Abstract

The experiments on titanium partitioning between zircon and silicate melt were conducted at temperatures 1300 and 1400°C at 1 atm total pressure. Additionally, Ti content in zircons of a few experimental series from (Borisov, Aranovich, 2019) was measured and a critical analysis of experimental literature was carried out. It was demonstrated that at high temperatures (1200–1450°C) DTi values lie in the range from 0.02 to 0.04 regardless of pressure, melt composition, and water content. Based on obtained data, the impossibility of zircon crystallization from high temperature basic melts once more was shown. It was demonstrated that geothermometer “Ti in zircon” cannot describe Ti content in our experimental zircons and, possibly, cannot be applied to dry high-titanium melts at 1 atm total pressure.
