| Description: |
The Neolithic settlement of Favella della Corte (Cosenza, Southern Italy) provides an important opportunity to investigate prehistoric Southern Italian communities. This work presents the results of sedimentological analysis on outcropping stratigraphic units coupled with a non-invasive geophysical investigation of the site. Specifically, a multi approach geophysical survey has been conducted, including magnetic field measurements, magnetic susceptibility sampling and electrical resistivity profiling. This study aims to provide a detailed characterisation of the site’s shallow stratigraphy and to support the reconstruction of its paleo-environmental context. The magnetic survey consisted of approximately 3,000 measurements acquired over an area of 11,600 m2 using a Scintrex MP3 Proton Procession Magnetometer (PPM). Magnetic susceptibility was measured on exposed stratigraphic units along vertical sections, with sampling intervals of 20–50 cm, using a portable Geofyzika KT-5 kappameter. Electrical resistivity data were collected along nine profiles spaced 20 m apart, each extending up to 90 m in length. Measurements were carried out using a geo-resistivimeter designed and built by the Applied Geophysics Laboratory of the University of Genova. Sedimentological analyses revealed the alternation of three shallow levels: (i) an upper arable layer, (ii) an intermediate silty sand layer, and (iii) a deeper silty-sandy gravel layer. Magnetic susceptibility data supported this evidence, highlighting a contrast between the more susceptible intermediate horizon and the underlying gravel level. Therefore, the magnetic inversion was constrained to a single layer of prismatic bodies, enabling the reconstruction of the interface between silty sand and silty-sandy gravel units. Because of the non-linearity of the inverse problem, the L-BFGS algorithm has been employed to solve the optimization problem. The model parameters involved are the depth of the bottom of each prism and a single value of magnetic susceptibility contrast ... |
