As the Mossbauer spectra of minerals often have very broad resonant lines a new method of Mossbauer spectra resolution is investigated. New method allows with a help of a mathematical procedure to transform the initial experimental spectrum to its N-spectrum. Each spectral component in the derived N-spectrum narrows appreciably, retaining its position and relative intensity. In common with a quadrupole splitting distribution analyses this method allows to decompose the experimental spectrum on its partial components more accurately.
