India was part of Antarctica billion years ago says geologists, they have also found evidence supporting the hypothesis.
It is said that the continents were separated and reunited several times due to tectonic movement of plates before the evolution of mankind.
A group of geologists from India and Switzerland researching on the evolution of the Earth’s crust studied ancient rocks of the continental crust in the Eastern Ghats area and found important clues to the formation of the continents.
“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 PTI.
India was part of Antarctica before it got separated by an ocean, the crust broke apart separating India from Antartica and now there is a big ocean between the two land masses.
Two land masses have actually combined several times in the earth history says the research report.
India was part of Antarctica much before the evolution of mankind on earth and the research team collected evidence at the junction of the Singhbhum Craton and the Eastern Ghats in Odisha and Jharkhand.
Junction of Singhbhum Craton and the Eastern Ghats holds important clues to the formation and evolution of the continents and mountains, especially in the context of the tectonic and geodynamic evolution of the Earth.
The continent has been moving because of the plate tectonic process and which also explains why there has been mountain forming process.
The coming together of landmasses is usually triggered by large-scales tectonic processes such as melting of the mantle or voluminous volcanic eruptions.
This all activity can also have a significant change in the climate process and can also affect the atmosphere.
