Abstract
It has been found, on the basis of SSC and geomagnetic bays variations, that there is zone of a nearly vanishingZ component in the east-west trend along the Lanzhou-Xi’an-Zhengzhou zone, and it is called the Lanzhou-Xi’an-Zhengzhou anomalous zone of electrical conductivity. There are some relationships between the goelogical and geophysical characteristics along this zone. It is deduced that the zone may be a zone of weakened crust or a boundary between two sub-plates and it is also deduced that this zone is probably related to channelling effects of induced currents in a large region.
