About one important petrochemical regularity

Abstract

By "petrochemistry" we should understand the totality of our information about the chemical composition of rocks, consisting of “many” (in the mathematical sense) chemical analyzes of rocks, and the conclusions that can be drawn from this information. Developing those methods of calculation of chemical analysis that were used by Michel-Levy and Ozanne, the author of this article has shown in other works that the main features of the chemical composition of igneous rock, data in its analysis, can be especially conveniently reflected in the form of such series of ratios, the sum sets of which uniquely reflects the set of chemical analyzes and is equivalent to it (see article). The diagram clearly shows the desired correlation between the lengths and directions of the strokes, depending, obviously, on their position on the diagram. This shows an important correlation between the characteristics of the salic and femic components of an igneous rock.
