Abstract:
The induced polarization (IP) response in airborne electromagnetic data has recently received attention due to its potential significance for mineral exploration and environmental applications, while also holding the prospect of improved geophysical models. A typical IP response produces negative transients in the late time gates. However, under certain circumstances, the presence of overly steep decays in themselves indicate the presence of chargeable material in the subsurface, i.e. where the chargeability is not strong enough to reverse the sign above the noise level, although it still decreases the signal.
