Evolution of the material composition of the Early Precambrian metabasites of the Kola region

The paper describes evolution of the Precambrian mafic rocks of the Kola region. This study is not possible without ranking of objects according to age of their protoliths' formation. For this purpose the method of search of trend differences of rocks groups in the specified number of sets has been developed. Its use has revealed new regularities of evolution of substance of the Kola region Precambrian complexes, manifested in the cyclical changes in the rock composition in the course of geological time.
