摘要:
青山金矿床位于柴北缘成矿带，具有较好的成矿潜力，但其地质特征的系统研究仍不完善，水文地质特征一直未被查清，阻碍了资源的进一步开发利用。矿区内共圈出SBⅠ号～SBⅤ号5 条破碎蚀变带，以 5 条破碎蚀变带为基础划分了 5 条矿带。其中，Ⅰ号矿带未发现矿（化）体，在Ⅱ～Ⅴ号矿带中圈定56条金、铅、金铅复合矿体，伴生银、锌。通过对区域水文地质特征、矿区水文地质特征、地下水类型及含水层，以及地下水的补给及径流等研究，确定了矿区含水层（组）分为5种主要类型，即松散岩类孔隙水、基岩裂隙水、块状岩类裂隙水、层状岩类裂隙水、碳酸盐岩类岩溶裂隙水。按水文地质复杂程度，青山金矿床的水文地质勘查类型属水文地质条件简单的基岩裂隙水充水矿床。研究结果可为同类型金矿床开发利用提供水文地质条件的理论支撑。

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.
