摘要:
上宫金矿田处于华北板块南缘、熊耳山金多金属矿集区西部，具备良好的金成矿地质条件。干树金矿床为上宫金矿田内重要的中低温热液型金矿床。对干树金矿区 F1断裂深部开展了地质、物探、化探等综合勘查，以期获得找矿突破。采用音频大地电磁法测深（CSAMT）和钻孔原生晕地球化学分析相结合的方法，推断了F1断裂、矿化体产状及埋藏深度。通过钻孔验证，证实了深部存在 3层隐伏矿体，实现了该矿段深部找矿突破。勘查结果表明，综合找矿方法可以快速确定深部隐伏矿体，对同类型金矿的找矿勘查具有重要借鉴意义。

Abstract:
The Shanggong Gold Ore Field is located at the southern margin of the North China Plate and in thewestern part of the Xiong’ershan gold polymetallic province, characterized by favorable geological conditions forgold mineralization. The Ganshu Gold Deposit is an important hydrothermal gold deposit at low⁃to⁃medium temperaturewithin the Shanggong Gold Ore Field. Comprehensive exploration integrating geological, geophysical, and geochemicalprospecting methods was carried out to investigate the deep extension of the F1 fault in the Ganshu Gold Deposit,aiming to achieve breakthroughs in mineral exploration. By combining controlled⁃source audio⁃frequency magnetotellu⁃rics (CSAMT) with geochemical analysis of drillhole’s primary halos, the F1 fault, occurrence of the mineralized bodies,and burial depth were inferred. Drillhole verification confirmed the existence of 3 layers of concealed orebodies atdepth, achieving a significant prospecting breakthrough in the deep section of this deposit. The prospecting resultsdemonstrate that integrated prospecting methods can rapidly identify deep concealed orebodies, providing importantinsights for prospecting similar types of gold deposits.
