The Jianchaling giant Au deposit is hosted by a fault in the MLY area, Qinling Orogen.
- •
The deposit was characterized by low-salinity and CO2-rich fluids.
- •
Fuchsite Ar
Ar dating constrained the Au mineralization to ~ 200 Ma.- •
The Jianchaling is an orogenic gold deposit, and formed during continental collision.
- •
The beginning of the continental collision between the Yangtze and the North China cratons took place ~ 200 Ma.
