“…As for the last record from the "red" list of Table 2, we have no a priori information about the presence of power lines or other overhead metallic constructions in the survey area, but the latter is known to be relatively flat, so a reasonable geological explanation for an elevated conducting body could hardly exist anyway. The obtained results show that application of the above search algorithm to the whole onshore MT/ BBMT database of Nord-West Ltd., which includes thousands of records taken in complex geological conditions and extremely rugged topography (e.g., those acquired in Sub-Andean fold belt-see Palshin et al 2020) has not yield a single impedance tensor, which could be confidently regarded as being non-causal due to geological reasons. This allows concluding that, though the potential existence of non-causal impedances (and hence magnetic tensors, tippers and any other transfer functions formally treating the horizontal magnetic field as an input-see Part I) on the land surface should not be excluded completely, the actual chance to encounter such data in practice is negligible.…”

“…Usually, MTS is used in applied geophysics for prospecting and deep investigations of the sedimentary cover and consolidated crust for large areas [20] and for other environmental purposes. The modern MTS application is close to studying tectonic disturbances in rock masses.…”

“…The MT method has relatively good accuracy in predicting the depth and thickness of the subsurface layers, including the underlying basement and possibly structures that are generally more difficult to identify. The MT method can resolve complex structures in volcanic or limestone-covered and overthrust belt areas, where the seismic method is problematic (Patro, 2020;Xu et al, 2020;Palshin et al, 2020). The MT 2D modeling results are interpreted to infer the subsurface geology of the study area, more particularly to delineate layer boundaries and the basement based on the resistivity models.…”
