[BBC03-P04] Verification of ice-mineralization process: formation of authigenic carbonates in alkaline lakes during freezing condition in south Mongolia.
Keywords:carbonate, alkaline lake, mineralization
Freezing of lake water causes the increase of the ion concentrations because almost most of the ions are excluded from ice to solution. Inland closed lakes don’t have inflow and outflow rivers of which situation is almost same with evaporation. Therefore, the mineralization can be also caused by freezing process.
In this study, we have examined “ice-mineralization” process in the alkaline lakes from the observations of water chemistry from summer to winter in Mongolia.
