I observe to dense confusions about MMR for some geonvs.Thus,I established clear informations👍
I observe to caused a confusion cond by some geoenvs of Magnetometric Resistivity chapter.Thus,I needed to some clear explanations.
We can classify by two main branch Magnetometric Resistivity applications considering actualtimes;
- Landsurvey concept(Modern example is Willowstick Technique)
- Downhole concept(DMMR)
Note.I emhasize especially expressed selective a cond to needs of some geoenvs based on geologic structures of presentation👍

Where,as evaluated,understanding clearly selective roles of IPRF-2 frequency domain IP Receiver with MFM-3 high sensitivity vector fluxgate magnetometer for MIP😐
You are right,the magnetic induced polarization (MIP) method determines the variation of the induced polarization and resistivity of the earth through measurements of the magnetic field associated with galvanic current flow in the earth, rather than the electric field, as in the traditional induced polarization (IP) or electrical induced polarization (EIP) method👍
Important differences between the MIP and EIP methods are evident in field practice, mathematical theory, and field results. For example, the MIP method is insensitive to horizontal layering in the earth and reflects only lateral variations in its electrical properties. MIP also provides an enhanced ability to detect the presence of bodies of anomalous electrical properties even through a highly conducting surface layer. For this reason the MIP methods primary application is in regions of highly conducting (e.g., saline) overburden or weathered rock, such as in Australia. MIP responses tend to be more complex and varied in pattern than responses normally encountered in EIP measurements. For example, polarity reversals are the rule in MIP but are rarely encountered in EIP. MIP employs high-sensitivity component magnetometers as basic sensors. These are small relative to the length of the electric dipole sensors normally employed in EIP, and, therefore, provide relatively higher geometric resolving power👍
