The purpose of this study was to estimate and compare seismic properties of soil under different geological conditions of the southern part of the Baltic Shield and the northwestern part of the East European Platform.
Historical mining for iron ore, copper, zinc, lead and silver within the more accessible parts of Norway, Sweden and Finland proved that the potential of the Baltic Shield rocks hosting economic deposits was no less than that of shield areas in other parts of the world.
A sampling of topics includes: Palaeoproterozoic supercontinents and global evolution, the Columbia connection in North China, and timing and duration of Palaeoproterozoic events producing ore-bearing layered in intrusions of the Baltic Shield. The book is intended to be used as a reference by students and geoscientists.

These results indicate that the timing and spatial relationships of the magmatic activity at ca 1630-1600 Ma in the crystalline basement of NW Lithuania correlate well with magmatic events in the Baltic States and the Baltic Shield in Sweden, suggesting a number of episodic pulses of magmatism and a prolonged temporal evolution of the Riga batholith.

Geologically the area is of interest because the Karelian basement is part of the ArchaeanProterozoic Baltic Shield, which includes large parts of Finland and northwest Russia.
Their correlation with coeval deformation zones of the Baltic Shield in Sweden, also in Belarus, Latvia and Poland, can help to reveal the regional structure of the East European Craton around the Baltic Sea.
The regional granulite metamorphism, coupled with high rock density and magnetization, conceals the geological and potential field patterns characteristic of the proper Svecofennian in the Baltic Shield and North Estonia.
The North-Onega area lies in the northern region of the East European platform, near the Baltic Shield. The area contains four deposits: Iksinskoye, Plesetskoye, Densilavskoye, and Treugolnoye, all in the hollows and valleys of pre-Carboniferous relief, near the contact of basic volcanogenic and crystalline rocks of the Vetronny Poyas with Paleozoic sedimentary rocks.
In this study we compared the relationship between heavy mineral assemblages typical of the Baltic Shield (apatite, amphiboles, pyroxenes, zircon, garnet, epidote, tourmaline, staurolite, sphene, corundum, sillimanite, monazite, magnetite, and ilmenite) and the local bedrock (hematite, leucoxene, pyrite, micas, limonite, phosphates, carbonates, anatase, barite, and chlorite) (Jouzapavicius 1976; Viiding 1976).
