| Abstract: | Lake Qarun is an inland saline lake of the type Na---(Mg)---Cl---(SO4). The SO4/Cl weight ratio exceeds 0.6. The sequence of salt deposition, upon mechanical evaporation at 70°C, starts with basanite and halite, passes with magnesium sulphate minerals and ends with sylvite and carnallite. High concentrations of Sr in the gypsiferous fraction and B in the end-residue are recorded. |
