THE KARREN LANDSCAPES IN THE EVAPORITIC ROCKS OF SICILY.
2009
The karren in the evaporitic rocks of Sicily show wide distribution and variety of shapes relating to the large extension of the rocky outcrops, to the different lithofacies and to the climate. Karren features are largely present in all kinds of evaporites: macrocrystalline selenitic gypsum, detritic gypsum with various grain size, microcrystalline gypsum and in salts such as halite and kainite. Both the origin and the evolution of the karren are controlled by the dynamics of several processes such as solution and recrystallization, granular disintegration, carbonation, and phenomena linked to biological activity. The karren features have different dimensions, ranging from the nano- and the…
Il carsismo nei gessi della Sicilia
2018
Le aree carsiche gessose della Sicilia hanno attirato l’attenzione di naturalisti e geologi sin dalla seconda metà del 1800. Tuttavia, gli studi sul carsismo nei gessi non hanno visto una costante evoluzione nel tempo; infatti, dopo un lungo periodo di indifferenza, è solo a partire dagli anni ’80 del secolo scorso, che si è assistito ad un rinnovato interesse verso questa tematica, inizialmente grazie alla realizzazione di numerose campagne di esplorazione in diverse aree carsiche gessose della Sicilia da parte di alcuni gruppi speleologici siciliani, e in un secondo momento grazie all’interesse mostrato dall’Istituto di Geologia (oggi Dipartimento di Scienze della Terra e del Mare) dell’U…

Per una via siciliana dei gessi. Quando le parole portano alle cose
2023
Secondo il metodo Wörter und Sachen, parole e cose, suoni e referenti, devono essere studiati insieme. Questa simbiosi ha particolare necessità di essere applicata quando si tratti di cultura materiale. Il contributo è la storia di un’esperienza di indagine sul campo, svolta in un periodo di tempo di circa 15 anni, che ha riguardato le parole del gesso e le cose di gesso nella Sicilia centrale. L’individuazione di questo ambito di studio è stata parallela, ma marginale, rispetto ad una più significativa esperienza dialettologica relativa al lessico zolfifero. Eppure, grazie a questo approfondimento, sono emerse conoscenze inedite dal punto di vista linguistico ed etnodialettale, tali da avv…

Preliminary checklist of the Italian gypsophilous flora
2016
The richness and uniqueness of the flora growing on gypsum substrates in Italy is known since the XIX century (Macchiati, 1888). Furthermore, the concept of plant gypsophily can be defined as the exclusiveness (or virtually exclusiveness) for living in gypsum outcropping rocks. Thus only those plant species, which show preference – or even exclusivity - for gypsum substrates, would be classified as gipsophilous (Mota et al., 2011). The main aim of this research has been the elaboration of a checklist of the Italian gypsophilous flora. The study was made possible through international collaboration between the "Mediterranea" University of Reggio Calabria (Italy) and the University of Almería…
Evaporite karst in Italy: A review
2017
none 16 si Although outcropping rarely in Italy, evaporite (gypsum and anhydrite) karst has been described in detail since the early 20th century. Gypsum caves are now known from almost all Italian regions, but are mainly localised along the northern border of the Apennine chain (Emilia Romagna and Marche), Calabria, and Sicily, where the major outcrops occur. Recently, important caves have also been discovered in the underground gypsum mines in Piedmont. During the late 80s and 90s several multidisciplinary studies were carried out in many gypsum areas, resulting in a comprehensive overview, promoting further research in these special karst regions. More recent and detailed studies focused…
Wooden, gypsum and cork floor in the Sicilian construction tradition
2014
This presentation deals with a part of a wider and more complex outline of the Sicilian construction tradition characterised by the presence of gypsum technologies. Gypsum is a very common material used in the island for the realisation of all building elements; its use is commonly spread throughout Sicily thanks to several and wide superficial out crops located in some parts of the island that make this material very easy to find. This presentation is particularly focused on wooden and gypsum floors found and analysed during searches and surveys in the regional area. Outline on criteria for some consistent and appropriate consolidation and restoration interventions are here proposed.
