文摘
- •
Conjugate mid-Norwegian – East Greenland crustal-scale transects reveal a significantly narrower (pre break-up) stretched zone on the southern (Møre) transect.
- •
Post-Caledonian detachments can be traced from onshore Norway to the Continent-Ocean-Boundary.
- •
The asymmetry in extensional style observed across the Jan Mayen Lineament (JML) can be explained by different dip in the subducting Baltica Plate.
- •
The Lower Crustal Body (LCB) Type I is about 60% thicker on the Greenland side, for both transects.
