Geologists have found evidence supporting the hypothesis that Indian subcontinent was part of Antarctica a billion years ago but were separated and re-united several times due to tectonic movement of plates before the evolution of mankind.

“It is for the first time that we have been able to prove the hypothesis that the continent of Antarctica and subcontinent India were once a single large continent that broke apart about 1.5 billion years ago,” IIT Kharagpur geologist Dewashish Upadhyay, who led the research told.

India and Antarctica then got separated by an ocean.

 

“This ocean closed again with the movement of the landmasses and the two continents approached each other until they collided again around one billion years ago to form the Eastern Ghats mountain belt,” he said.

 

All this happened much before the evolution of mankind on earth and the research team collected evidences at the junction of the Singhbhum Craton and Eastern Ghats in Odisha and Jharkhand.

Mr Upadhyay and his team found some of the oldest remaining vestiges of the early earth’s crust in the region and then using the minerals in the rock they worked out the sequence of geological events and date the events using radioactive isotopes.

“This research has revealed this interesting dance of the continents and probably constitutes the best examples we currently have of this phenomenon, where ocean-opening and ocean-closing happened several times,” Mr Mezger said.
