ELECTROMAGNETIC RESPONSE OF ABNORMAL BODY IN 3-D BELOW A CAP ROCK BY VERTICAL MAGNETIC DIPOLE

Li Shouchun Li Chunxiang Zhang Bojun (Changchun Univ of Earth Sciences, Changchun 130026)  
The authors of this paper have computeried the electromagnetic field by vertical magnetic dipole under the condition of 3-D body and covering in a half space below the ground The results have showed that the effect of cap rock is decreased when σ 1 is close to σ 2, it is increased when σ 1 is increased, and the amplitudes of field at high frequency ( f ≥2 KHz) and low frequency ( f ≤10 Hz) all are decreased obviously at the different σ 2/σ 1, and the amplitude is maximum at 2 KHz≥ f ≥10 Hz, and the fields by vertical magnetic dipole can distinguish obviously rock characters and beds
