Item Acesso aberto (Open Access) Caracterização geoelétrica de área de curtume localizada no distrito industrial de Icoaraci, Bélem-Pará(2006-12) NUNES, Lana Patrícia Martins; LUIZ, José GouvêaA study covering the shallow subsurface was performed in order to investigate the possibility of underground contamination by liquids used in the industrial processing of dead animal skin to produce tanned hide. The study was carried out inside the area of the Couro do Norte industry, located in the Icoaraci Industrial District (Belém-PA). The used geophysical methodology was: resistivity (imaging and vertical electric soundings), spontaneous potential, electromagnetic (slingram) and ground penetrating radar (GPR). The integrated geophysical interpretation of data indicated the underground flow direction and a shallow plume of contamination, caused probably by the disposal of effluents by the Couro do Norte industry.Item Acesso aberto (Open Access) Metodologia geofísica aplicada ao estudo arqueológico dos sítios Bittencourt e Jambuaçu, Estado do Pará(2010-06) ARAGÃO, Rigler da Costa; LUIZ, José Gouvêa; LOPES, Paulo Roberto do CantoMagnetic, 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.
