Thin sheet approximation of Earth’s conductive structures made it possible to quantitatively estimate effects of lateral conductivity variations in the Earth long before full 3-D electromagnetic modeling was practicable. The thin sheet approach is still useful when induction data with limited vertical resolution are to be interpreted on a surface. It especially refers to collections of long period induction arrows across large areas and geological units. For this purpose, inverse procedures, both linearized and stochatic, for a conductance distribution in a thin sheet have been suggested recently. We present a stochastic Monte Carlo inversion of geomagnetic induction data based on the bayesian formulation of the inverse problem.
