REGIONAL METAMORPHISM AND STRATIGRAPHY OF THE BASEMENT OF THE UKRAINIAN SHIELD
Geological Journal, 2023 Stratigraphic complexes of the Lower Precambrian are everywhere metamorphosed. Therefore, the stratigraphic subdivision of the Lower Precambrian has always been inextricably linked with the study of metamorphism. For some time, the degree of metamorphism of the complexes was even used as an indication of their relative age.
