Geologists just Revealed that Between England and France Exists an Ancient Connection

According to new research, not two, but three really old continental land masses collided to give birth to the British mainland. For centuries, scientists believed that Scotland, Wales and England were created as a result of the Avalonia and Laurentia merger which would have occurred more than 400 million years ago.

However, new data led geologists from the University of Plymouth to bring in a new theory. Apparently, they now believe that a third land mass was involved into this process, Armorica. Published in Nature Communications, the findings followed a prolonged study of the mineral properties analyzed from exposed rock features found across Cornwall and Devon.

They have revealed that a clear boundary can be made running across the two counties. The northern areas apparently share the geological roots with the rest of Wales and England, while everything south is linked geologically to mainland Europe and particularly, France. These findings allowed scientists to reach certain conclusions.

For example, this explains why there is an abundance of tungsten and tin in the far South West of England. These metals are found all across Brittany and mainland Europe but they aren’t so numerous in the rest of the United Kingdom.

Dr. Arjan Dijkstra, the research’s lead author, said that “This is a completely new way of thinking about how Britain was formed. It has always been presumed that the border of Avalonia and Armorica was beneath what would seem to be the natural boundary of the English Channel. But our findings suggest that although there is no physical line on the surface, there is a clear geological boundary which separates Cornwall and south Devon from the rest of the UK”.

Approximately 22 sites were visited for this research, all of them in Cornwall and Devon, which were left exposed after various geological events, such as volcanic eruptions in the underground.
