| Abstract: | The distribution of electrical conductivity beneath Shaanxi region has been studied by the single station Z/H method using Sq data recorded in the Shaanxi geomagnetic network. The results show that the apparent depth of the ideal substitute conductor is about 500 km and the conductivity 0.07 s/m for period 12 hr. There are the high conductive layers at 250 km and 700 km or so. |Q1| and |Q2| have a period change of 11 years. The results between the four stations of Shaanxi geomagnetic network are quite close each other and consistent with that obtained by the same and other methods in the most situations. The results from the Sq data of solstitial period is smoother than that from the Sq data of equinoctial period. When m=1, the results of single station Z/H method are obviously different from that of other methods, which indicate that the method is limited for the geomagnetic deep sounding research. |
