ARCEx Postdoctoral fellow Kjetil Indrevær, at the Department of Geosciences at the University of Oslo will hold a lecture for the Norwegian Geology Association (NGF) on Thursday 22 October.

The Barents Sea has since the collapse of the Caledonian Orogeny experienced approx. 350 million years of rifting and formation of  sedimentary basins. Still, one can find small structures hidden below the sea floor that indicate that the opposite have taken place: short events of crustal shortening (called tectonic inversion).squashing-crust

How is it possible that in the midst of all this stretching, the earth’s crust suddenly was squashed?

Indrevær’s lecture will give a popular scientific introduction to 1) challenges related to seismic interpretation of inversion structures, and 2) different causes of the creation of these structures around the Barents Sea, with a special focus on the south-western Barents Sea.

The lecture will take place in the auditorium at the Department of Geology, University of Tromsø, 22 October at 16:30 (in Norwegian).
