Parts of Gondwana found off Australia
SYDNEY, Nov 17: Australian scientists exploring areas of the Indian Ocean said on Thursday they had found sunken parts of the megacontinent Gondwana which could offer clues on how the current world was formed.
The two “islands” were found on the remote sea floor in international waters 1,600 kilometres west of Australia during a surveying trip last month.
Their rocks contained fossils of creatures found in shallow waters, meaning they were once part of the continent at or above sea level rather than created by undersea volcanic activity, said Sydney University geophysicist Jo Whittaker.
She called it an exciting discovery which would hopefully shed light on how Gondwana broke into present-day Australia, Antarctica and India between 80 and 130 million years ago.
Whittaker, one of the key researchers, said she was particularly interested in exploring India’s drift first northwest and then sharply north, where its northeast coast, once joined to Australia, smashed into Eurasia, forming the Himalayas.
“We have a fairly good idea where those continents were but we don’t exactly know, the eastern Indian Ocean is one of the more poorly explored parts of the world’s oceans in terms of tectonics,” she said.—AFP
