| Abstract: | A method is described for measurement of the magnetic viscosity of rocks, which is considered in its three forms: induced magnetization viscosity, remanent magnetization viscosity and viscous remanent magnetization. An application is then presented in the form of an experimental verification of the E. and O. Thellier test of approximate elimination of the viscous magnetization effect in rocks. It is shown that, used in the conventional manner, the employment of this test is fully justified, although not allowing measurement of the VRM, the values obtained being seriously underestimated. |
