The Depositional Record, EarlyView.The article demonstrates that brine was central for the supply of Ca and B to the studied saline lake. The ion transport occurred probably by thermal springs, while contributions from surface waters cannot be excluded. However, the saturation and syndepositional precipitation of Ca borates were initiated by an arid climate through evaporation, while ...
