| Abstract/Notes | The Huajian gold deposit (>30 t Au at ∼9.2 g/t) is a typical intrusion-related gold deposit in the northern margin gold belt of the North China Craton (NCC), China. The gold mineralization displays a pronounced spatial correlation with the Niuxinshan high heat production (HHP) granites with highly evolved characteristics, but their genetic linkage remains unresolved, including precise ore-forming ages of the Huajian gold deposit, especially quartz vein-type gold mineralization distal from granitic pluton. A combination of detailed deposit geology, zircon LA-ICP-MS U–Pb and muscovite 40Ar/39Ar dating and in-situ zircon Hf isotopes was conducted in this study. At least two distinct mineralization events, including early-stage veinlet-disseminated and vein-type gold mineralization formed in 173–170 Ma and late-stage vein-type ores (e.g., EW-striking) in 167–165 Ma, were identified in the Huajian gold deposit. These episodic mineralization events exhibit temporal and spatial correspondence with multi-phase magmatic intrusions (∼174, 170, and 167 Ma) accompanied by extensive hydrothermal exsolution from the Niuxinshan HHP granitic suite and associated aplite, likely representing the culminating fractionation stage of a protracted magmatic system. These highly evolved magmas are suggested to stem from a thermally buffered crustal magma reservoir. Isotopic evidence confirms that this reservoir was episodically replenished by melts originating from metasomatized lower crustal sources with mantle affinity, as demonstrated by varied zircon εHf(t) signatures, e.g., εHf (t) = −4.3 to −13.6 and −8.6 to −14.2 for granitic aplite and fine-grained granites, respectively. The close temporal-spatial agreements and volatile exsolution textures in these evolved granites corroborate their causative role, establishing Huajian as a prime example of gold mineralization driven by the HHP granites. These findings highlight the genetic links between gold mineralization and HHP granites characterized by high evolution, offering crucial insights for regional gold exploration strategies in the NCC. |
