本文从频率域分析了陕西近年来记到的约十个地磁湾扰和磁扰。结果表明,渭河南北的垂直分量位相相反,水平分量也存在异常,源场极化方向和异常幅度有一走关系,同相和异相感应矢量指向渭河方向,这些都说明感应电流从渭河地堑下集中流过。据此推测在地壳下部或地幔上部存在一高导体。结合邻区地磁湾扰和其它短周期异常认为,这个高导体可向东西延伸上千公里长。
In this paper, the frequency domain analysis of about ten recorded in recent years in Shaanxi Bay magnetic interference and magnetic interference. The results show that the vertical components of the Weihe River are opposite in phase and the horizontal components are anomalous. The polarization direction of the source field has a one-way relationship with the anomalous amplitude. The in-phase and out-phase induction vectors point to the Weihe direction. All of these show that the induction current is concentrated from Weihe graben flow past. It is presumed that there is a high conductor in the lower part of the crust or in the upper part of the mantle. In conjunction with the geomagnetic bays and other short-period anomalies in the adjacent area, this high conductor can extend for thousands of kilometers from east to west.
