Abstract
The article deals with current “Сorrelation chronostratigraphic scheme of еarly Precambrian formations of the Ukrainian Shield” should be divided into two parts: the “Correlation stratigraphic scheme of the Lower-Precambrian formations” and “The scheme by age dividing of non-stratified Lower-Precambrian formations”. They have to be separately approved by two relevant subsections of the Lower Precambrian section NSC of Ukraine. Also, the role of intrusive and ultrametamorphic formations in determining of the stratum position in the stratigraphic scheme should be taken into account.
