MICHAEL J. KENNEDY; The Fleur de Lys Supergroup: stratigraphic comparison of Moine and Dalradian equivalents in Newfoundland with the British Caledonides. Journal of the Geological Society ; 131 (3): 305–310. doi: https://doi.org/10.1144/gsjgs.131.3.0305
Whereas the NW. Fleur de Lys Supergroup shows many general similarities with the Moine and Dalradian, the SE. Fleur de Lys is dominantly volcanic and has no extensive analogues in the British Caledonides. Equivalents of these rocks may be largely covered by younger sequences on the E. side of the Atlantic.
