Abstract

In a recent short note, Lisle (2013) uses an example from the New Harbour Group of Anglesey, UK, to illustrate a type of structural lineation he terms ‘domainal trace lineation’. This is a form of intersection lineation manifested in fine banding, considered to be the intersection of one domainal foliation (e.g. crenulation cleavage) on another domainal foliation. If Lisle’s interpretation is correct, it implies that the New Harbour Group has at least four phases of deformation, compared with the two that are recognized in the underlying South Stack Group at Rhoscolyn (e.g. Shackleton 1969; Treagus et al. 2003). Furthermore, if the pervasive lineation in the New Harbour Group is considered to be an intersection lineation, this has significant consequences for the regional tectonics.
