Results of the intervention carried out in the Special Protection Area of the prehistoric settlement of Leceia (Oeiras). Contribution to the knowledge of the geomorphological evolution of the surrounding archaeological space

Abstract

The result of the archaeological surveys conducted on the slope underlying the platform where the prehistoric settlement of Leceia (Oeiras) was implanted are presented. The collected elements point to a remarkable geomorphological evolution of that area after the abandonment of the settlement, due to anthropic causes, the primitive surface of the soil being located during the Early Chalcolithic (2800/ 2500 BC) in the lower part of the slope investigated, about 2.5 m to 3.0 m below the current topographic surface of the slope.
