Sítio arqueológico do Pororó: um cerrito na mesoregião centro ocidental riograndense (Pinhal Grande)

Abstract

This paper presents the Archaeological Site of Pororó, located on the property of Mr. Lucas Somavilla (Pinhal Grande-RS), and researched through the Project for the Valorisation of Archaeological Heritage of the Fourth Colony of Italian Immigration - RS" of the Federal University of Santa Maria, under the coordination of Professor Saul Eduardo Seiguer Milder. Through the interventions was possible to realize that this site is composed of a Cerrito, demonstrating its similarities with other existing sites in Prata, and a prominent position in area and altitude (518 m), unusual for these structures. This site has only lithic materials - 10026 units - of which 52.9% are taken as constructive materials of this structure (basalt and rhyolite) and the rest as tools and refuse (basalt, rhyolite, silicified sandstone, chert, chalcedony, hyaline quartz and quartzite). The materials were analyzed with emphasis on their production methods and lithological genesis, thereby instruments were identified from the façonnage e dèbitage, and sources of local raw materials that would not exceed 7 km distance to the Cerrito. The Archaeological Site of Pororó has calibrated C14 dates between 2341 B.P. and 2692 B.P., and another obtained by OSL of 4540 ± 390 B.P.. This paper is divided into three chapters, which have consecutively: the phenomenon of Cerrito do Prata and associated ethnohistorical groups; the Archaeological Site of Pororó and its location in the landscape; and analysis of material culture obtained in field interventions.
