n. A separate continental plate that existed from the Late Precambrian to Silurian, consisting of the major part of North America, northwest Ireland, Scotland, Greenland, and pieces of Norway and Russia.
The term now used for an ancient continent. Fragments of this are preserved on either side of the North Atlantic, including Greenland, Canada and much of Scotland. The Laurentian continent collided both with Baltica (Scandinavia) and Avalonia (much of England etc) during the Caledonian orogeny.
An ancient continent that formed about 600 million years ago by the fragmentation of the super continent called Rodinia. The metamorphic rocks of Laurentia form the lower part of the crust of much of Scotland and crop out at the surface as the gneisses of the Lewisian Foreland;.
A continent in the early Paleozoic Era composed of today's North America and Greenland.
The North American craton (also known as Laurentia), like all craton land, was created as continents move about the surface of the Earth, bumping into other continents and drifting away.
