The Baltic Shield (or Fennoscandian Shield) is a segment of the Earth's crust belonging to the East European Craton, representing a large part of Fennoscandia, northwestern Russia and the northern Baltic Sea. It is composed mostly of Archean and Proterozoic gneisses and greenstone which have undergone numerous deformations through tectonic ...
The Scandinavian Peninsula occupies part of the Baltic Shield, a stable and large crust segment formed of very old, crystalline metamorphic rocks. Most of the soil covering this substrate was scraped by glaciers during the Ice Ages of antiquity, especially in northern Scandinavia, where the Baltic Shield is closest to the surface of the land.
The Transscandinavian Igneous Belt (Swedish: Transskandinaviska magmatiska bältet), abbreviated TIB, is one of the major lithological units of the Baltic Shield.It consists of a series of batholiths in Sweden and Norway forming a ca. 1400 km long belt running from Lofoten, Norway, in the north to Blekinge, Sweden, in the south.
Baltic Shield, part of the East European Craton; Fennoscandian Shield, the exposed Northwestern part of the Baltic Shield in Norway, Sweden and Finland (3.1 Ga) Karelian Craton, part of the Fennoscandian Shield in Southeast Finland and Karelia Russia, (3.4 Ga) Kola Craton, part of the Fennoscandian Shield, Kola Peninsula, Northwest Russia
A shield in any craton is the area of exposed crystalline crust while the other part of the craton is the “platform” where the crystalline crust or basement is overlaid by younger sedimentary cover. Thus the crustal segments of the East European Craton comprise both the Baltic Shield and the Ukrainian Shield, and the sedimentary platform ...
The similar term Fenno-Scandinavia is sometimes used for Fennoscandia. Both terms are sometimes used in English to refer to a cultural or political grouping of Finland with Sweden, Norway and Denmark (the latter country is closely connected culturally and politically, but is not part of the Fennoscandian Peninsula), which is a subset of the ...
Geological map of the Scandinavian Peninsula and Fennoscandia: the Svecofennian orogen is shown in yellow. The blue areas to the west are the Transscandinavian Igneous Belt. The nappes emplaced by the much younger Caledonian orogeny are shown in light green.
The geology of Denmark includes 12 kilometers of unmetamorphosed sediments lying atop the Precambrian Fennoscandian Shield, the Norwegian-Scottish Caledonides and buried North German-Polish Caledonides. The stable Fennoscandian Shield formed from 1.45 billion years ago to 850 million years ago in the Proterozoic. The Fennoscandian Border Zone ...
