“…Nevertheless, chalkstone use as building stone was quite significant in Normandy compared to other regions of the NW European Chalk Basin. In England, six chalkstones (named Totternhoe, Beer, Lavant, Chalk Freestone, Top Calcrete, Brighstone) were employed in cathedrals, abbeys, priory, castles and other constructions (Bone and Bone, 2000;Dusar et al, 2011;Lott, 2011;Bone, 2016), while the French cathedrals of Amiens, Beauvais, St-Omer and Troyes were edified in chalk (e.g., Lafrance et al, 2016). In the meantime, Avendersteen and Lézennes from Hainault and Flanders counties in northern France was also exported to Belgium and Holland mainly for sculpturing (Tolboom et al, 2009(Tolboom et al, , 2010 and Vylen chalkstone for vernacular use was quarried in the Belgian/Dutch border area near Maastricht (Dreesen and Dusar, 2004;Dusar et al, 2009;De Kock et al, 2015).…”
