The strata exposed in the mining area mainly consist of the Middle Permian Fanjiatun Formation and Quaternary floodplain deposits. The Fanjiatun Formation is dominated by silty slate, carbonaceous slate, phyllite, and two-mica quartz schist that displays local mylonitization. Among these lithologies, silty slate and two-mica quartz schist constitute the principal ore-hosting rocks. Intrusive rocks exposed in the mining area are dominated by monzogranite and granodiorite, with local mylonitization observed in the monzogranite. A small rhyolite porphyry dike occurs near Orebody No. I. Both plutonic rocks and dikes are closely associated with gold mineralization.
The orebodies consist of 13 gold-bearing quartz veins, which are hosted in the silty slate and two-mica quartz schist of the Middle Permian Fanjiatun Formation and are strongly controlled by NW- and NNE-trending faults. Among these, Orebody No. I is the largest. It strikes at 60°, dips at 70–80°, and has a thickness ranging from 1.0 to 14.6 m (average 7.8 m). The orebody remains open along the strike, and the gold grades range from 0.8 to 7.79 g/t (average 4.26 g/t).
Three principal ore types are quartz vein-type, altered rock-type, and micro-vein-type ores. Quartz vein-type ores display granular textures with disseminated and vein structures. Altered rock-type ores are characterized mainly by metasomatic and granular textures and exhibit vein, stockwork, and massive structures. Micro-vein-type ores occur as streaky or disseminated aggregates along micro-cleavages and fractures in slate.
The mineralization process of the Ailinwudui gold deposit can be divided into five stages: Pre-ore stage; Quartz–pyrite stage; Polymetallic sulfide stage; Post-ore stage; Surface oxidation stage.
