| 中文摘要: |
| 文章通过对内蒙古自治区中部达茂旗一带进行的1∶5万高精度航空磁测资料的深入分析和研究，以达茂旗大苏吉—四子王旗赛忽洞多金属找矿研究区4个航磁异常的地面查证为例，采用综合物探方法，对异常的地质矿产特征、地球物理特征进行综合分析，认为蒙C-1967-160号和蒙C-2013-175号异常为沉积变质型磁铁矿引起；激电异常较为明显的蒙C-1967-170号和蒙C-2013-118号异常可作为找寻多金属矿的线索；对幅值较低、不明显的弱小磁异常也应作为进一步找矿的线索。研究表明，高精度航空磁测资料结合地面异常查证在指导寻找铁及多金属矿产方面具有重要作用。 |

| High-precision aeromagnetic survey data at scale 1:50 000 in the Damaoqi area in the central part of Inner Mongolia Autonomous Region are detaily analyzed and researched and the integrated geophysical prospecting method is applied to make ground check on 4 aeromagnetic anomalies in Dasuji-Saihudong polymetallic prospecting research area. Integrated analysis of cahracteristics of geology, mineral resources and geophysics show that anomly C-1967-160 and C-2013-175 is possibly caused by esdimentary-metamorphic iron ore and IP anomly C-1967-170 and C-2013-118 should be considered as the clue for polymetallic prospecting and weak anomly with low amplitutde value also the clue. High precision aeromagnetic survey data and ground check based on regional geological and mineral resources is an important tool to guide iron ore and polymetallic mineral resources prospecting. |
