Baltica

From Wikipedia, the free encyclopedia
Baltica 550 mya (green)

Baltica was a late-Proterozoic, early-Palaeozoic continent that now includes the East European craton of northwestern Eurasia. Baltica was created as an entity not earlier than 1.8 billion years ago[citation needed]. Before this time, the three segments/continents that now compose the East European craton were in different places on the globe. Baltica existed on a tectonic plate called the Baltic Plate.

History

  • 1.82 billion years ago, Baltica was part of the major supercontinent Columbia.
  • 1.5 billion years ago, Baltica along with Arctica and East Antarctica were part of the minor supercontinent Nena.[1]
  • 1.07 billion years ago, Baltica was part of the major supercontinent Rodinia.
  • 750 million years ago, Baltica was part of the minor supercontinent Protolaurasia.
  • 600 million years ago, Baltica was part of the major supercontinent Pannotia.
  • Cambrian, Baltica was an independent continent.
  • Late Ordovician, Baltica collided with Avalonia (most of modern Western Europe)
  • Devonian, Baltica collided against Laurentia, forming the minor supercontinent Euramerica.
  • Permian, all major continents collided against each other to form the major supercontinent Pangaea.
  • Jurassic, Pangaea rifted into two minor supercontinents, Laurasia and Gondwana. Baltica was part of the minor supercontinent Laurasia.
  • Cretaceous, Baltica was part of the minor supercontinent Eurasia.
  • Present, Baltica is part of the forming minor supercontinent Afro-Eurasia.
