Abstract
The effects of the content of alkalis on zircon solubility in multicomponent model silicate melts was experimentally studied within the temperature range of 1300–1400°C and 1 atm total pressure. It was demonstrated that the addition of Na2O and K2O to the melt results in a comparable increase in zircon solubility. The advantages and disadvantages of the parameters describing the effects of the melt composition on zircon solubility are briefly discussed.
