Abstract: The Qingshan Gold Deposit, located in the Northern Qaidam Margin metallogenic belt, exhibits significant mineralization potential. However, systematic studies on its geological features and unclear hydrogeological characteristies have hindered further resource exploitation. 5 fractured alteration zones (SBI to SBV) have been delineated in the mining area, corresponding to 5 ore zones. While no ore (mineralized) bodies were found in Zone I, 56 gold, lead, and gold-lead composite orebodies (with associated silver and zinc) were identified in Zones II -V. Through regional and local hydrogeological investigations, including groundwater types, aquifers, recharge, and flow patterns, the aquifers in the deposit were classified into 5 main categories: loose rock pore water, bedrock fissure water, massive rock fissure water, layered rock fissure water, and carbonate karst-fissure water. Based on hydrogeological complexity, the Qingshan Gold Deposit is categorized as a bedrock fissure water-filled deposit with simple hydrogeological conditions. These findings provide theoretical support for hydrogeological assessments in similar gold deposits.
