Muri#Monasteri#Mattoni - La città degli Uomini e delle Donne- La storia costruttiva di Palazzo Murena, 2020

La ricerca, di tipo multidisciplinare, è iniziata con l’indagine geologica del sito di edificazione per poi proseguire con ricerche di tipo archivistico, storico ed architettonico. L'acquisizione di nuove ed inedite informazioni ha permesso di ricostruire le vicende di quasi mezzo secolo, evidenziando un profondo legame fra l’edificio, le risorse del territorio ed i suoi abitanti. In conclusione l’interdipendenza fra ambiente ed uomo ha fornito informazioni del tutto inaspettate sia sulla storia dell’Ateneo che dell’intera città di Perugia."
The Norian/Rhaetian boundary interval at Pignola-Abriola section (southern Apennines, Italy) as a GSSP candidate for the Rhaetian stage: an update

The Villas, built in the middle of the 4 th century, includes a hexagonal structure, about 30 meters in diameter, decorated with painted wall plasters and beautiful figurative floor mosaics. The structure is equipped with apsed rooms (at least 5), exhibiting similarity with some monumental triclinia of Constantinople and Rome. Archaeometric analyses have been carried out on mortars, stones and vitreous tesserae, with the aim to identify the raw materials and support the archaeological investigation about cultural models and economic status of the aristocratic owner in the Late Roman Tuscany. Mortars samples from different building units of the Villas have been studied through minero-petrographic and thermogravimetric methods. Stone tesserae have been analyzed by minero-petrographic and sedimentologic methods, to obtain information on the provenance of the raw materials used. Finally, Raman spectroscopy and SEM-EDS analyses have been performed on vitreous tesserae, to obtain information on colouring and opaquening agents. The studies carried out on the building elements suggested that, in spite of iconographic and architectural models proper of the great Mediterranean villae, local and spolia raw materials were used in this great construction work.
Upper Triassic radiolarian assemblages from the Monte Volturino section (Lagonegro Basin, Southern Italy) to date volcanoclastic calcarenitic horizons

No fossils other than radiolarians can be obtained from the strata. Based on the phyletic evolution of Aurisaturnalis and Turbocapsula, two radiolarian zones for the Barremian to Aptian interval have been defined: the Aurisaturnalis carinatus Zone and the Turbocapsula costata Zone. This zonal scheme can be used for identifying episodes, such as OAEs, in the pelagic realms (LI et al., 2017).
Jurassic radiolarians from the Lagonegro Basin (Southern Apennines, Italy)

Le tre successioni prese in esame sono quelle di San Fele, Pignola e Sasso di Castalda; queste successioni sono state riferite, su base litostratigrafica, rispettivamente a facies prossimali, intermedie e distali. Di queste successioni e stata effettuata un'analisi biostratigrafica delle associazioni a radiolari presenti, analizzando e comparando la parte giurassica, caratterizzata dalla formazione degli Scisti Silicei (Retico-Giurassico Superiore). Questa formazione e costituita da selci a radiolari, radiolariti e argilliti rosse e verdi, con intercalazioni calcarenitiche, piu o meno potenti e abbondanti, in funzione della posizione delle successioni rispetto alle adiacenti piattaforme carbonatiche che bordavano a nord il Bacino Lagonegrese. Il contenuto paleontologico di questa porzione di Scisti Silicei e rappresentato quasi esclusivamente da faune ...
Paleogeographic meaning of the Late Triassic - Early Jurassic Lagonegro units

The distal ones (Madonna del Sirino, Lagonegro succession) are made by the Calcari con Selce fm (late Ladinianlate Norian) and by the Scisti Silicei fm (Rhaetian-Tithonian). Reworked calcarenites are rare and the Scisti Silicei fm is very condensed. In the intermediate facies (Sasso di Castalda, Pignola), the Calcari con Selce fm is sometimes dolomitized; the Scisti Silicei fm contains calcirudites and coarse grained calcarenites. In the proximal facies (M. Pierno, S. Fele). the Calcari con Selce fm and the lower part of the Scisti Silicei fm are replaced by thin-bedded, cherty dolostones followed by massive dolostones (Norian to Toarcian). This dolostones are a transitional element between the typical Lagonegro facies and the Molise facies (Mt. Marrone). The Scisti Silicei fm (Middle and Late Jurassic) contains a large amount of calcarenites and calcirudites. The sedimentary environment was a deepen...

The Late Triassic cherty dolostones of Mt. Marrone (Mainarde range) as part of the Molise basin

Marrone (Mainarde range-southern part of the Abruzzi National Park) starts with thin bedded cherty dolostones, suggesting deposition in a pelagic basin; radiolarians indicate a Late Triassic age. These dolostones are similar to the cherty dolostones of the Frosolone 2 well (Molise basin). The cherty dolostones of Mt. Marrone are followed by massive and nodular dolostones of proximal basin environment. Partially dolomitized nodular limestone, with radiolarians and thin shelled pelecypods, overlies the massive dolostones. The upper part of the succession contains radiolarites, calcirudites, shales and cherty calcarenites; its age is Barremian-Aptian. Many pebbles in the calcirudites come from a shallow water carbonate platform, a minor amount being of basinal facies; their ages span from Dogger to Early Cretaceous. Their presence suggests the occurence of synsedimentary (extensional) faulting. The close resemblance between the Mt. Marrone succession...
Triassic-Jurassic stratigraphy of the Madonna del Sirino succession (Lagonegro Basin, Southern Apennines, Italy)

The aim of this study is to obtain more information about the evolution of this basin during the Late Triassic-Early Jurassic interval. The section of Madonna del Sirino begins with cherty limestones (upper part of the Calcari con Selce fm), passing upwards to radiolarites and shales (Scisti Silicei fm) through a "transitional interval". The Scisti Silicei fm is divided in four members: a) "Buccaglione" with red shales, radiolarites and two anoxic levels; b) "Nevera" with black shales and black cherty layers; c) "Serra" with red radiolarites and red shales; d) "Acqua Sulfurea" with green radiolarites and green chert. New biostratigraphic data provided elements for referring some events to specific ages. A conodont assemblage allows us to assert that the change from calcareous to siliceous deposition did not begin before the Sevatian....
