The MRT system is effectively a resistivity imaging system, having been designed to provide information from which the distribution of subsurface resistivity in crosssection along a profile can be determined. It is of particular value in are as where the strata show both lateral and vertical variation in electrical properties. The field technique involves making repeated constant-separation apparent resistivity traverses along the chosen profile, the spacing being incremented at each pass.
