Abstract
This basement area corresponds to the western margin of the Iapetus Ocean which extended from Scandinavia to the southern U.S.A. (and probably still further South) during Lower Palaezoic times. It is made up of two different types of terrain; in the North, pre-Grenvillian terrains dated at between 1,370 and 2,480 Ma and, in the South, Grenvillian terrains yielding ages around 955 Ma. An ancient suture zone can be defined between these two types of terrains — this is known as the Grenvillian Suture.
