Caledonian orogeny

Age:~505 to ~400 Ma
Geologic Time:Paleozoic
Where:Europe
The Caledonian orogeny was one of several orogenies that would eventually form the supercontinent Pangaea.

The first phase that is often included in the Caledonian orogeny is the Finnmarkian phase at 505 million years ago, followed by the Jämtlandian phase at 455 million years ago.

The main phase of the Caledonian orogeny (from about 425 to 400 million years ago) is called the Scandian phase in Scandinavia and the Grampian phase in Britain.[5] It was caused by the collision between Laurentia and Baltica.
