Échaillon stone from France: a Global Heritage Stone Resource proposal
Résumé
Échaillon stone, a Mesozoic platform limestone from SE France, is proposed as a Global Heritage Stone Resource. The Échaillon stone quarries are located at the western termination of the Alps, near the city of Grenoble. Stone from the main Échaillon quarries is an Upper Jurassic to Berriasian bioclastic near-reef limestone, renowned for its two characteristic white and pink colours. Two ancillary quarries nearby, the Lignet and Rovon quarries, provided the Lower Cretaceous (Barremian to Aptian) Yellow Échaillon stone, of lagoonal origin. Échaillon stone's unique characteristics, resistance to weathering and high aesthetic values made it a prized building and ornamental material used in many significant historical buildings in Europe, North Africa and the USA. Although the first use of Échaillon stone in buildings dates from the Gallo-Roman period, the industrial use ranges from the mid-nineteenth century, during the heyday of the Beaux-Arts architecture period in France, to the mid-twentieth century. The reputation of Échaillon stone was bolstered by world-renowned architects, sculptors and artists who used it for historical building ornament and sculptures. By the turn of the twentieth century, production started to decline and it ceased by the middle of that century.
