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 (n×1%)
- zones of fluid concentration (0,5-5%)
- fluid (about 0,5%) and graphite (n×0,1%) containing zones
The mantle anomalies are due to the partial melting strata (n×1% of melt).
