Geochemical characterization of “Lorraine limestones” from the SaintPaul Cathedral of Liège (Belgium): assumptions for the true provenance of the building stones

peer reviewed ; We investigate the provenance of the ochre building stones called “Lorraine limestones” used for architectural specifc elements of the Saint-Paul Cathedral in Liège (Belgium) between the thirteenth and ffteenth century. A multi-analytical approach, including archives study, petrography and Rare Earth Elements geochemistry, has been performed to characterize the stones used in the church and to compare them with ochre limestones outcropping in the north-east of the Paris Basin. Our study suggests that a very restricted geographical area near the ancient port of Donchery (Ardenne... Mehr ...
