Sicily
Opis:
North-Central Sicily represents an Apenninic-Maghrebian Chain sector, deriving from the Miocene- Pliocene deformation of different palaeogeographic domains-derived successions (carbonate platforms and pelagic basins), piled-up in ramp-flat and duplex style, and belonging during the Mesozoic-Tertiary to the Northern African Continental Margin. These domains are represented by outcropping basinal sedimentary successions (Imerese-Sicanian Basin), geometrically interposed between carbonate platform rock bodies: the Panormide (innermost) and the Hyblean-Pelagian Domains (more external). In this paper, using stratigraphic and structural data, we propose a new palaeogeographic model, in which the main differences from previous interpretations consist in the position of the Imerese Basin, here identified as the juncture between the Panormide Domain and the Sicanian Basin Auct., and the position of the Trapanese pelagic carbonate platform, considered as the juncture between the Hyblean-Pelagian Domain and the Sicanian Basin Auct. Tectono-sedimentary steps characterising the evolution of the Sicilian Miocene-Pliocene Foredeep illustrate the deformational history of the area. Two geological cross-sections depict the structural architecture of the tectonic edifice, characterised by different thrust sheets piled-up during the Miocene-Pleistocene time. The more external tectonic units are formed by elements deriving from the Plio-Pleistocene deformation of the northern margin of the Hyblean-Pelagian Domain. The "intermediate" tectonic units derive from the Miocene-Pliocene deformation of the Imerese- Sicanian Domain and the inner tectonic units are constituted by Panormide and Sicilide Domains-derived successions, deformed during the Miocene. A mostly neotectonics-related transcurrent faults reoriented the previous thrust sheets through NW-SE and W-E trending faults, producing large-scale positive flower structures which involved the geometrically deepest Hyblean-Pelagian substrate.

Opis:
In the present research, two neighbouring calanchi fronts have been monitored by means of repeated readings on erosion pins, that were carried out between November 2006 and October 2008. During the monitoring period, a gauge station has been recording rainfalls, allowing us to compute the Rainfall-Runoff Erosivity Factor of the USLE model. The research highlighted: i) a general correspondence between rainfalls temporal trends and surface variation rhythms; ii) alternating erosion and deposition phases result in a retreat of the "calanchi" fronts.

Opis:
Peter of Sicily, a Byzantine high official from the times of Basil I, intended to warn the Archbishop of Bulgaria against certain heretics, known as the Paulicians, as he learned during his mission to Tefrike about their plans of sending their missionaries there. His writings are regarded as the most competent source of information on the history and doctrine of the Paulicians. He also described some of their leaders, including Sergius himself. According to Peter, it was a woman with whom Sergius had had an affair who made him the devil’s tool. He accepted the name of Tychicos and passed himself off as a disciple of Paul the Apostle. For 34 years he was the leader of the Paulicians. Peter admits that Sergius was successful in winning followers and at the same time, besides making false statements, accuses him of selling Christians into slavery to barbarians and of collaboration with the Muslims. In the end, however, he was supposed to have an argument with another heresiarch, Baanes, which would lead to a break among the Paulicians. Sergius is colourfully described as an enemy of the Cross, a voice of impiety, a lover of darkness and a wolf in sheep’s clothing, who skilfully pretends to be a man of virtue but has deceived many. Although he himself was murdered in 834/835, his work was continued by disciples of his.

