Reconstructing ocean pH with boron isotopes in foraminifera
In order to better understand the effect of CO2 on the Earth system in the future, geologists
may look to CO2-induced environmental change in Earth's past. Here we describe how CO2 …

Effect of growth rate and pH on lithium incorporation in calcite
Carbonates are only a minor sink of oceanic lithium, yet the presence of this element and its
abundance relative to other metal cations in natural carbonate minerals is routinely used as …

Zinc isotope fractionation during the inorganic precipitation of calcite–Towards a new pH proxy
Zinc was co-precipitated with calcite in mixed-flow reactors at 25° C and 6.1≤ pH≤ 8.5 to
quantify Zn isotope fractionation between calcite and the reactive fluid. The results suggest …
