摘　　要：湖北省大冶市许家咀铜铁矿区位于铜绿山矿田的西北部,在近年的找矿工作中取得重大进展,新发现了3个工业矿体群,其中Ⅲ号矿体为主矿体,铜资源量达到近中型规模。在找矿过程中,收集了1:1万平面重磁数据、钻孔原生晕数据,开展了物探CSAMT电法剖面及测井工作。本文系统总结了区内岩矿石物性特征、平面重磁异常特征、基岩地球化学异常特征,矿体元素组合特征。在上述研究成果的基础上,对平面重磁、CSAMT、三分量磁测井、钻孔原生晕成果进行了更加深入的数据处理以及异常提取,同时结合地质情况进行综合研究,提出有利的找矿部位,开展找矿预测。分析认为,在矿区东南深部接触带以及北西部矿体倾向有较好的找矿潜力,有效的指导了下一步找矿工作。Xujiazui copper and iron mining area of Daye City,Hubei Province is located in the northwest of T onglushan ore field,In recent years,T hree new industrial ore bodies were discovered,It was a great progress in prospecting for ore.theⅢore body is the main ore body and copper resources reached near-medium size.In the process of prospecting,We collected 1:1 million area gravity and magnetic data and primary halo anomalies data.The C SAMT electrical profiling and logging of geophysical exploration have been carried out.This paper systematically summarizes the physical characteristics of rock ore in the area and plane gravity and magnetic anomaly characteristics and geochemical anomaly characteristics of bedrock and element combination characteristics of ore body.On the basis of the above research results,We have carried out more in-depth data processing and anomaly extraction on the results of planar gravity and magnetic logging,C SAMT,three-component magnetic logging and drilling initial halo.At the same time,We conducted a comprehensive study in conjunction with geological conditions,We proposed a favourable site for prospecting and carry out prospecting prediction.The analysis shows that there is good prospecting potential in the southeast deep contact zone and the vergence direction of the north west ore body.It effectively guides the next step of prospecting work.
