Abstract
Experiments on titanium partitioning between zircon and silicate melt were conducted at temperatures 1300 and 1400°С at 1 atm total pressure. Additionally, the Ti content in zircons of a few experimental series from (Borisov and Aranovich, 2019) was measured and a critical analysis of experimental literature was carried out. It was demonstrated that at high temperatures (1200–1450°С) 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 shown that “Ti in zircon” geothermometer cannot describe Ti content in our experimental zircons and, possibly, cannot be applied to dry high-titanium melts at 1 atm total pressure.
期刊介绍：
Petrology is a journal of magmatic, metamorphic, and experimental petrology, mineralogy, and geochemistry. The journal offers comprehensive information on all multidisciplinary aspects of theoretical, experimental, and applied petrology. By giving special consideration to studies on the petrography of different regions of the former Soviet Union, Petrology provides readers with a unique opportunity to refine their understanding of the geology of the vast territory of the Eurasian continent. The journal welcomes manuscripts from all countries in the English or Russian language.
