Abstract
The heterogeneous Lewisian rocks of Coll show the effects of at least six phases of deformation. The absence of common, penetrative linear fabrics, and of representatives of the Scourie swarm of basic dykes, so useful in relative dating in most areas of Lewisian, limits rigorous analysis and regional correlation of tectonic events. To some extent the limitations have been overcome by examination of the effects of each phase on earlier structures, and of the geometry of the fold forms produced.
