Aplicação de métodos geofísicos em Arqueologia: desenvolvimento de metodologias eficazes de prospecção geofísica aplicadas a diferentes ambientes arqueológicos

Abstract

The use of geophysical methods applied to Archaeology, in the exploration of buried structures in the sub-surface, is an imperative need in the previous steps to excavations or archaeological surveys, playing an important role in the delimitation of archaeological sites, making it more effective protective actions archaeological heritage. With regard to planning an archaeological exploration, geophysical methods significantly reduce the runtime and operating costs, guiding with acceptable accuracy for local archaeologist digging and what to look for. The development of efficient methods in geophysical exploration, applied to different archaeological environments usually requires the crossing of different geophysical techniques. The methodologies for the application of geophysical surveys shall concern either in the steps of the data acquisition either in the steps of the obtained data processing and in the result representation. This work presents the results for two techniques, georadar and magnetometry, in different archaeological locations, showing the differences between the different archaeological sites, whose features are different.
