Scientists have found a submerged microcontinent off the west coast of Greenland. Named the Davis Strait proto-microcontinent, it was created by tectonic activity in the region. This discovery of the New Proto Microcontinent helps us understand more about how the Earth’s crust develops.

Schematic representation of the evolution of the Labrador Sea, Baffin Bay and Davis Strait:

The formation of this microcontinent is attributed to the rifting and seafloor spreading that occurred between Greenland and North America. This process formed the Labrador Sea and Baffin Bay, linking them through the Davis Strait. A pivotal phase of east-west extension along Greenland's margin led to the detachment of this continental block.

The Davis Strait, a boundary between Canada and Greenland, has a history of tectonic activity dating back 33 to 61 million years during the Paleogene period.

The Davis Strait proto-microcontinent is a 19-24 km thick piece of thinned continental crust, surrounded by two narrow bands of thinner crust (15-17 km). These bands separate it from mainland Greenland and Baffin Island.
