摘要
对河北省围场五道沟地区航磁异常进行了地面磁测,证实了该航磁异常的存在,同时圈定了地面磁异常范围。通过对地面磁异常的处理,将地面磁异常分为3个不同的区段,依据异常特征和磁化率参数,推测3个磁异常区段分别与晚太古代变质岩、中生代沉积岩和燕山晚期花岗斑岩体相对应,为矿床勘探提供了较为明确的地球物理依据。
surface magnetic survey was processed on air magnetic anomaly in Wudaogou area,Hebei Province Weichang Country.The surface magnetic anomalies were outlined and the air magnetic anomaly was approved.The surface magnetic anomalies were dived into three parts by the analysis.Based on the characateristics of surface magnetic anomalies and the Susceptibility,the three parts of surface magnetic anomalies were corresponded with Later Archean metamorphit,Mesozoic sedimentary rocks and Later Yanshan granitic porpyry.Geophysical foundations for mineral prospecting were put forward.
