Abstract:

The electrical conductivity of the earth appears to pass through a minimum value at moderate depths, probably between 10 and 20 kilometers. At lesser depths, rocks contain sufficient water-filled void space to be moderately conductive, and at greater depths, increased temperatures again render rocks conductive. The problem of determining the conductivity in this minimum zone is a difficult one. A possible solution lies in the use of electromagnetic coupling measurements for studying this zone in the crust.
