Anomalous changes in concentrations due to scattering halos are often comparable in their parameters with fluctuations of the geochemical background and with its changes due to the change of rocks. In these cases, it is necessary to use such a method of processing the survey results, in which the geochemical background, carrying information about the geological structure or regional geochemical patterns, is distinguished from the field of measured concentrations, and local anomalies of prospecting interest are identified

Based on the theoretical analysis of the distribution of element concentrations in the residual scattering halos of vein-shaped ore bodies, R. I. Dubov proposed to interpret the halos using specially calculated and constructed in semi-logarithmic scale palettes of theoretical curves. Interpretation with the help of palettes, as it is known, consists in combining the practically obtained curve, constructed in the same scale, with one of the theoretically calculated curves. The disadvantage of the palette method of interpretation is the necessity of interpolation between neighboring curves on the palette. The similar nature of curves with different parameters can lead to ambiguity in the solution.