Opis:
The outbreak of the Spanish Civil War represented a pivotal moment in Leonardo Sciascia’s ideological development, as it pushed him towards an anti-fascist passion that would make him an engagé writer over the years. In fact, the news of Lorca’s assassination and Ortega y Gasset’s volumes had a lasting influence on the writer: he began to read Spanish and about the Spanish world, thus discovering Spain and its language, literature, and culture. In fact, it was a rediscovery, since, in the eyes of the Sicilian author, the common Arab domination and the long Spanish hegemony in Sicily had already connected the island and the peninsula in an intricate web of “similarities.” The present article aims to examine the distinctness of Sciascia’s Sicilian-Spanish imaginary that is present in the reports that he published after his numerous trips to the Iberian land starting in the 1950s. After having often been dismissed as paraliterary, those works will be analysed as travel writing so as to better appreciate them. Ore di Spagna, the volume that collects most of those journalistic articles, will be considered as one of the best examples of reporting in the 20th century, far beyond the boundaries of essay production.
Lo scoppio della Guerra civile spagnola rappresentò un momento decisivo per la maturazione ideologica di Leonardo Sciascia, in quanto le sue vicende lo spinsero verso quella passione antifascista che nel tempo lo avrebbe reso uno scrittore engagé. Tuttavia, dal triennio rivoluzionario arrivarono anche le notizie dell’assassinio di Lorca, i volumi di Ortega y Gasset - su cui Sciascia iniziò a leggere il castellano, e poi il mondo -, dunque la scoperta della Spagna, della sua lingua, della sua letteratura e della sua cultura. In realtà, si sarebbe trattato di una riscoperta, poiché, agli occhi dell’autore, la comune dominazione araba e la lunga egemonia spagnola in Sicilia avevano già saldato l’isola alla penisola in un intricato intreccio di “somiglianze”. Il presente studio intende esaminare le peculiarità di questo immaginario siculo-spagnolo attraverso una presentazione dei reportage pubblicati da Sciascia a seguito dei numerosi viaggi intrapresi in terra iberica a partire dagli anni Cinquanta. Trattandosi di pagine spesso allontanate dal genere che meglio può valorizzarle, si procederà, infine, a una loro valutazione in chiave odeporica e si stabilirà che Ore di Spagna, il volume che raccoglie la maggior parte di quei pezzi giornalistici, può superare i confini del compendio saggistico nella direzione dei migliori esiti reportistici novecenteschi.

Opis:
Ephemeral gullies (EGs) are channels of different sizes refilled by tillage equipment normally used on farms. In this paper, the data-set collected from 1995 to 2007 in a wheat--ultivated area in Raddusa (Sicily, Italy), having a surface of almost 80 ha, were used to analyze the morphological characteristics of EGs. The measurements show an high temporal variability in EG characteristics. The EG measurements and the rill erosion measurements carried out in 15 plots located in the experimental "Sparacia" area (Sicily), demonstrated that a morphological similarity condition exists between rills and ephemeral gullies. The occurrence of step-pool structures in an EG occurring in the observation period in the same place allows to conclude that, in the considered environment, an ephemeral channel, such an EG, similarly to a stream, tends to reach a step-pool morphology as the structure that maximises its stability.

A GIS+analysis was carried out in a test basin of southern Sicily, the Magazzolo River basin, in order to assess susceptibility conditions to gully erosion phenomena. The linear density of ephemeral and permanent gullies computed within each class of nine environmental variables was used to generate a gully erosion susceptibility map for the area. A validation procedure carried out in order to test the reliability of the adopted method highlighted a clear correlation between the occurrence of gullies and the computed susceptibility levels.

Opis:
Western Sicily represents a fragment of the Apenninic-Maghrebian Chain, largely built during the Miocene and formed by a set of tectonic units with southern vergence of folds and ramp-flat style of thrust surfaces. The thrust tectonics-related structures are displaced by a high-angle fault system, which bounds the main Mesozoic "carbonatic massifs" and generally interpreted as a neotectonic dip-slip extensional tectonics-related faults. The present paper, with the support of mesostructural analysis, presents an important Plio-Pleistocene strike-slip tectonics, represented by high-angle net- and strike-slip fault system. Different scale flower structures and associated fold systems, which cut the Miocene tectonic units, characterise the areas along the main transcurrent fault zones. Strike-slip neotectonics is mostly represented by right-lateral NW-SE/W-E and left-lateral N-S/NE-SW transcurrent faults, which may represent a W-E trending deep-seated Riedel system connected to the Tyrrhenian spreading. The NW-SE first order synthetic structures appear to control the opening of several rhomboidal tectonic depressions located in north-western Sicily and its offshore, and are counteracted by W-E trending transpressional structures located in the central Sicily mainland. An attempt at semi-quantitative restoration shows the neotectonic evolution of north-western Sicily during the Pliocene and Pleistocene, characterised by the progressive activation towards the east of en-échelon strike-slip fault strand, in an overall horsetail splay geometry, which produced releasing bends in off-shore and restraining bends in the mainland.

