Abstract

Electrical anisotropy measurements at high temperatures and quasi-hydrostatic pressures on previously deformed olivine plus melt samples show that electrical conductivity is much higher in the direction of deformation; this is confirmed with a layered electrical model of the asthenosphere and lithosphere that reproduces existing field data.
