- •
The Hujiayu Cu deposit is a Paleoproterozoic metamorphogenic Cu deposit.
- •
The host rocks underwent ~ 550 °C metamorphism revealed by graphite geothermometry.
- •
The discordant thick vein type Cu mineralization formed during retrograde cooling.
- •
The selenium fugacity markedly increased after major chalcopyrite precipitation.
- •
Chalcopyrite Re
Os dating showed that Cu mineralization occurred at ~ 1952 Ma.
