Researchers have found a brand new microcontinent between Greenland and Canada.
Davis Strait, positioned between Canada and Greenland, has been discovered to host a beforehand unknown protomicrocontinent – a piece of crust that has not utterly separated from the continent and is beneath water in sea water.
This protomicrocontinent has unusually thick crust, reaching 19-24 kilometers, far exceeding the conventional thickness of oceanic crust. The examine, printed within the journal Gondwana Analysis, led by PhD college students Luke Longley and Dr Jordan Fetean from the College of Derby and Dr Christian Schiffer from Uppsala College, seems on the tectonic historical past of this area over the 30 million years in the past.
Scientists used gravity and seismic reflection knowledge to reconstruct the plate actions that created this microcontinent. Their analysis reveals that the ascent between Canada and Greenland started about 118 million years in the past, and that the ocean ground started to unfold within the Labrador Sea and Baffin Bay about 61 million years in the past. again About 49-58 million years in the past, there was a change within the route of seafloor spreading that contributed to the formation of the Davis Strait microcontinent.
Dr. Fetean famous the significance of this discovery: “The examine of the formation of microcontinents helps to realize a greater understanding of the Earth’s tectonic processes, which is necessary for predicting future tectonic modifications and for establish new pure sources.” The examine can also be related to different microcontinents, equivalent to Jan Mayen, northeast Iceland, and the East Tasman Rise, off the coast of Tasmania. A greater understanding of those processes has the potential to mitigate tectonic hazards and mineral exploration.
Subsequently, the invention of a protomicrocontinent between Greenland and Canada not solely expands our data of plate tectonics, but additionally opens up new alternatives for additional analysis and sensible software.
