Magnetic‐survey data in grid form may be interpreted rapidly for source positions and depths by deconvolution using Euler’s homogeneity relation. The method employs gradients either measured or calculated. Data need not be pole‐reduced so that remanence is not an interfering factor. Geologic constraints are imposed by use of a structural index. Model studies show that
