The Salobo Project area is inserted in the Tapirapé-Aquiri 97 National Forest (FLONATA), in the municipality of Marabá, southeast of the Pará State, where prospections for the identification of archeological sites were carried out from May to October 2003. This work aims to demonstrate the methodology used for the analysis of the ceramic material collected during the prospections with emphasis on typology. Initially the material was cleaned, then the simple and decorated fragments were separated and numbered. The analysis identified characteristics of the ceramic fragments such as: shape, antiplastic, firing type, thickness, dimensions and surface treatment of the fragments. A total of 592 ceramic fragments were quantified, being 496 bodies, 88 borders, 4 bases, 1 appliqué and 1 clay ball. Regarding the decorations of the bodies, 354 are simple (undecorated), 117 corrugated, 18 incised, 4 brushed, 3 scraped, 2 ungulate, 2 dotted, 1 rolled and 2 printed. As for the borders 56 are plain and 32 decorated - 5 ungulate, 22 incised and 5 carved. The ceramic tradition defined for the region, the predominance of crushed rock as antiplastic and of corrugated as decoration, as well as the dating (between 500 and 1600 AD) and the geographic location of the sites along the rivers, corroborate the hypothesis of Figueiredo (1977), in which the region would have been occupied by groups belonging to the Tupiguarani ceramic tradition.
