2001) have shown that flexural slip was important in the tightening of folds in the Halifax Group.
At the same time the layer-slip lineation sustains a constant relationship, presumably orientated with respect to relatively fixed pinning points along the fold hinge during flexural slip (e.
This tightening and increase in curvilinearity of hinge lines indicates increasing bulk strain towards the Fredericton Fault which occurred within the same geometric framework as the initial layer-parallel flexural slip.
