- PublicationRestrictedLate Quaternary benthic foraminiferal and ostracod response to palaeoenvironmental changes in a Mediterranean coastal area, Port of Salerno, Tyrrhenian Sea(2020)
; ; ; ; ; ; ; ; ; ; ; ; ; ; ; The Late Quaternary benthic foraminiferal and ostracod assemblages from two continuous cores drilled in the Port of Salerno were studied to define their relationship with geochemical characteristics of the sediments and with the palaeoenvironmental evolution. The succession, ranging from Late Pleistocene to the 20th century, recorded the transition from a marine coastal environment under natural conditions to a depositional context affected by anthropogenic influence. In the lower part of the sequence, ecological and sedimentary changes were linked to sea-level changes due to Late Quaternary climatic phases, as well as to volcanic events such as the Campanian Ignimbrite eruption, represented by levels with high metal (Fe, Mn, Pb, Zn) concentrations, possibly leading to low pH phases. Later human activities, such as the construction of harbour facilities in the 18th century and the industrial development in the 19th century, influenced environmental variations, as shown in the upper part of the succession. High levels of heavy metal concentrations (Co, Cu, Fe, Pb, V) recorded in layers deposited in the 1800s suggest the presence of a pollution event which could be linked to manufacturing activities and might have occurred during the first part of the 19th century. Calcareous meiofaunal assemblages showed high diversity values, probably due to the occurrence of "rare short lived" species in an unstable environment. Assemblages were dominated by the foraminiferal species Ammonia aberdoveyensis and Haynesina depressula, and by the ostracods Pontocythere turbida and Semicytherura sulcata, which are considered as possibly stress-tolerant species.67 2 - PublicationOpen AccessMagnetotelluric measurements in the Monte Amiata region(1994-11)

The one-dimensional (1D) resistivity inversion shows a low resistivity zone characterized by high heat flow. Based on 1D resistivity information, detailed two-dimensional (2D) resistivity modelling was carried out. A reasonable 2D resistivity model was proposed for shallow depths, and was found to be in good agreement with the available geological and geophysical information on the area. The present results show a low resistivity anomaly, characterized by high heat flow. The anomaly seems to extend beyond the classic Mt. Amiata geothermal region.164 185 - PublicationOpen AccessIntegrated geophysical survey to recognize ancient Picentia’s buried walls, in the Archaeological Park of Pontecagnano – Faiano (Southern Italy)(2008-10)

G.; Dipartimento di Scienze della Terra, Università degli studi di Napoli «Federico II», Napoli, Italy; ; ; ; ; ; There is no information on previous geophysical prospections carried out in the Archaeological Park of Pontecagnano- Faiano, in order to reconstruct the ancient settlement of Picentia, an Etrusco-Campanian and Roman settlement near Salerno (Southern Italy). Therefore, an integrated geophysical survey based on magnetic, geoelectric and ground-penetrating radar (GPR) prospections was executed in the Park. The methods provided a basic map of buried ancient structures at depth from 0.1-0.2 to about 1.5 meters. Magnetic data were processed analyzing the analytical signal of the vertical derivative of the measured gradient and this substantially reduced a strong fence effect. The results of the geophysical prospections showed archaeological structures located close to those discovered in the excavated areas. The shape of the anomalies are usually elongated with well-defined geometrical characteristics. Many anomalies are arranged along orthogonal directions and they are very coherent with the excavated structures, namely the quarters structures of the ancient Picentia.470 678
