- •
The underlying causes of variation in ablation behaviour between different zircon matrices are investigated.
- •
Ablation rates are found to be directly proportional to the degree of structural distortions present in a zircon matrix.
- •
Radiation damage is the dominant factor controlling the ablation rate for moderate to highly metamict zircon samples.
