East European Craton
The European part of Russia lies on the East European platform, a region up to 3,000 kilometres (1,900 mi) wide covered by more than 3 kilometres (1.9 mi) of metamorphosed sediments dating back to the Riphean stage (middle to late Proterozoic, from 1,400 to 800 million years ago). These sediments lie on the East European craton, a remnant of Precambrian continental crust composed of magmatic and metamorphic rocks. The East European craton itself was created between 2.0 and 1.7 billion years ago when the microcontinents of Fennoscandia, Sarmatia and Volgo-Uralia collided.

Famous quotes containing the words east and/or european:
“We have heard all of our lives how, after the Civil War was over, the South went back to straighten itself out and make a living again. It was for many years a voiceless part of the government. The balance of power moved away from it—to the north and the east. The problems of the north and the east became the big problem of the country and nobody paid much attention to the economic unbalance the South had left as its only choice.”
—Lyndon Baines Johnson (1908–1973)
“The Indian is one of Nature’s gentlemen—he never says or does a rude or vulgar thing. The vicious, uneducated barbarians, who form the surplus of overpopulous European countries, are far behind the wild man in delicacy of feeling or natural courtesy.”
—Susanna Moodie (1803–1885)
