Geochemical criteria for the potential ore content of igneous and metamorphic rocks

For more than a hundred years, discussions have been held about the possibility of extracting genetic information from empirical distribution curves of various components in rocks. Also, the relevance of the question is determined by the requirement to develop new techniques to increase the volume of geological and genetic information extracted from the growing flow of analytical data. The successful solution of a number of topical problems of geology, first of all, the possibility of restoring the geochemical orientation of petrogenic and ore-bearing processes, and assessing the potential ore content of crystalline rocks, is closely linked with the physical and mathematical justification of the distribution laws. Based on this, the article discusses the methodology for assessing the potential ore content of igneous and metamorphic rocks, which is based on the results of mathematical modeling of the geochemical dynamics of petrogenic processes. Earlier, the authors proved that when obtaining regular distribution curves of certain chemical elements, a modal value can be given a certain thermodynamic meaning. Empirical distributions can be considered as a characteristic of the probabilistic state of systems, and modal values in them — as the most probable (optimal state) to which systems aspire. Some features of analytical studies that are required for the use of mathematical modeling and subsequent reliable interpretation of the results are indicated.

Keywords: geochemistry, igneous rocks, metamorphic rocks, ore bearing, mathematical modeling, distribution curves, bimodal distribution, empirical distribution curve.
