The Dahongshan copper-iron deposit, located in central Yunnan, is a quintessential example of copper and iron metallogenesis within the Kangdian copper-iron polymetallic metallogenic belt. This deposit is distinguished by its diverse co-associated elements, complex metallogenic processes, multi-phase tectonic composites, and multiple mineralization styles. The ore bodies are hosted within the shallow metamorphic volcanic-sedimentary rock system of the Paleoproterozoic boundary, with the accumulated reserves of iron and copper metals classified as super-large deposits. From shallow to deep incised fracture zones, the deposit exhibits widespread hydrothermal superposition-type copper-iron ore bodies (veins). However, the spatial distribution characteristics of these vein-like ore bodies and their tectonic control mechanisms remain poorly understood, and the ore-controlling tectonic system and its controlling process are not known. Based on the large-scale tectonic-alteration petrographic mapping at various scales and depths, coupled with detailed analysis of the tectonic geometry, kinematics, and mechanical properties of the hydrothermal vein ore bodies, this study elucidates the metallogenic tectonic system during the hydrothermal superposition period. The findings reveal that the metallogenic tectonic system during the hydrothermal superposition metallogenic period is the NE tectonic zone of the Chengjiang period, under the action of the NW-SE oriented main compressive stress, governs the distribution of ore deposit, ore bodies and veins. This tectonic framework forms a hierarchical control system, with different scales of tectonic assemblages influencing ore distribution. Specifically, the spatial distribution of the deposit is controlled by the Dibadu dorsal fold and its associated fracture and jointing rift systems. At the ore body (vein) scale, the distribution is regulated by 'multi-character' and 'in-character' tectonic assemblages. This research provides critical insights into the hydrothermal superposition mineralization processes and offers valuable guidance for ore exploration within the Kangdian copper-iron metallogenic belt.
