The North Armorican composite terrane, NW France, is a collage of displaced terranes which result from the amalgamation of Cadomian continental arcs and marginal basin complexes by sinistral transpression along a continental margin above a subduction zone.

Cadomian events thus span a considerably greater period than previously supposed.
