Abstract
The results of the mineralogical and textural characterization of joint mortars and pavement samples collected at the Roman site of A Ciadella are presented. The results indicate that these are earth mortars whose most likely origin could be sub-surface horizons from nearby soils, considering the mineralogical similarity between the inherited minerals detected in the mortars and the mineralogy of the rocks in the area. No lime has been detected in any mortar. The textural analysis confirms a poor pre-treatment of the soil samples used as raw material. In the pavement samples analysed, the existence of a kaolinite-rich surface layer, probably applied deliberately on the surface, stands out.
