摘　　要：为了满足国家重点工程在沧州东部沿海地区基岩选址需求,该文基于该区域火山岩及其磁性特征,结合1∶10万无人机高精度航磁测量技术对火山岩分布进行研究。通过对比研究多方法数据处理结果,针对实测航磁数据先利用剩余异常开展解析信号、正则化倾斜角处理大致圈定工作区中玄武岩、火山岩的范围,最后结合磁场特征圈定火山通道。结果表明,在小山地区有6片玄武岩、香坊地区有6片强磁性玄武岩区和多片中等磁性火山岩区,且香坊地区的火山通道为长轴北东向展布的椭圆状,中间为强磁性火山岩。In order to meet the site selection needs of key national projects in the eastern coastal area of Cangzhou,this paper studied the distribution of volcanic rocks based on volcanic rocks and their magnetic characteristics in the area,combined with 1:100,000 drone high-precision aeromagnetic measurement technology.By comparing and studying the data processing results of multiple methods,based on the measured aeromagnetic data,the remaining anomalies are used to analyze the signals and regularize the tilt angle processing to roughly delineate the range of basalt and volcanic rocks in the work area,and finally the volcanic channel is delineated based on the characteristics of the magnetic field.The results show that there are 6 basalt sheets in the Xiaoshan area,6 strong magnetic basalt sheets and multiple isomagnetic volcanic rock sheets in the Xiangfang area,and the volcanic channel in the Xiangfang area is elliptical with its long axis spreading in the northeast direction,with strong magnetic volcanic rocks in the middle.
