Researchers have discovered a previously unknown proto-microcontinent, the Davis Strait proto microcontinent, beneath the Davis Strait between Greenland and Canada. This landmass, composed of thick continental crust, formed during the separation of Greenland and North America. The discovery highlights the significant role of lithospheric structures in influencing tectonic plate movement and suggests microcontinents are more common than previously believed.
