Insight from AIP modelling of VTEM ET data from Colorado

Summary

Portions of the VTEM ET dataset from the Upper East River survey in Colorado were strongly affected by airborne induced polarization (AIP) effects. Ignoring AIP contributions to the data leads to difficulties in geological interpretation and loss of information. Undertaking full IP modelling in the inversions produces a 3D description of the Cole-Cole parameters that yields more robust and complete result. Preliminary estimates of apparent chargeability display significant differences compared with the full inverted chargeability.
