Named after the Avalon Peninsula, Newfoundland, a small early
Palaeozotic crustal plate consisting of parts of the maritime
states of North America, England, Wales, South-East Ireland and
Western Europe, which split from Gondwana early in
the Ordovician, moved Northwards and finally collided first with
Baltica in the late Ordovician and with
Laurentia during mid-Siluration times following
closure of the Iapetus Ocean.
