To enhance the knowledge of the unexcavated portions of the archaeological site and to locate the position of the unknown buried structures, geophysical prospections employing the Ground Penetrating Radar method were performed between September and November 2017. For the measurements, a GPR system SIR3000 (GSSI), equipped with a 400 MHz bistatic antenna with constant offset was employed to survey 18 different sectors closing to few excavated area. Taking into account the environmental conditions of the site and the nature of the hypothesized structures, some areas have been surveyed with a...

Over the past two decades, the use of LiDAR has found increasing popularity in archaeology due to its capability to penetrate the vegetation cover, thus providing information in areas were other technologies are ineffective and in places where field surveys are particularly difficult, such as areas with dense vegetation. Nevertheless, despite the recognized effectiveness of LiDAR, its capability for archaeological prospection could be strongly limited by very dense vegetation cover, and, in these cases, the data processing and analysis requires special attention. In this paper, to improve...

In this contribution we will show the combination of different migration results calculated on the same Bscan. This allows to account for the variation of the propagation velocity in the soil below the measurement line. Horizontal and vertical variations of the propagation velocities will be considered. A validation vs. real data will be provided, in a case where reinforced concrete was tested.

Portable instrumentation is largely used in archaeometry for in-field measurements at museums and archaeological sites. The historic evolution of pigments is closely related to the technology developments in past cultures and provides relevant clues regarding their knowledge advancement. Here, a systematic study of 26 historical powdered pigments was carried out through a combined handheld instrumentation for X-ray Fluorescence. Chemical identification was carried out through a set of instrumentation produced by different manufacturers. Their performances are compared on the same set of...

In the last decade portable devices for analyzes on Cultural Heritage (e.g. laser-scanners, spectroscopes, XRF) has reached levels of reliability such as to be able to replace benchtop instrumentation for survey in situ. One of the most effective application of these devices concerns the digitization and the diagnosis of artworks preserved inside museums. Indeed, moving art objects or finds from its place of preservation to specific laboratories can often result difficult due to several reasons as fragility, big sizes, risk of damage, lack of authorizations etc. The paper shows the results...

As part of the Pandosia Anglona Project, of which the Institute of Cultural Heritage Sciences (CNR) is a partner, geophysical investigations were carried out with the aim to identifying structures of archaeological interest. The investigation area is located on the right of the road that connects Policoro with Tursi, on the top of a hill 262 m a.s.l. The Anglona hill dominates the lower valley of the Agri and Sinni rivers rising in the middle of the hilly system that divides the two rivers, at almost equal distance between these two streams. Geophysical investigation method geoelectrics was...

The Santa Caterina tower in Nardò (Lecce, Italy) represents one of the many types of coastal towers of the ancient Terra d'Otranto province. It was part of the defensive system of the Ionian coast of Salento against the Turkish threat. The integrated geophysical prospections are part of the analysis of the tower about constructive elements, wall discontinuities, functional modification in order to understand the phases and the change of the structure over the centuries. The information collected will be useful for a restoration project finalized to recover a building abandoned for years.

Seismic tomography, seismic refraction tomography and electrical resistivity tomography (ERT) imaging was employed to make diagnosis for an very important archaeological cave named Grotta della Poesia. Rock fracturing and destructive force of sea waves causes structural instability in the roof of the cave that has partially collapsed. The inside geometry of fractures and the physical parameters of the surrounding and underground materials were the primary objectives of the geophysical survey. Seismic and ERT data were acquired along one horizontal profile on the roof of the cave. The...

In this paper the results of a GPR prospecting performed in the cathedral of Acerenza (Basilicata, southern Italy) are proposed. The investigation was aimed in particular to search, if any, traces of the tomb of St. Canio with his bones, protector of the town of Acerenza. Data processed with GPRslice code have been 3D shaped to define the position, depth and volume of the tomb. The results are also in agreement with the historical sources that indicate the probably burial place.

The dynamic identification of structural damage for masonry constructions could play a crucial role for the preservation of architectural heritage. The interest is this experimental technique is motivated both by its non-destructive nature and by the possibility of assessing the damage at an early stage. In this context, this paper studies the damage identification of a full-scale parabolic tuff barrel vault subjected to differential settlements of the supports starting from vibration measurements. The geometry of the vault (polycentric near parabolic shape) and the masonry material (Apulian...
