electrical conductivity anomalies

Crustal conductors and asthenosphere in the Carpathian region

Carpathian electrical conductivity anomaly (CEA) is traced by construction and analysis of induction vectors from which maximum possible depth (20-25 km) and integral conductance (about 108 Sm×m) were estimated. The true depth is determined by sounding methods: MTS over the axis of CEA was performed in only two areas in which properties of the AEC were different. Electric asthenosphere in Pannonian Basin begins at smaller depth (50-100 km) than on platforms (100-250 km), but results are not accurate, sometimes contradictory.
