摘要
针对辽北铁矿的分布特点及赋存规律,全面分析了辽宁省抚顺县毛公铁矿的地质、物探资料,从成矿地质环境及磁异常特征着手,论述了该区铁矿的找矿远景。通过与邻区矿床地质特征对比,认为毛公铁矿体在空间上为一个铁矿层,并首次采用深钻对低缓磁异常区进行了工程验证,在孔深359～620m处发现厚度大、埋藏深、规模大、品位高的隐伏鞍山式铁矿,表明该区具有深部找矿的巨大潜力。这对今后在辽北地区开展第二轮深部找矿,提高铁矿床技术经济价值都具有非常重要的意义。
According to the distribution feature and occurrence law of the iron deposits in north of Liaoning province, the geological and geophysical prospecting information of Maogong iron deposit in Fushun, Liaoning were analyzed. Starting with the geological environment and magnetic anomaly features, the ore prospecting potential was discussed. Through the comparison of geological characteristics of the deposit and the adjacent area deposits, it is thought that Maogong iron ore body is one iron bed in space. The engineering verification was carried out by using deep drilling on weak magnetic anomaly area in the first time, and it was found that concealed Anshan type iron deposit with large thickness, deep burial, large scale and high grade in the hole depth of 359 620m. It indicated the deep prospecting potential. It is important to carry out the second round prospecting in deep and improve the economic benefit.
