摘要
利用新一轮高精度航空物探的成果,从航磁的角度系统对西拉木伦河中段的区域地质构造、深大断裂和构造岩浆岩进行了研究。详细地介绍了研究区的区域磁场特征、西拉木伦河断裂带、大兴安岭主脊断裂以及华北地台北侧的构造岩浆岩低侵带的基本特征,揭示了一定的地球物理反映的深部地质信息。总结了区内已知的多金属矿(点)集区的地质~地球物理特征,该结果能够为该地区进一步基础地质研究工作提供参考。
Based on the new-round high-precision airborne geophysical at the middle of Xilamulun river,the regional tectonics,deep faults and tectonic magmatic rocks were systematic studied.In this paper,the authors analyzed deeply regional magnetic characteristics,in the Xilamulun river fault zone,Daxinanling main ridge fracture and the low-invased tectonic-magmatic belt structural feature at the north side of north china platform.The deep geological information has been revealed.Furthermore,in this paper,the authors generalized geological-geophysical characteristics of known pool of multi-metal mine(points)in this area.All of those could be offer some reference for further deep space prospecting.
