In The Geology of Game of Thrones, a group of geologists has created a geologic map of Westeros and Essos, as well as an invented geologic history of the planet on which George R. R. Martin’s epic takes place.

Fans of the HBO TV show, currently in its fourth season, are familiar with the Game of Thrones landscape from the show’s opening credits. And, like a lot of fantasy stories, the Game of Thrones books contain maps of the imaginary world. So putting together a map was a matter of doing a little detective work and applying some core principles of geology (albeit in the most rigorous way possible) (via blogs.agu.org)

You can read the entire geological history of Westeros at Generation Anthropocene and also listen to the Generation Anthropocene podcast interview with the map creator Miles Traer.
