The dyke swarm has been considered to be a result of a failed rift in the Bothnian Sea that developed as part of an extensional tectonic setting within the supercontinent of Columbia. At various location dykes of the swarm cut across Jotnian sediments indicating a Postjotnian age for the dyke swarm. Viewed in a map the dyke swarm has the form of a 90-degrees fan radiating open to the east from a point in the Bothnian Sea.[1]

gollark: That's not well-defined.

gollark: LAN: you have a link local address, which is specific to an interface and only routed on the LAN, and are automatically assigned a global one mostly.
gollark: Although some have NAT.
