摘要
The partition coefficients (K-D) 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 alpha Mg/alpha Ca of the ambient waters. Strongly alkaline and very high alpha Mg/alpha Ca (>>20) waters cause the partition coefficients of ostracodes to differ significantly from those found in other lakes with lower alpha Mg/alpha Ca values. Water salinity does not affect the uptake of Mg or Sr in ostracode valves, whereas the alpha HCO3- of the water strongly correlates to K-D[Sr], with high aHCO(3)(-) resulting in a significant K-D[Sr] decrease.
