Investigação com os métodos GPR e magnético de urnas funerárias do Sítio Nossa Senhora do Perpétuo Socorro (Pará)

Abstract

This paper presents the results of the application of geophysical methods in the selection of potential areas for archeological site at Nossa Senhora do Perpétuo Socorro in the state of Pará. The site has urns indigenous outcropping and sub-outcropping plenty of archaeological interest. The methods used were Magnetometry and Ground Penetrating Radar (GPR). The magnetic measurements were employed to indicate the most appropriate sites for excavation greatly reducing the potential areas. The GPR was used to confirm the anomalies detected by magnetic measurements and provide a better spatial assessment both horizontally and vertically, reducing the errors when they identify magnetic anomalies that are not caused by archaeological features. The study methodology was based on comparison of anomalies obtained from unknown areas which anomalies from areas where exists urns and roots, characterizing and grouping these anomalies.
