The analysed materials were composed by different types of earth traces: small clayish daub fragments coming from the renderings of two neolithic pits, from Defesa de Cima 2 (Évora); fragments of clayish mortars with branches prints, coming from covering and filling wood structures, from calcolithic settlement of São Pedro (Redondo, Évora); manual and perhaps
moulded mudbricks, probably belonging to a wall adjacent to a surrounding moat, from
calcolithic settlement of Alto do Outeiro (Beja); big fragments of a hut wall, probably made of stacked earth, from Alcalar calcolithic settlement (Portimão, Faro).
Earth materials were burnt by fire, which permitted their conservation until nowadays
