Aplicación de GPR para la reconstitución de niveles constructivos del poblado proto-histórico de Villasviejas del Tamuja (Cáceres)

Abstract

In this chapter, we present the results of Ground Penetrating Radar (GPR) survey carried out in Villasviejas del Tamuja, to complement the geophysical information already available in the project. To know with greater certainty the type of buried archaeological structures, a data collection methodology was used that allows processing intending to produce three-dimensional models of the subsoil. A total of 6 areas have been made peripheral to the two main enclosures of which the site is composed and where other surveys had previously been carried out using techniques such as magnetics. The team from the University of Évora used a 400 Mhz GPR GSSI prospecting approximately 2400 m2. This is a project carried out with a mesh but georeferenced with precision GPS. The three-dimensional models obtained identify the existence of different relevant reflectors in the subsoil at an approximate depth of 2.5 m. The lateral continuities revealed by some of these reflectors suggest that the archaeological structures that we interpret correspond to different types of well-preserved buildings. Together with these reflectors, we can see a diversity of other alterations with a poorly defined spatial distribution that we interpret must correspond to ancient structures. The method and equipment analysed, as well as the analysis of the different reflections detected, are described to give some interpretative guidelines based on the results.
