Researchers at the UK's University of Derby found the Davis Strait proto-microcontinent beneath the Arctic Ocean while studying plate tectonics. The landmass was created through rifting between Greenland and North America.
The team used crustal thickness data from gravity maps, seismic reflection data, and plate tectonic modeling to identify the newly found microcontinent. Their focus was on understanding the formation of the 11-14 miles thick proto-microcontinent.
'The aim of our work is to understand their formation well enough to predict that very future evolution.' - Dr Jordan Phethean. They pointed out that microcontinent formations are ongoing phenomena.
Scientists tracked seafloor movements over millions of years using mapping techniques, revealing the ancient separation of the thick continental crust from Greenland.
