Texte intégralActive Normal Faulting (NF) affects the carbonate rocks of the Italian central Apennines since Late Pliocene causing destructive earthquakes and, together with regional uplift, controlling the development of Deep-Seated Gravitational Slope Deformations (DGSDs). The latter are often located in the footwall of active normal faults. The principal slip surfaces and associated slip zones of DGSD and NF exhume from different depths (100-500 m for DGSDs, 1-3 km for NFs), and are formed and active over a different range of temperatures (< 30 °C for DGSDs vs. 0-100 °C for NFs), pressures (< 15 MPa for DGSDs, 0-80 MPa for NFs) and slip rates (usually < 10-3 m/s for DGSDs, up to ~ 1 m/s for NFs). Such large differences in loading conditions should result in the formation of distinctive secondary fault/fracture networks in the damage zones that host the DGSDs, possibly recognizable at the outcrop scale, or in the slip zones microstructures. The individuation of the deformation mechanisms and the discrimination between DGSDs and NFs structures could bring outstanding improvements in geological hazard studies. To achieve these goals, I investigated four DGSDs located in the footwall of active seismogenic NFs and three normal faults bordering large and small depressions in the central Apennines. I investigated the fracture distribution around DGSDs’ and NFs scarps and the microstructures of the associated slip zones. Then, I performed Crystallographic Texture Analyses (CTA) on natural and experimental slip zones in carbonate rocks to identify the Crystallographic Preferred Orientations (CPOs) of microcrystalline aggregates and interpret the deformation mechanisms active during slip. Based on these studies, I conclude that most DGSDs in the central Apennines re-use pre-existing minor faults or shear fractures located in the footwall of large normal seismogenic faults and that no microstructural indicators can allow to uniquely distinguish between DGSDs and normal faults. Indeed, slip zones associated with both NFs and DGSDs in carbonate rocks are produced by similar deformation mechanisms.

Texte intégralDuring the Early Permian, the post-Variscan evolution of the present-day Alpine region was characterized by crustal extension combined with strong magmatic activity at different crustal levels, which finally led to the development of intracontinental extensional basins filled with volcanoclastic sediments (e. g. the Orobic Basin, N Italy). In the central Southern Alps (cSA), the opening of these basins was controlled by complex fault system that were active at the same time of plutons intrusion and volcanic activity at the surface. Relationships among magmatism, tectonics and hydrothermal activity related to the formation of ore deposits in the Early Permian so far have been only briefly addressed. This Ph.D. research project focuses on the investigations of the above described features, trying to consider the geological processes active in the Early Permian in an integrated scenario. Several Early Permian faults of the Orobic Basin have been investigated with special emphasis on the recognition of their original features, as they have exceptionally escaped most of the Alpine deformation. In the past, the architecture of Permian basins was described as horst-and-graben structures, formed in response to wrench tectonics developed during the activity of a megashear zone that led to the Pangea B to Pangea A transformation after the collapse of the Variscan orogen. However, thanks recent studies, a different fault architecture has been suggested to had controlled the opening of the Permian basins: a combination of Low-Angle Normal faults and High-Angle Normal Faults. The identified LANFs of the Orobic Basin represent the best site to study the interplay among tectonics and magmatism, as they are characterized by cataclastic bands sealed with cm to dm thick layers of dark, aphanitic tourmalinites. These latter are proof of fluids circulation channelled along higher permeability fault zones related to opening of the Orobic Basin. Such tourmaline breccias also crop out in the Trompia Valley (BS): several authors suggested that tourmalinites from Orobic Alps, tourmalinites from Trompia Valley together with uranium mineralization of Novazza - Vedello Valley are genetically linked. They are seen as products of a large-scale high-temperature hydrothermal system coeval with the Early Permian plutonic-volcanic activity and tectonism, which was also responsible for the emplacement of various types of magmatic-hydrothermal ore deposits in the Southern Alps (Sn-W, U-Mo-Zn, Fe carbonates, sulphides, quartz). However, their genesis has never been fully characterized and the connection between tourmalinites and U ore bodies has also not been deeply investigated so far. The tourmalinized faults were first noted in various sites of the cSA during the 90’s, when the tectonic importance of LANFs was not yet recognized. In this thesis, all the occurrences of tourmalinites are characterized, looking for the cause of the regional hydrothermalism in the context of intracontinental extension during the Early Permian. Furthermore, due to the likely connection with U ore deposits, the borosilicate study is proposed as tool for better understanding the genesis of the mineralizations. New field based structural analysis are combined with mineral and whole-rock geochemistry, geochronology, microstructural studies and boron- isotopic analysis of tourmalinites from different sectors of the study area, in order to evaluate the origin of these fluids. Results coming out from this study demonstrate, together with B isotope ratios, a temporal and genetical relationship between tourmalinites and Early Permian magmatism in the cSA. Furthermore, the geochemical data on trace elements provide more clues on a direct connection between tourmalinites and the U-mineralization. All these results are finally discussed in the frame of the interplay between tectonic, magmatic and ore generation processes that interested the present day cSA area in the Early Permian
