Resumo: O litoral de Vila Nova de Gaia, a sul da cidade do Porto, constitui um trecho geoarqueologico impar para o estudo da ocupacao quaternaria da fachada ocidental da Iberia. Neste trabalho apresentam-se algumas caracteristicas tecno-tipologicas das industrias liticas do litoral de Vila Nova de Gaia e avancam-se hipoteses sobre os respetivos contextos cronoestratigraficos, litoestratigragicos e geoarqueologicos. De acordo com observacoes mais ou menos pontuais realizadas durante as ultimas tres decadas sugere-se que: a) A industria litica mais antiga parece associar-se ao nivel marinho I (20-30 m a.n.m.a.m.), podendo ter sido posteriormente remobilizada na sequencia de processos coluvionares. A presenca de bifaces e de machados de mao entre os artefactos identificados remete-a para o Acheulense; b) A ocorrencia de bifaces muito boleados em depositos coluvionares que recobrem o nivel marinho II (10-20 m a.n.m.a.m.), sugere que o seu contexto primario tera sido o referido deposito marinho; c) na base do deposito do nivel marinho III da Praia da Aguda ocorrem artefactos liticos enquadraveis no Acheulense (presenca de bifaces e de machados de mao); d) nas coluvioes sobre os niveis marinhos I e II existem artefactos muito eolizados – aparentemente posteriores as formacoes marinhas e anteriores a genese das coluvioes – e artefactos sem qualquer alteracao fisica – possivelmente coevos dos processos de coluvionamento. Aspetos tecnicos e tipologicos observados nestes dois conjuntos artefactuais permitem avancar a hipotese de se relacionarem, respetivamente, com o ultimo periodo glaciar (idade minima) e com o Holocenico.

Abstract: The carved lithic artefacts from the littoral of Vila Nova de Gaia: generic characterization, geoarchaeological contextualization, problems and perspectives The coast of Vila Nova de Gaia, south of the city of Porto, constitutes a unique geoarchaeological stretch for the study of the quaternary occupation of the western facade of Iberia. This work presents some techno-typological characteristics of the lithic industries from Vila Nova de Gaia coastline and hypotheses concerning their chronostratigraphic context are presented. According to general observations carried out during the last three decades it is suggested that: a) The earliest lithic industry seems to be associated with marine level I (20-30 a.s.l.); however, it may have been subsequently remobilized by colluvial processes. The presence of handaxes and cleavers among the artefacts connect this assemblage with the Acheulean; b) The presence of rolled handaxes in colluvial deposits overlying marine level II (10-20 m a.s.l.) suggests that their primary context may have been the mentioned marine level; c) At the bottom of the marine level III deposit from Praia da Aguda (< 10 m a.s.l) there are lithics of Acheulean age (presence of handaxes and cleavers); d) In the colluvial deposits overlying marine levels I and II there are lithic artefacts with a very high degree of aeolisation – apparently younger than the marine formations and older than the colluvial processes – and artefacts with no patina – possibly synchronous of the colluvia. Technical and typological features observed in these two sets suggest that the first one may date from the last glacial period (minimum age) and the second one from the Holocene. Keywords: Lithic industries; Palaeolithic; Geomorphology; Vila Nova de Gaia.
