The Baltic Shield is defined as the "exposed" Precambrian northwest segment of the East European Craton.
The Baltic Shield is divided into five provinces: the Svecofennian and Sveconorwegian (or Southwestern gneiss) provinces in Fennoscandia, and the Karelian, Belmorian and Kola provinces/cratons in Russia.
There is considerable misunderstanding in the literature with the use of the term "Baltic Shield." A shield in any craton is the area of exposed crystalline crust while the other part of a craton is a “platform” where the crystalline crust or basement is overlaid by younger sedimentary cover.

 Shield
In heraldry, the shield is the principal portion of a heraldic achievement or coat of arms.
A shield volcano is a volcano that, because of its domical shape, resembles a warrior's shield.
Shield volcanoes are formed by lava of low viscosity that flows easily; consequently, the volcanic dome is built up over time by flow after flow of fluid basaltic lava that issues from vents or fissures on the surface of the volcano.

Russia is ready to cooperate with the Baltic countries with a view to actively countering risks and threats that may arise in the 21st century and strengthening stability through reliable trust and partnership.
We need transparency of intentions in our bilateral relations with the Baltic states, clarity of one another's plans, and prevention of any kinds of activities that may be regarded by Russia or its neighbors as a potential threat.
The peculiarity of the future risks is that they cannot be removed with the help of military instruments: hence the growing role of peacemaking efforts, preventive diplomacy, especially when the matter at issue is ethnic conflicts, and new and efficient forms of interaction in combating crime.

Precambrian rocks often occur in shields, which are large areas of relatively low elevation that form parts of continental masses.
One of the largest exposed areas of Early Precambrian rocks is the Canadian Shield, where geologist Sir William Logan did his pioneer work.
Among the other shield areas composed of Early Precambrian rocks are the Angara Shield in Siberia, the Australian Shield, the Baltic Shield in Europe, the Antarctic Shield, and the African Shield comprising most of the African continent.

Tectonic models explaining the earliest Palaeoproterozoic evolution of the Kola region, north-eastern Baltic Shield, are usually identified as (i) extensional or (ii) combination of extension and compression zones.
In the northern Baltic Shield extensive reworking of the Archean basement occurred between 2.45 and 1.8 Ga. The earliest episodes of reworking were associated with rifting and formation of volcanic-sedimentary basins, whereas, the later stages related to accretion of juvenile Svecofennian terranes in the south and collisional orogeny in the north in the Lapland-Kola belt.
In that region, the Svecofennian Domain of the Baltic Shield and its continuation in the basement of Estonia, Latvia and western Lithuania were formed between 1.9 and 1.8 Ga by the accretion of several magmatic arcs and intervening depositional basins (e.g.

The largest area of oldest rocks is the Baltic Shield, which has been eroded down to a low relief; the youngest rocks occur in the Alpine system, which still survives as high mountains.
The first is in shields, like the Baltic Shield, which are large areas of stable Precambrian rocks usually surrounded by later orogenic belts.
For example, the sediments of the Russian Platform are underlain by Precambrian basement, which extends from the Baltic Shield to the Ural Mountains, and Precambrian rocks underlie the Phanerozoic sediments in southeastern England.

First, it is necessary to understand the structural nature of basement, and here I refer to Precambrian metamorphic basement that comprises the major shield areas of the world, such as the Canadian Shield, South American Shield, African Shield, Baltic Shield, etc.
Shields are simply the outcropping areas of cratons, or continents, and similar metamorphic terranes are located under all cratonic sedimentary basins.
Figure 1 is a Landsat photograph that covers a portion of the Canadian Shield (NW part) and a portion of the adjacent Ontario sedimentary basin (SE part), where the shield is overlapped by oil-bearing lower Paleozoic strata.
