| Zusammenfassung |
| Zircon was grown from Nb and Ta doped hydrous felsic melts in piston-cylinder experiments at 1GPa and 800–1300℃. Zircon and glass were present in all run products. Concentrations obtained through in-situ analysis of zircon crystals and melt were used to calculate Nb and Ta partition coefficients Dzircon/melt. The changes of portioning coefficients between zircons and melts with temperature are LnDNbzircon/melt=-5.2611+ 4250.3(1/T) for Nb and LnDTazircon/melt =-3.2738+2977.3(1/T) for Ta.
