- •
Two types of titanite exist in the Beiya deposit: magmatic titanite in porphyry and hydrothermal titanite in skarn.
- •
U–Pb age of hydrothermal titanite is 33.1 ± 1.0 Ma, restricting the mineralization age to 33.1–34.1 Ma.
- •
Ore fluid is magmatic in origin with relatively high oxygen fugacity.
- •
Magmatic and hydrothermal titanite can be discriminated by their textures and elemental distributions.
