- •
The Hongshi granitoids are shoshonitic, derived from melting of juvenile lower crust mixed with mantle components.
- •
The magmatism might have occurred at ca. 337–334 Ma, indicating that the Hongshi gold deposit is younger than 334 Ma.
- •
The predominant sources of the ore fluids and metals at Hongshi are host rocks with some discernable magmatic sources.
- •
The Hongshi deposit is an orogenic-type system, and the granitoids played a key role in controlling the gold mineralization.
