Prospección con GPR (Ground Penetrating Radar) en el cementerio de la Misión Salesiana, Río Grande (Tierra del Fuego, Argentina)

Abstract

This paper describes the geophysical survey through GPR (Ground Penetrating Radar) in La Misión Salesiana cemetery, close to Río Grande city (Tierra del Fuego, Argentina). It is situated over the Holocene beach reach plain composed with low angle interstratifi cations of gravel and sand. A 400 MHz antenna of the SIR 3000 model is the tool used for the survey. The main goal is to detect anomalies that allow corroborating the presence, orientation and dimension of the wood coffi n found during a previous test pit, associated with burials of the late nineteenth and early twentieth centuries. This contribution represents a trial detailing the results obtained during the second season where the surveyed area was previously known from the presence of a burial. These results provide the basis for further exploration tasks in other sectors of the cemetery from which the use of this methodology will reduce the area to dig with traditional archaeological methods.
