Evidence of Middle and Upper Pleistocene shorelines in the area between Capo Mongerbino (Bagheria) and Piano Sperone (Altavilla Milicia), NC Sicily
2006
In the coastal tract between Capo Mongerbino (Bagheria) and Piano Sperone (Altavilla Milicia), some forms (caves, terraces, erosional surfaces) of marine origin and of remarkable morpho-tectonic importance have been located. The caves lie at different altitudes ranging from about 200 m a. s. l. (Grotta Mazzamuto) to 7 m a. s. l. (Cala dell’Osta); the terraced areas, comprised between 0 and 200 m a. s. l., are arranged in five orders. In Sicily, the coexistence of both glacial-eustatic cycles and a slow uplift, caused by the Pleistocenic tectonics, resulted into the sea showing itself under different forms at different altitudes, presumably dating back to Middle Pleistocene. The age of each …
Plio-Quaternary coastal landscape evolution of north-western Sicily (Italy)
2023
We present and discuss the results of a geomorphological and geological study aimed at reconstructing the Plio-Quaternary evolution of the NW Sicily coastal belt, a low strain rate region in the central Mediterranean Sea. We performed morphometric and field analysis of Quaternary marine terraces extracting more than 300 shoreline location points subdivided into six orders. The obtained dataset was validate by investigating the morphological changes along topographic profiles and comparing the extracted locations and elevations with the stratigraphic boundaries in the Plio-Quaternary units. We distinguished two contiguous coastal sectors characterized by different paleo-shoreline elevations …
Analisi dei processi di rinaturalizzazione nei vigneti e cappereti abbandonati del paesaggio terrazzato di Pantelleria (Canale di Sicilia)
2004
This study analyses the vegetation dynamics in the terrace landscape of Pantelleria Island (Sicilian Channel). The main questions were to determine the sequence of plant communities in time and to find out which environmental factors influence the course and the speed of succession. In the thermomediterranean part of the island were made vegetation relevés in five different fallow age classes, investigating three different ecological subunits: the terrace surface, the wall base and the wall in North-facing as well as in South-facing vine and caper fallows. The results show that undisturbed abandoned terraces are subject to rapid renaturation: 50 to 80 years old fallows are covered by dense …
International Symposium on Greener Cities for More Efficient Ecosystem Services in a Climate Changing World
2018
The idea of garden is expressed, for the first time in history, by the Mesopotamian civilization as early as the IV millennium BCE as drawings and poetry texts showing a wall fencing one single tree. This is the first representation of the idea of sheltering/protecting a tree by human artifacts and, in its simplest form, brings the idea of the tight relationship between horticulture and urban environment. The "jardinu" of Pantelleria, a drystone wall shaped into an open-top tower encircling a single citrus tree, fully matches both in its founding idea and its physical implementation the elemental idea of the Mesopotamian garden. Such traditional growing system, developed in Pantelleria to c…

An exceptional rocky shore preserved during Oligocene (Late Rupelian) transgression in the Upper Rhine Graben (Mainz Basin, Germany)
2012
The Early Oligocene (Late Rupelian) Alzey Formation (Mainz Basin, Upper Rhine Graben, Germany) records the development of a rocky coast depositional system during transgression. The formation unconformably overlies Permian bedrock across a composite transgressive ravinement surface. Exposure of the surface shows a succession of subplanar bedrock terraces, separated by near-vertical risers. Terraces show a broad staircase geometry and display wave-erosional features (notches, sea stacks, furrows). Detailed sedimentological and palaeoecological investigations reveal prograding beachface and shoreface depositional units that overlie terraces and are adjacent to risers. Terraces are interpreted…

An erratic dropstone of granodiorite with a water-escape structure from a Weichselian terrace along the River Gauja (NE Latvia)
2016
Abstract A river terrace of the River Gauja (Latvia), built of Weichselian glaciolacustrine deposits, contains a large number of erratic boulders from the Fennoscandian Shield. These erratic boulders include several types of granites and granodiorites. Some of the granodiorites are so strongly weathered that they fall apart into mm-sized grains of individual minerals when it is attempted to take them out of the host sediment. This strongly weathered nature makes them physically comparable to unconsolidated sand. A consequence is that they may be subjected to soft-sediment deformation. The erratic granodiorite boulder under study here is the first described to show such a soft-sediment defor…
Dix ans d'archéologie forestière dans le Châtillonnais (Côte-d'Or) : enclos, habitats, parcellaires
2010
National audience; Ces recherches sur les ensembles de structures de pierre sous forêt sont mises en œuvre depuis dix ans et sont inté- grées depuis 2003 dans le P.C.R. ‘Vix et son Environnement', dirigé par C. Mordant, S. Wirth et B. Chaume. Les vestiges étudiés sont implantés dans deux milieux géographiques distincts mais contigus : le plateau calcaire recouvert par la forêt domaniale de Châtillon, et les rebords de la Digeanne et du Brevon qui entaillent ce plateau à l'est et au sud. La prospection présente ici des caractères particuliers liés au couvert forestier. Les relevés G.P.S. sont intégrés dans un S.I.G. et constituent la base de cette étude, dans un va et vient…
