Investigation of the possibilities of potential fields structural transformations in geological mapping

The main aim of the research is investigation of the possibilities of geological objects formalized localization based on magnetic and gravitational fields lineament analysis.

The computational experiment was carried out in several stages. At the first stage on simple models, the features of the appearance of the geological structure in potential fields transformations were studied. On the second stage, to create a complex regional background, additional density objects that are imitating fault tectonics were added to the model. On the third, the effect of random noise on the results of field transformation was evaluated.

As a result of mathematical calculations for the synthetic magnetic and gravitational fields, the efficiency of the proposed lineament analysis for geological mapping is shown. The proposed method of lineament analysis allows to confidently outline geological objects even in low-contrast potential fields. It is suggested to carry out preliminary smoothing of the original fields to increase the effectiveness of lineament analysis in the presence of random noise.