Opis:
Islam jawi się dziś jako nietolerancyjna religia pozostająca w konflikcie z tradycją judeochrześcijańską. Jednak przykład średniowiecznej Sycylii dowodzi, że w imię Koranu można zbudować wielokulturowe społeczeństwo. Strategiczne położenie Sycylii od wieków przyciągało osadników. Od VI wieku władało nią Bizancjum. W VIII wieku wyspa zainteresowała Arabów tworzących nowe państwa w Afryce Północnej. Jednym z nich był emirat Aghlabidów. W 827 roku wyruszyła stamtąd armia, rozpoczynając muzułmański podbój Sycylii, który - pod znakiem rzezi i zniszczeń - trwał przez kolejne dziesięciolecia. W X wieku władzę na wyspie przejęła dynastia Kalbidów. Wprowadzili oni politykę tolerancji, dbali o rozwój nauki i kultury, wspierali rolnictwo oraz handel. W XI wieku Sycylię podbili Normanowie. Zetknąwszy się z wysoką kulturą wyspy, utrzymali oni większość rozwiązań poprzedników. Językami urzędowymi były łacina i greka, a także arabski. Z połączenia różnych kultur powstało jedno z najnowocześniejszych społeczeństw tamtych czasów.
Islam today is being perceived as the religion that is in the state of conflict with the Judeo-Christian tradition. But a case study of the medieval Sicily proves that it is possible to create a multicultural society in the name of the Koran. Strategic location of the island has always attracted settlers. It was under Byzantine rule since the 6th century. In the 8th century it attracted the attention of the Arabs, just then creating their new states in North Africa. One of them was the Aghlabid Emirate. In 827 it sent an invading army to Sicily. The Muslim conquest of the island, punctuated with the outbursts of onslaught and destruction, lasted for several decades. In the 10th century the reins of power went to the rulers from the Kalbids dynasty. They introduced a policy of tolerance, promoted arts and science and supported trade and agriculture. In the 11th century Sicily was conquered by the Normans. Recognising the high value of the culture they encountered on the island, they retained most measures of their predecessors. The official languages were Latin, Greek and Arabic. The mixture of various cultures in Sicily produced one of the most advanced societies of that period.

At Akrai in southeastern Sicily, the University of Warsaw excavations have unearthed a huge quantity of small, wheel-made, beige-slipped lamps belonging to the Roman Republican type Ricci C. The most important conclusions from the research concern the functionality of these lamps, both as devices used for lighting in everyday life and as unused elements of votive deposits, as well as their enduring presence in southeastern Sicily when they had all but disappeared elsewhere in the Roman world. The type is a derivative of an old form and peaked in popularity in the 3rd and 2nd centuries BC. The last examples of this type seem to have been produced in the reign of Augustus.

In this study pollen grains of 13 cultivars and 3 rootstocks belonging to 5 species (P. armeniaca, P. domestica, P. dulcis, P. persica, P. avium) of the genus Prunus collected from North-East Sicily were examined for the micromorphological characterization through the scanning electron microscopy (SEM). The length of polar axis (P) and the equatorial diameter (E) of grain, P/E ratio, the length of colpi (C), diameter of perforations (DP) and the number of perforations in 25 μm2 (PN), the width of muri (WM), the distance between muri (DM) and their number in 25 μm2 (MN), the width of grooves (WG) were measured and their variation was compared among studied taxa. Moreover multivariate statistical analysis was carried out to distinguish morphometric information from measured parameters. All pollen grains are trizonocolpate, isopolar, medium-large sized and their shape varies from prolate to perprolate. Regarding outline pollen grains are subtriangular in polar view and elliptic in equatorial view. Exine sculpturing is striate with perforations on grain surface. The arrangement of ridges appears roughly parallel but too sloped (sometimes curved) compared to polar axis, or branched and oriented in different directions, or perfectly parallel or more irregular with bifurcated ridges often sinuous. The analyses showed a great variability (particularly in P. domestica cultivars) related in some cases to the diversity in the morphological features of the leaves and the fruits of the investigated entities.

