Magnetotelluric Investigations of the tamar lineament

Memet Rachmat Hermanto - Nama Orang;

The magnetotelluric method is a geophysical technique which provides information about the deep electrical conduktivity distribution within the earth beneath the site of the surface field measurements. This method responds to one of the basic physical properties of rocks and minerals-conductivity, which in most rocks, is determined by the path of ionic conduction (e.g. porosity, pore fluid salinity) or by paths of electronic conduction (e.g. carbon on grain boundaries and metallic minerals), or in extreme cases, by high temperature or partial melting. The method makes use of the temporal variations of the natural electromagnetic fields which originate outside the earth. These oscillating fields contain a wide spectrum of frequencies. The electromagnetic variations which are most suitable as a source field are those that are associated with magnetic storms or substorms. The current system that generates these variations is concentrated in the auroral zone and flows either through the temperate region ionosphere, or the magnetosphere (Parkinson, 1983). Electric fields produced by such variations cause eddy currents to flow in the earth.
