文摘
- •
We propose a two-epoch metallogenetic model for the Cuihongshan deposit.
- •
The Fe mineralization was related to the alkali-feldspar granite.
- •
The Pb–Zn (Cu) and W–Mo mineralization were associated with the syenogranite.
- •
The Fe mineralization took place at about 491.1 ± 2.4 Ma.
- •
The Pb–Zn (Cu) and W–Mo mineralization occurred at about 198.0 – 202.1 Ma.
