In the city of Santons, since the Roman conquest, buildings have been erected on a sedimentary basin offering to the builders a range of limestone stones recognized for their quality. The research extended to the whole territory consists in making the link between quarries and buildings. To do this, the main quarries were chemically identified in the form of repositories from which the architectural blocks brought to light by the excavations could be compared in order to know their provenance. Scanning electron microscopy (SEM), equipped with an EDS (energy dispersive spectroscopy) analyzer for the multi-elemental chemical analysis of grains trapped by marine sedimentation, is the main tool for this identification. This technique makes it possible to understand the circuits of production and trade of the stone. This article has as goal to review and assess fifteen years of research and analysis in this subject.
