A typical orogenic gold deposit located in the Jiao–Liao–Ji belt, North China Craton.
Metamorphic fluid was the initial ore-forming fluid for the Nancha deposit.
Boiling and mixing of fluids controlled the mineralization process.
Metallogenic materials sourced from Proterozoic rocks and ore-forming metamorphic fluids.
Gold mineralization occurred during Middle Jurassic accretionary orogen regime.
