Authigenic carbonates recovered from two newly discovered active cold seeps on the
northwestern slope of the South China Sea have been studied using petrography …

An experimental study was conducted to determine oxygen and carbon isotope fractionation
factors in the system dolomite–water–CO 2 at 80–350 and 100–250° C, respectively, by …

Calcite growth experiments have been performed in the presence of aqueous Mg at 25° C
and 1bar pCO2 to quantify magnesium partition coefficient DMg=(Mg/Ca) solid (Mg/Ca) fluid …

Amorphous calcium phosphate (Ca 3 (PO 4) 2 xnH 2 O; n?=? 3–4.5; ACP) is a precursor
phase of the mineral hydroxyapatite (Ca 5 (PO 4) 3 (OH); HAP) that in natural settings occurs …

The calcium carbonate hexahydrate mineral ikaite (CaCO 3⋅ 6 H 2 O) has been
documented in aquatic environments at near-freezing temperatures. An increase of the …

Amorphous precursors are known to occur in the early stages of carbonate mineral
formation in both biotic and abiotic environments. Although the Mg content of amorphous …

This study assesses the potential use of Mg isotopes to trace Mg carbonate precipitation in
natural waters. Salda Lake (SW Turkey) was chosen for this study because it is one of the …

Carbonate clumped isotope thermometry is based on the thermodynamically dependent
relative abundance of 13 Csingle bond 18 O bonds (quantified as Δ 47) within the carbonate …

The formation of Mg-bearing calcite via an amorphous precursor is a poorly understood
process that is of relevance for biogenic and abiogenic carbonate precipitation. In order to …

Various marine calcifiers form exoskeletons via an amorphous calcium carbonate (ACC)
precursor phase and magnesium plays an important role in the temporary stabilization of …
