Spain [email protected] Received: 12-06-2014 Accepted: 12-11-2014 ABSTRACT The present work describes the study of the ceramic materials recovered in Oukaïmeden Valley, and its results. In this set of archaeological sites, we obtained information mainly from Aougnin n’ait Ourigh, and so we will examine it in detail. The site is located in one of the western platforms that access the mountain valley of Oukaïmeden. This settlement comprises a rock shelter, probably used only during the summer months. This site has provided the oldest chronologies for the presence of humans in the Moroccan High Atlas, between the late Fourth Millennium- the beginning of the Third Millennium calBC. In this shelter we recovered a small ceramic assemblage that, despite its limitations, gives us certain insight into the technological and cultural features of the Neolithic groups in an area where very little research in this particular field has been conducted so far. Other findings belonging to the Bronze Age are also examined and compared to other North African sites. KEY WORDS: Neolithic, High Atlas, impressed ware, cardial ware, grooved ware. RESUMEN Este trabajo presenta el estudio de los materiales cerámicos de cronología prehistórica conocidos hasta la fecha en el Valle de Oukaïmeden. La información procede esencialmente del abrigo de Aougnin n’ait Ourigh, que es estudiado en detalle. Este sitio se sitúa en una de las plataformas que permiten el acceso al valle desde el Oeste. Se trata de un abrigo en un gran bloque aislado de roca, ocupado con toda probabilidad solo en los meses estivales. El yacimiento ha proporcionado las fechas más antiguas conocidas hasta ahora para la ocupación humana del Alto Atlas, entre media- dos del IV e inicios del III milenio calBC, y de él procede un pequeño conjunto cerámico, cuyo análisis nos proporciona algunos datos sobre las características tecnológicas y culturales de las pequeñas comunidades neolíticas, muy poco investigadas en la región. Asimismo se estudian otros hallazgos correspondientes a la Edad del Bronce y se comparan con sus paralelos en el Norte de África. PALABRAS ClavE: Neolítico, Alto Atlas, cerámica impresa, cerámica cardial, cerámica acanalada.
