Item Acesso aberto (Open Access) Gradiometria magnética e GPR aplicados à arqueologia em sítio estuarino em Penalva - MA(Universidade Federal do Pará, 2012-11-20) ROCHA, Herson Oliveira da; SILVA, Marcos Welby Correa; http://lattes.cnpq.br/3213216758254128This research presents the results of the application of geophysical methods noninvasive, in order to indicate possible sites of deposition of materials in archaeological survey at a site located in the municipality of estuarine Penalva in the state of Maranhão. The methods used were Magnetometry and Ground Penetrating Radar (GPR). The magnetic measurements were used to indicate the locations for excavation. The GPR was used to confirm the anomalies generated by the magnetic method, providing fewer errors when the magnetic anomalies are not caused by archaeological features. Were 14 profiles performed GPR using an antenna 400 MHz and 1664 magnetic measurements using the magnetometer. During the archaeological survey conducted, based on the geophysical anomalies provided by the team led by archaeologists Deusdedit Carneiro Leite Filho and Luiz Fernando Tavares Marques made five excavations at the site, which allowed them to rescue several ceramic pieces. The results presented in this study allowed us to verify and evaluate the potential of geophysical prospecting method to assist in archaeological studies.
