Ceramic technology and resource use during the early neolithic in Central-Southern Portugal

Petrographic analysis of 49 sediments and 63 Neolithic ceramics from eight sites of Estremadura and six sites of the Algarve of central and southern Portugal, respectively, discerned distinct production technologies for each area. Raw materials available near archaeological sites were utilized. Fabrics that do not correspond to regionally available materials, however, indicate imports or migration. This suggests the existence of bidirectional maritime routes rather than south-north only, as predicted in current models of the neolithization of coastal Portugal. Seven ceramics and seven sediments were selected for elemental analysis. The results supported the patterns in the petrographic analysis
