摘    要:磁异常是寻找铁磁性矿产的重要依据,航磁测量发现的磁异常需要通过地面查证以评价其找矿意义。笔者采用地面高精度磁测、土壤地球化学测量及地质剖面草测相联合的方法对黑龙江齐齐哈尔黑C-2016-0001号航磁异常进行地面查证,发现磁异常正负变化部位与Cu、Mo、Au化探异常叠合较好,反演结果显示在岩性变化部位有磁性体。结合区域地质资料、岩矿石物性特征、异常反演结果综合分析,推断该异常可能由大理岩与花岗岩接触部位的矽卡岩型铁-多金属矿引起,值得进一步开展验证工作。

关 键 词:铁多金属矿  航磁异常  矽卡岩型  反演  黑龙江

Abstract:Magnetic anomaly is an important basis for finding ferromagnetic minerals. The magnetic anomalies found in aeromagnetic survey needs to be verified on the ground to evaluate its prospecting significance. In this paper, high-precision magnetic survey, soil geochemical survey and geological profile survey are used to verify the aeromagnetic anomalies of Hei-C-2016-0001 on the ground. It is found that the positive and negative changes of magnetic anomalies are well overlapped with Cu, Mo and Au geochemical anomalies, and the inversion results show that there are magnetic bodies in the changes of lithology. Combined with the comprehensive analysis of regional geological data, physical properties of rocks and ores, and the inversion results of the anomalies, it is concluded that the anomalies may be caused by skarn type iron polymetallic ore in the contact part of marble and granite, which is worth further verification.
Keywords:iron polymetallic deposit  aeromagnetic anomaly  skarn type  inversion  Heilongjiang Province
