摘要：

This paper demonstrates how to automatically obtain the location and depth of magnetic field sources of known structural index, such as contacts and dykes, for profile and map datasets. The method uses the analytic signal amplitude, and does not require that the magnetic data be pole-reduced or have a known magnetisation vector. The method is applied both to synthetic data and to aeromagnetic data from South Africa.
