Geological and archaeological analysis of stone masonries in standing structures helps reveal information about use natural resources. At the same time, study historical materials is useful for conservators cultural heritage management. Geochemical petrographic building material types usually done through destructive on a few selected samples can be problematic due to costs operations size buildings themselves. This paper demonstrates that combination hyperspectral imaging portable Near Infrared (NIR) spectroscopy Energy Dispersive X-ray Fluorescence (ED-XRF) analysing raw used distinct construction phases inner defensive wall citadel Carcassonne (Aude, France). Stratigraphic architecture, short-range spectral remote sensing ED-XRF measurements were combined an interdisciplinary approach classify sandstone elements. The experimental protocol situ non-destructive classification masonry allows investigation monument diachronic perspective, collecting delineate varieties their or re-use time.
