Metodologia geofísica aplicada ao estudo arqueológico dos sítios Bittencourt e Jambuaçu, Estado do Pará

Abstract

Magnetic, total count gamma radiation, and Ground Penetrating Radar (GPR) measurements were carried out on two archaeological sites located adjacent to the place where a miner duct will be buried. The aim of the measurements was to indicate the optimal áreas for archaeological excavation to find subsurface remains related to ancient communities that lived in the sites. Magnetic measurements showed anomalies that lead to the discovery of a large amount of ceramic fragments and other remains. Gamma radiation allowed discriminating argillaceous from sandy soil, an important result since sandy soil can be correlated to the archaeological layer, where remains are normally found. Ground penetrating radar confirmed the magnetic anomalies and showed several other anomalous features not related to the archaeological remains.
