrial sediment record indicates that the Earth's climate varied drastically in the
Precambrian era (before 550 million years ago), ranging from surface temperatures similar …

In order to better understand the reactivity of plant phytoliths in soil solutions, we determined
the solubility, surface properties (electrophoretic mobilities and surface charge) and …

Soil is the primary source of plant silicon (Si) and therefore a key reservoir of the Si
biological cycling. Soil processes control the stock of Si‐bearing minerals and the release of …

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 (Li) and magnesium (Mg) isotope data from experiments
designed to assess the effects of dissolution of primary phases and the formation of …

Analysis of river water, rock, travertine and soil from the high altitude, negligible vegetation
setting of the Southern Tibetan Plateau demonstrates that Ca and Mg isotope ratios are …
