Palaeozoic and Early Mesozoic rotation and drifting of Shan-Thai from Gondwana-Australia; C. Gondwana formed prior to Pangaea, then became part of Pangaea, and finally broke up. It is prevalent in Eurasia and the Americas as well as in the Austronesian speaking areas of S. North America had just begun pulling away from Eurasia during the Jurassic, and South America had started to split off from Africa, from which India, Australia, and Antarctica were also. Early in geologic times, a supercontinent called Pangea, sometimes known as Pangaea, included almost all of the planet’s landmasses. In Eurasia, radiations between the Oligocene and Early Miocene resulted in the segregation of the clades of North African origin c. Within Gondwana, from the Late Jurassic to the Mid-Cretaceous, Africa and South America formed a land mass called West Gondwana (e. Previous studies concluded that a Trans-Tethyan oceanic subduction zone existed prior to Paleogene India-Eurasia collision, when the ocean lacked intervening continental slivers.

Some of these are fragments of Gondwana or other ancient cratonic continents: Zealandia,. In paleogeography, Gondwana also Gondwanaland, is the name given to the more southerly of two supercontinents (the other being Laurasia) that were part of the Pangaea supercontinent that existed from approximately 510 to 180 million years ago (Mya). il)A) Tectonic fragmentation of the supercontinent Gondwana through time, showing Africa's drift northwards; and (B) main climatic events in Africa during Neogene (adapted from Senut et al. As pieces were added to Gondwana on its South-American, Antarctica and Australia side, ribbon-like micro-continents were detached from its African and South. Furthermore, we suggest that (1) rifting of the Pontides-Transcaucasus block (PTB) from Gondwana at 450–350 Ma could have been driven by roll-back of the south-dipping Rheic slab, (2) that the main metamorphic and coeval magmatic events are related to the accretion of the PTB to the Eurasian margin at c.
