Nature of crustal and mantel conductors

© Gordienko V.V.

Probable mechanisms of large (with S of more than the first thousands of Sm) crustal and mantle conductors are considered. Regional crustal anomalies of electrical conductivity are due to:

  • zones of high graphite concentration (n1%)
  • zones of fluid concentration (0,5-5%)
  • fluid (about 0,5%) and graphite (n0,1%) containing zones

The mantle anomalies are due to the partial melting strata (n1% of melt).
