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
Tethys Ocean pushing the floor of the Paleo-Tethys Ocean under the eastern end of northern Pangaea (i.e.Laurasia). The Tethys Ocean formed between Cimmeria and Gondwana, directly over where the Paleo-Tethys used to be. During the Jurassic period about 150 Mya, Cimmeria finally collided with Laurasia and stalled, so the ocean floor behind it buckled under, forming the Tethyan Trench. Water levels rose, and the western Tethys shallowly covered significant portions of Europe, forming the first Tethys Sea. Around the same time, Laurasia and Gondwana began drifting apart, opening an extension of the Tethys Sea between them which today is the part of
