Geoarchaeology as a tool to understand ancient navigation in the northern Persian Gulf and the harbour history of Siraf
2020
International audience; Historical texts and archaeological studies attest to the maritime and trade importance of the Persian Gulf since the Sassanid Empires. Nonetheless, there is a paucity of data regarding ancient navigation and the reasons for a shift in m aritim e trade from the western (e.g. Shatt-al-Arab) to eastern (Siraf) Persian Gulf by the Abbasid dynasty. For som e scholars, Siraf was occupied between 360 and 977 CE, after which tim e an earthquake en-trained the dem ise of the city. However, it is unclear when Siraf was founded and how natural navigation conditions changed for ocean-going vessels in harbours of the NW Persian Gulf. To address this knowledge gap, we here presen…
Geomorphological environment: dunes in Agrigento coast
2008
[ITA] La fascia costiera di San Leone (Agrigento-Siclia). è costituita da una spiaggia sabbiosa delimítala verso terra da un complesso dunale di particolare pregio. L'assetto geomorfologico di questo litorale è stato inlluenzato dal forte grado di antropizzazione del luogo. La fascia costiera nel tempo ha súbito degli avanzamenti e arreiramenti. Sono stati quindi analizzati e proposti alcuni rimedi. mirali alia ricostruzione. al mantenimenlo e alia diíesa della duna.
Preservation of modern and mis 5.5 erosional landforms and biological structures as sea level markers: A matter of luck?
2021
The Mediterranean Basin is characterized by a significant variability in tectonic behaviour, ranging from subsidence to uplifting. However, those coastal areas considered to be tectonically stable show coastal landforms at elevations consistent with eustatic and isostatic sea level change models. In particular, geomorphological indicators—such as tidal notches or shore platforms—are often used to define the tectonic stability of the Mediterranean coasts. We present the results of swim surveys in nine rocky coastal sectors in the central Mediterranean Sea using the Geoswim approach. The entire route was covered in 22 days for a total distance of 158.5 km. All surveyed sites are considered to…
