Abstract
Some problems of dating the most important stratigraphic units of the Early Proterozoic Pechenga Structure are considered. The structure is composed of rocks of the Pechenga Complex, which in turn is divided into well-studied formations of the North-Pechenga subcomplex and poorly studied formations – the South-Pechenga subcomplex. This structure is one of the most studied Early Precambrian structures in the world. Volcanites of the Pechenga Structure have been studied for nearly half a century. However, many determinations of the isotopic ages of reference levels of geological crossection were carried out by insufficiently accurate Rb-Sr, Sm-Nd, and other methods. Nevertheless, in recent years, using the modern U-Pb method, age characteristics of the most important stratigraphic units of the North-Pechenga subcomplex have been obtained.
