摘　　要：通过对黑龙江省中南部已知铁及多金属矿床地质背景、航磁特征的梳理分析,总结了该区铁及多金属矿床的航磁特征,归纳了利用航磁资料,辅以地质、其他物化探资料快速甄别矿致航磁异常的方法。通过该方法优选航磁异常,为该区快速寻找铁及多金属矿产提供了找矿线索。通过近年来的实践验证,该方法具有较好的实用效果,为该区实现快速找矿突破提供了依据。Through the analysis of geological background and aeromagnetic characteristics of the known iron and polymetallic ore deposits in the middle-south of Heilongjiang Province,aeromagnetic characteristics of those deposits are summarized. The method for distinguish rapidly ore anomalies,using aeromagnetic data,geology and other geophysical-geochemical data,was concluded.Using the method to screen aeromagnetica nomaly,provide clues for rapidly finding iron and polymetallic ore deposits. Through the practice in recent years,this method achieved better practical results,and provides a basis for the rapidly prospecting in the area.
