When all the continents collided about 290 million years ago, they formed the supercontinent Pangaea. After millions of years this supercontinent began to pull apart once again, creating new land masses. The land mass that we call Nova Scotia was originally part of the offshore marine environment and coastal areas of two different ancient continents, Gondwana (in the south) and Laurasia (in the north.) The place where these two land masses came together is called the Cobequid-Chedabucto Fault Zone. This largely invisible fault line splits mainland Nova Scotia into the Avalon Terrane to the northeast and the Meguma Terrane to the southwest. Most of Nova Scotia’s gold bearing lodes are located in the Meguma Terrane.

A Terrane is a region that is geologically distinct from its surroundings; it was originally associated with one tectonic plate but, because of continental movement over the course of millions of years, it has become attached to another plate with a different geological history. The rest of the land once associated with the Meguma Terrane may now be located along the western edge of Spain and Portugal or along the northwestern coast of Africa.
