中文摘要:
      测区位于智利海岸山带铁氧化物铜金成矿带、阿塔卡玛断裂系统上。该地区地表覆盖厚,残坡积沙土及碎石层发育。为了有效提高地质找矿成果,采用地面高精度磁测与地质联合检查异常的找矿方法,通过对磁异常特征的综合分析和钻探对异常进行验证,在磁异常区发现了磁铁矿,进一步圈定出找矿有利地段,取得了良好的找矿效果。
英文摘要:
      The magnetic survey area is located in the coastline iron oxide copper-gold mineralization belt and Atacama fault system in Chile. The surface area is covered by thick colluvial sandy soil and gravel layer. In order to improve the geological prospecting effect, the combination approach of ground high-precision magnetic survey and geological mapping was conducted. Based on the comprehensive analysis of magnetic anomaly and test drilling results on the magnetic anomalies, the magnetite orebody was discovered. Further, the favorable prospecting targets were delineated. 
