Small scale prehistoric archaeological sites, such as the Fumane cave, located north of Verona city in north Italy, poses a lot of challenges both to archaeologists and geophysicists. The cave is considered as one of the most important Middle and upper Prehistoric sites of Europe, discovered in 1884. It contains a wellpreserved and impressive stratigraphic sequence of more than 12m thick where human activity remains are accumulated. In this work, we applied high resolution geoelectrical resistivity tomography and seismic passive geophysical methods to investigate, on one hand, the electrical properties of the shallowest part of the deposit, where, a number of medium to low resistivity anomalies were localised. On the other, a test using microtremors provide evidences on the probable maximum thickness of the deposit (4-5 m). In addition a high resolution and georeferenced laser scanner survey was carried out so as to have an high resolution topographic model that shall be used as a container to allocate in 3D the position of the already achieved findings as well as the geophysical results. This shall constitute the first step for the planning of a smart protocol for results conservation and dissemination both for cultural and scientific interests.

Abstract
Small scale prehistoric archaeological sites, such as the Fumane cave, located north of Verona city in north Italy, poses a lot of challenges both to archaeologists and geophysicists. The cave is considered as one of the most important Middle and upper Prehistoric sites of Europe, discovered in 1884. It contains a wellpreserved and impressive stratigraphic sequence of more than 12m thick where human activity remains are accumulated. In this work, we applied high resolution geoelectrical resistivity tomography and seismic passive geophysical methods to investigate, on one hand, the electrical properties of the shallowest part of the deposit, where, a number of medium to low resistivity anomalies were localised. On the other, a test using microtremors provide evidences on the probable maximum thickness of the deposit (4-5 m). In addition a high resolution and georeferenced laser scanner survey was carried out so as to have an high resolution topographic model that shall be used as a container to allocate in 3D the position of the already achieved findings as well as the geophysical results. This shall constitute the first step for the planning of a smart protocol for results conservation and dissemination both for cultural and scientific interests.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
