Temagami Greenstone Belt was south of Laurenta, Siberia was just south of the equator east of Laurenta, and Gondwana lied mostly in the Southern Hemisphere. Subsequently, Baltica, Laurenta and microcontinent Avalonia collided in the Devonian period (416-359 million years ago) to form minor supercontinent Euramerica. This eventually started to collide with Gondwana and other landmasses to form supercontinent Pangaea 255 million years ago. In the Late Triassic period some 152 million years ago, Pangaea split into two minor supercontinents, namely Gondwana and Laurasia. The TGB represented a minor portion of western Laurasia until it divided into Eurasia and North America about 94 million
Geology of Saskatchewan and marine life. The Williston basin was formed creating a lowered land area during this period filling with the Winnipeg Sea. The Williston basin was mainly south of Saskatchewan but extended north into the Saskatchewan plains area. Laurasia was created near the end of the Silurian Period. Laurasia was formed from the joining of Laurentia with Gondwana and two smaller continents which had broken off Rodinia. The orogeny between Laurasia and Gondwana created the Appalachian Mountains, and an exodus of water from the Laurasian land surface. In the early Devonian Period 418-361 Ma, Laurasia separated from Gondwana, creating a depressions
