The partition coefficients (KD) guiding the uptake of Mg and Sr in the low-Mg calcite valves of ostracodes in Australian saline lakes have been reviewed in line with new information on the bicarbonate content and the Œ±Mg/Œ±Ca of the ambient waters. Strongly alkaline and very high Œ±Mg/Œ±Ca (>>20) waters cause the partition coefficients of ostracodes to differ significantly from those found in other lakes with lower Œ±Mg/Œ±Ca values. Water salinity does not affect the uptake of Mg or Sr in ostracode valves, whereas the Œ±HCO3‚Äì of the water strongly correlates to KD[Sr], with high Œ±HCO3‚Äì resulting in a significant KD[Sr] decrease.