Opis:
Terravecchia Formation in the Scillato Basin is a good example of development of a post-tectonic basin. Practically continuous exposures across that basin give the rare possibility to observe the lateral distribution of lithofacies and gradual changes of sedimentary succession from an alluvial fan, fluvial plan to lacustrine and, eventually, to marine setting. The alluvial fan deposits are generally represented by polymictic, disorganised or crudely organised conglomerates representing mainly flow and debris flow deposits. The fluvial plain association is characterized generally by cross-bedded sandstones with streaks of conglomerates laid down within a channel bar system. Flood-plain deposits are subordinate. Sedimentary structures suggest deposition in a braided river. The fluvial plain association pass laterally to lacustrine/fluvial plain deposits represented by grey to pinkish mudstones with channelised sandstones. As an effect of subsidence the Scillato Basin was invaded by marine/brackish environment, and marly mudstones and siltstones with subordinate sandstones were deposited. That variability of sedimentary facies can be explained by vertical tectonic movements.
Późnomioceńska formacja Terravecchia zachowana w basenie Scillato, stanowi dobry przykład rozwoju basenu posttektonicznego. Ciąg bardzo dobrych odsłonięć w poprzek basenu pozwolił na szczegółowe obserwacje rozkładu litofacji, struktur sedymentacyjnych oraz asocjacji facjalnych i ich wzajemnych związków. Wyróżnionych zostało kilka środowisk sedymentacyjnych, od stożka aluwialnego, przez rzekę roztokową po środowisko jeziorne i morskie. Osady stożka aluwialnego reprezentowane są przez czerwone i żółte, polimiktyczne zepieńce, o strukturach zarówno bezładnych jak i uporządkowanych, powstałe w wyniku działania prądów i spływów rumoszowych. Osady rzeki roztokowej to głównie przekątnie warstwowane piaskowce związane z różnego rodzaju łachami piaszczystymi. Mułowcowe osady równi zalewowych zachowały się tylko sporadycznie. Osady rzeczne przechodzą lateralnie w mułowcowe osady jeziorne z licznymi osadami kanałowymi w ich dolnej części. Pod koniec rozwoju basenu, w rezultacie subsydencji tektonicznej, nastąpiła ingresja morska i powyżej osadów rzeczno-jeziornych rozpoczęła się sedymentacja osadów brakiczno-morskich z poziomami fauny.

Opis:
Neptunian sills at Rocca Busambra, a fragment of the Trapanese/Saccense Domain in western Sicily, host the most abundant ammonite and gastropod fauna which has ever been recorded from the Jurassic of the western Tethys. The fauna is dominated by parautochthonous organisms which were swept into the sills by gentle transport. Ammonites are characterized by perfect preservation and small size, a feature which is due to the predominance of microconchs but also of stunting. The most complete sill is 0.7 m thick and could be separated into 17 levels which range in age from the early Toarcian into the late Kimmeridgian, thus representing the most extreme case of palaeontologically and depositionally documented stratigraphic condensation in Earth history. The unique feature of the Rocca Busambra sills is due to the interaction of three processes: extreme stratigraphic condensation on the sea floor, weak tectonic fracturing of the host rock and repeated reopening on top of already existing sills. Contrasting percentages of gastropods in individual levels reflect sea-level oscillations which correspond to long known low- and highstands during the Jurassic of the western Tethys. Comparisons with other ammonite-bearing sill faunas reveal several similarities, but represent only short-timed phases of tectonic pulses and deposition.
