This meeting marked the fiftieth anniversary of Tuzo Wilson’s landmark paper asking “Did the Atlantic close and then re-open?”.

This paper was one of a series of papers he published which led to the “Wilson Cycle” concept in which the repeated opening and closing of ocean basins along old orogenic belts is a key process in the assembly and breakup of supercontinents. This implied that the processes of rifting and mountain building somehow pre-conditioned and weakened the lithosphere in these regions making them susceptible to strain localization during future deformation episodes.

It is now generally accepted that most geological architectures are controlled by interactions between plate motions, the horizontal mechanics of the lithosphere and pre-existing structures in the crust. However, our detailed understanding of the processes of structural inheritance is still very limited. This 3-day meeting brought together geophysicists, structural geologists, and modellers in order to re-assess the legacy of the Wilson Cycle concept and how our understanding inheritance in continental tectonics has evolved over the past 50 years.

Field Trip

There was a four-day, post-conference field excursion to the Scottish NW Highlands to observe and discuss basement inheritance and reactivation processes in the field. This took place from Thursday, 26 to Sunday, 29 May 2016. 

Special Publication

A Geological Society special publication is planned containing papers linked to presentations at the meeting.
