X-ray diffraction and petrographic analyses of soils, clays and tempers collected around the archaeological site of Kuntur Wasi, near San Pablo, in the northern Peruvian Andes, aim at investigating the composition of local materials and the possibility of on-site production. The results of the XRD study shows that the analyzed clay found around the site is an illite, while the other collected soils from San Pablo are not clays of ceramic production range. The volcanic temper used by modern potters eight kilometers north of the archaeological site is very similar to the temper observed in many of the ancient ceramics from Kuntur Wasi. Also, analysis of clays from the middle Jequetepeque valley shows the presence of kaolin, which is absent from the analyzed clays in the Kuntur Wasi region.

This article presents the petrographic study of 21 thin sections of ceramics from the Formative site of Puémape, on the northern litoral of Peru, a site with strong afiliation to the Cupisnique culture. The results suggest the existence of several local productions, with a difference in resource area and manufacture between the Middle and Late Puemape phases. A graphite-on-red decorated bottle stands out as non local, for its intrusive composition and unique stylistic character. Its occurence is examined in view of other ceramics of similar type and composition found in the Jequetepeque valley.

This paper introduces the first results of the archaeological research carried out at the Sector José Olaya – Sitio Iglesia Colonial de Huanchaco. The excavations yielded occupations associated with the Late Initial Period and the Early Horizon. The paper describes the occupations, burials, shellfish, and ceramic identified. The latter is also studied through petrographic analysis done on selected samples. Finally, a stratigraphic study plus the aid of 11 AMS dates, allowed to build a local chronology divided into three subphases: José Olaya 1 (1000-800 B.C.), José Olaya 2 (800-600 B.C.) y José Olaya 3 (600-400 B.C.).

En este artículo se presentan los primeros resultados de las investigaciones realizadas en el Sector José Olaya – Sitio Iglesia Colonial de Huanchaco, donde se ha registrado una ocupación del periodo Inicial Tardío y el Horizonte Temprano. En este artículo presentamos los datos de los contextos arqueológicos excavados, así como un análisis preliminar de la cerámica asociada, estudio de los restos malacológicos y algunos datos del análisis petrográfico. Al mismo tiempo, un análisis de la estratigrafía del sitio y 11 fechados AMS, ayudan a separar estas ocupaciones en tres subfases: José Olaya 1 (1000-800 a.C.), José Olaya 2 (800-600 a.C.) y José Olaya 3 (600-400 a.C.).
