Abstract

A computer programme for two dimensional magnetometric resistivity modelling is described. The electric potential is calculated by the finite difference method1 and from the resulting current distribution the magnetic field response is obtained by an integration through the two dimensional conductivity plane. The current sources and receiver points can be specified anywhere (not restricted to the two dimensional conductivity plane). Several sources can be specified at once. Solutions (single-source) for all specified sources are obtained simultaneously. Computed results are compared to analytical solutions for three conductivity models: the uniform conductivity model, the contact model and the multi-layer model. Instructions for running the programme are provided.
