文摘

A minimum chargeability can be derived from a thin sheet model of Airborne Induced Polarization Airborne IP effects are small and only detectable from sources in the top few tens of metres using helicopter EM systems Airborne IP effects are spatially coherent, and distinct from conductivity and magnetic susceptibility effects Ilmenite mineralisation shows strong IP effects
