Figure 1: Anisotropic conductivity models obtained from inversion of electromagnetic data in different geological contexts. Here we report the results of laboratory experiments at asthenospheric ...

Electrical conductivity experiments use four to eight tungsten wires, magnetic susceptibility experiments require a microloop of about ten turns of wire, and high-temperature experiments use eight ...
