文摘

•: 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 ArAr 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.
