- •
Optimal conditions for chemical abrasion of single zircons are annealing at 900 °C for 48 h and leaching at 190 °C for 15 h.
- •
Leaching at a lower temperature does not completely remove Pb loss.
- •
Annealing at higher temperature might restore crystallinity in zones that were affected by Pb loss.
