The biogeochemical cycling of metals in natural systems is often accompanied by stable
isotope fractionation which can now be measured due to recent analytical advances. In …

This chapter reviews the state of art of the use of boron isotopes to understand water-rock
interaction in the Critical Zone, the thin and reactive layer at the Earth's surface. Because …

Mineral dissolution rates control the temporal evolution of many natural processes on the
surface and upper crust of the Earth. This is the first of a series of papers describing the …

Biotite dissolution rates were determined at 25° C, at pH 2–6, and as a function of mineral
composition, grain size, and aqueous organic ligand concentration. Rates were measured …

Boron isotopes in marine carbonates are increasingly used to reconstruct seawater pH and
atmospheric pCO2 through Earth's history. While isotope ratio measurements from individual …

Lithium (Li) isotopes have been shown to be fractionated significantly during chemical
weathering of silicate rocks. However, previous research has mainly been focused on basalt …

Contributions of geothermal reservoir and aquifer rock weathering to dissolved arsenic (As)
concentrations remain poorly understood. This study investigated geochemical and isotopic …

The evolution of atmospheric CO 2 and the pH of the ocean can be reconstructed by the
boron isotopic composition (δ 11 B) of marine carbonates, which is influenced by the δ 11 B …

Large-scale ab initio Meta-Dynamics simulations were applied to elucidate the molecular
mechanism and reaction free energies of pyrophyllite dissolution at the (1 1 0) edge surface …

To which extent does the apparent negative correlation reported between silicate
weathering rates and time result from the spontaneous physicochemical evolution of the …
