Gravity and magnetic modelling of anomalous sources of complex configuration.

The automated fitting method was applied to the modelling of gravity and magnetic anomalies. This technique allows us to use for interpretation the observed components of gravity and magnetic fields and their linear transformations, the geoid anomalies, and the course gradient data of magnetic fields. The software is based on the optimization of the sum of square differences between measured and modelled field components. The universal approximation procedure for parametrization of anomalous sources allows us to describe effectively different elements of the modelled space. The optimization procedure for the minimization of objective functions includes gradient-based algorithms and singular value decomposition technique. The technology is tested on practical geological problems. [ABSTRACT FROM AUTHOR]
