摘要:
南杂木金矿床地处辽东的抚顺一清原金铜成矿带内，其内矿产资源丰富，金矿床（点）密布，地质找矿前景良好，但受森林覆盖率高的限制，找矿突破难度大。鉴于此，以南杂木金矿床为研究对象，基于矿体与围岩的激电特性差异，采用大功率激电面积测量和激电测深工作圈定矿致异常。基于激电测量工作成果，在矿区内圈定激电异常5处，并在DJ-2号激电异常处探获矿体1条，该矿体控制长200 m，中部水|平厚度最大，为3.1m，平均金品位2.39 g/t。研究成果表明，大功率激电法在南杂木金矿床勘查中找矿效果较好，可为进一步找矿工作提供理论基础和实践依据。

Abstract:
The Nanzamu Gold Deposit is located within the Fushun-Qingyuan Au-Cu metallogenic belt in Eastern Liaoning, an area rich in mineral resources and densely distributed with gold deposits (spots), offering excellent pros-pecting potential. However, the high forest coverage poses challenges for significant breakthroughs in exploration. To address this, the study focused on the Nanzamu Gold Deposit, employing high-power induced polarization (IP) area measurement and IP sounding techniques to delineate ore-induced anomalies based on the IP property differ-ences between the orebody and surrounding rocks. From the results of the IP survey, 5 anomalies were identified within the mining area. Among them, a single orebody was discovered in the DJ-2 IP anomaly zone. The orebody spans 200 min length, with a maximum horizontal thickness of 3.1 min the central part and an average gold grade of 2.39 g/t. The findings indicate that the high-power IP method achieves promising results in the exploration of the Nanzamu Gold Deposit, providing both theoretical and practical support for future prospecting efforts.
