Mg isotopic composition of carbonate: insight from speleothem formation
TL;DR: In this paper, high-precision measurement of 24 Mg, 25 Mg and 26 Mg isotopic compositions were made by multiple collector inductively coupled mass spectrometry (MC-ICP-MS) relative to the international standard SRM980.

Cyanobacterial tufa calcification in two freshwater streams: ambient environment, chemical thresholds and biological processes
Martina Merz-Preiß,Robert Riding +1 more
TL;DR: In this paper, the authors investigated the environmental limits to cyanobacterial calcification in fast-flowing streams and found that cyanobacteria preferentially utilize bicarbonate and sheath impregnation by calcium carbonate even where the annual WATEQ4F Saturation Index exceeds 0.8.

Geochemistry and the understanding of ground-water systems
Pierre D. Glynn,L. Niel Plummer +1 more
TL;DR: In this paper, a thermodynamic perspective is offered that could facilitate the comparison and understanding of the multiple physical, chemical, and biological processes affecting ground-water systems, and the best approach will ensure an optimized iterative process between field data collection and analysis, interpretation and the application of forward, inverse, and statistical modeling tools.

Dissolution kinetics of calcium carbonate minerals in H2OCO2 solutions in turbulent flow: The role of the diffusion boundary layer and the slow reaction H2O + CO2 → H+ + HCO3−
Zaihua Liu,Wolfgang Dreybrod +1 more
TL;DR: In this paper, a rotating disk technique was used to investigate the effect of the DBL on the dissolution rates of CaCO 3, which allowed an exact adjustment of the thickness of the diffusion boundary layer by controlling the rotation speed of a circular sample of Ca CO 3.

The kinetics of calcite dissolution and precipitation in geologically relevant situations of karst areas: 2. Closed system☆
TL;DR: In this article, a general theory of dissolution and precipitation rates at CaCO3 surfaces from calcareous solutions in contact with an atmosphere containing CO2 is presented, where three rate-determining processes, kinetics at the Ca CO3 surface, diffusion into the bulk and conversion of CO2 into HCO−3 are treated simultaneously.
