文摘
- •
A sediment-hosted Nb-Zr-REE-Ga mineralization in SW China was described.
- •
The mineralization was initially derived from Emeishan alkaline volcanic ashes.
- •
The alkaline volcanic ashes were altered by subsequent hydrothermal fluids.
- •
A critical element-enrichment model has been proposed for this Nb-Zr-REE-Ga deposit.
- •
The mineralization has giant economic potential.
