R. Foulger, Dieter Franke, Laurent Geoffroy, Laurent Gernigon, Bob Holdsworth, Ken McCaffrey, Alex Peace, Kenni Petersen, Randell Stephenson, Kim Welford (and others?)
North Atlantic workshop 11/2017, Durham

2. Outline Introduction (Tony & Christian)
Definition and scales of inheritance/reactivation/reworking from lithospheric to grain scale (Bob)
Overall North Atlantic structure (Erik)
North Atlantic inheritance at different scales (observations and models/concepts)
Wilson Cycle and modifications/extensions (Christian)
Lithospheric scale reactivation
Basin scale
Sub-basin to grain scale
Discussion (under construction)
The Wilson Cycle revisited
How important is reactivation for the NA.
Where does it and where does it not work (map)
What are the geological/geodynamic prerequisites
Wider applications (is the NA typical for continental breakup? Can it be used as a template)
Future directions (Imber paper)
