Abstract: 

The interest in Svidnya potassic-alkaline magmatic association is determined by the specific mineral and chemical composition of the rocks, their genesis and geodynamic position as well as by the possibilities to use some of them as a complex mineral raw material. The present study is focused on the differentiation tendencies of the four phases, which produced the rocks of Svidnya association. This allows drawing some conclusions about the entire differentiation process.
