Abstract:
Abstract Carlin-type gold deposits in northern Nevada are inferred to overlie concealed late Eocene plutons, which are increasingly thought to have provided magmatic input to the meteoric water-dominated fluids from which the gold was precipitated. The Larderello, Monte Amiata, and Latera geothermal systems in the Northern Apennines of southern Tuscany and northern Latium, central Italy, may represent Pliocene to present-day analogues because of their demonstrated association with subsurface plutons and jasperoid-hosted antimony-gold mineralization. The plutons, which at depths of >5–7 km remain at least partially molten, continue to supply heat and magmatic fluids to the meteoric water-dominated geothermal systems. Formerly mined antimony deposits of Pliocene or younger age are exposed on the peripheries of the CO2 ± H2S-emitting geothermal systems, and antimony sulfides are still actively precipitating. Stibnite and submicroscopic gold in disseminated pyrite, along with Au/Ag of <0.5 and anomalous As, Hg, Tl, and Ba values, accompanied jasperoid formation in the Northern Apennines systems. Carlin-type mineralization in northern Nevada and the antimony-gold mineralization in the Northern Apennines are hosted by permeable carbonate rocks, particularly stratabound breccias, where they are intersected by steep normal or oblique-slip faults and confined beneath tectonically emplaced hydrologic seals. The Northern Apennines antimony-gold mineralization formed at shallow, epithermal depths, like that recently recognized in the southern Carlin trend of northern Nevada. Although underexplored, the Northern Apennines gold prospects are unlikely to ever attain the giant status of the Carlin-type deposits in northern Nevada, probably because of lower magmatic fertility (ilmenite-series rather than magnetite-series magmatism) and host-rock receptivity (less reactive iron). Nevertheless, shallow carbonate-rock aquifers within high-temperature, intrusion-related geothermal systems, be they extinct or still active, may be prospective for Carlin-style gold deposits.

Abstract. We studied the Zuccale Fault (ZF) on Elba, part of the Northern Apennines, to unravel the complex deformation history that is responsible for the remarkable architectural complexity of the fault. The ZF is characterized by a patchwork of at least six distinct, now tightly juxtaposed brittle structural facies (BSF), i.e. volumes of deformed rock characterized by a given fault rock type, texture, colour, composition, and age of formation. ZF fault rocks vary from massive cataclasite to foliated ultracataclasite, from clay-rich gouge to highly sheared talc phyllonite. Understanding the current spatial juxtaposition of these BSFs requires tight constraints on their age of formation during the ZF lifespan to integrate current fault geometries and characteristics over the time dimension of faulting. We present new K–Ar gouge dates obtained from three samples from two different BSFs. Two top-to-the-east foliated gouge and talc phyllonite samples document faulting in the Aquitanian (ca. 22 Ma), constraining east-vergent shearing along the ZF already in the earliest Miocene. A third sample constrains later faulting along the exclusively brittle, flat-lying principal slip surface to < ca. 5 Ma. The new structural and geochronological results reveal an unexpectedly long faulting history spanning a ca. 20 Myr time interval in the framework of the evolution of the Northern Apennines. The current fault architecture is highly heterogeneous as it formed at very different times under different conditions during this prolonged history. We propose that the ZF started as an Aquitanian thrust that then became selectively reactivated by early Pliocene out-of-sequence thrusting during the progressive structuring of the Northern Apennine wedge. These results require the critical analysis of existing geodynamic models and call for alternative scenarios of continuous convergence between the late Oligocene and the early Pliocene with a major intervening phase of extension in the middle Miocene allowing for the isostatic re-equilibration of the Northern Apennine wedge. Extension started again in the Pliocene and is still active in the innermost portion of the Northern Apennines. In general terms, long-lived, mature faults can be very architecturally complex. Their unravelling, including understanding the dynamic evolution of their mechanical properties, requires a multidisciplinary approach combining detailed structural analyses with dating the deformation events recorded by the complex internal architecture, which is a phenomenal archive of faulting and faulting conditions through time and space.

Abstract:
For its particular position and the complex geological history, the Northern Apennines has been considered as a natural laboratory to apply several kinds of investigations. By the way, it is complicated to joint all the knowledge about the Northern Apennines in a unique picture that explains the structural and geological emplacement that produced it. The main goal of this thesis is to put together all information on the deformation - in the crust and at depth - of this region and to describe a geodynamical model that takes account of it. To do so, we have analyzed the pattern of deformation in the crust and in the mantle. In both cases the deformation has been studied using always information recovered from earthquakes, although using different techniques. In particular the shallower deformation has been studied using seismic moment tensors information. For our purpose we used the methods described in Arvidsson and Ekstrom (1998) that allowing the use in the inversion of surface waves [and not only of the body waves as the Centroid Moment Tensor (Dziewonski et al., 1981) one] allow to determine seismic source parameters for earthquakes with magnitude as small as 4.0. We applied this tool in the Northern Apennines and through this activity we have built up the Italian CMT dataset (Pondrelli et al., 2006) and the pattern of seismic deformation using the Kostrov (1974) method on a regular grid of 0.25 degree cells. We obtained a map of lateral variations of the pattern of seismic deformation on different layers of depth, taking into account the fact that shallow earthquakes (within 15 km of depth) in the region occur everywhere while most of events with a deeper hypocenter (15-40 km) occur only in the outer part of the belt, on the Adriatic side. For the analysis of the deep deformation, i.e. that occurred in the mantle, we used the anisotropy information characterizing the structure below the Northern Apennines. The anisotropy is an earth properties that in the crust is due to the presence of aligned fluid filled cracks or alternating isotropic layers with different elastic properties while in the mantle the most important cause of seismic anisotropy is the lattice preferred orientation (LPO) of the mantle minerals as the olivine. This last is a highly anisotropic mineral and tends to align its fast crystallographic axes (a-axis) parallel to the astenospheric flow as a response to finite strain induced by geodynamic processes. The seismic anisotropy pattern of a region is measured utilizing the shear wave splitting phenomenon (that is the seismological analogue to optical birefringence). Here, to do so, we apply on teleseismic earthquakes recorded on stations located in the study region, the Sileny and Plomerova (1996) approach. The results are analyzed on the basis of their lateral and vertical variations to better define the earth structure beneath Northern Apennines. We find different anisotropic domains, a Tuscany and an Adria one, with a pattern of seismic anisotropy which laterally varies in a similar way respect to the seismic deformation. Moreover, beneath the Adriatic region the distribution of the splitting parameters is so complex to request an appropriate analysis. Therefore we applied on our data the code of Menke and Levin (2003) which allows to look for different models of structures with multilayer anisotropy. We obtained that the structure beneath the Po Plain is probably even more complicated than expected. On the basis of the results obtained for this thesis, added with those from previous works, we suggest that slab roll-back, which created the Apennines and opened the Tyrrhenian Sea, evolved in the north boundary of Northern Apennines in a different way from its southern part. In particular, the trench retreat developed primarily south of our study region, with an eastward roll-back. In the northern portion of the orogen, after a first stage during which the retreat was perpendicular to the trench, it became oblique with respect to the structure.

Abstract:
The Northern Apennines (NA) chain is the expression of the active plate margin between Europe and Adria. Given the low convergence rates and the moderate seismic activity, ambiguities still occur in defining a seismotectonic framework and many different scenarios have been proposed for the mountain front evolution. Differently from older models that indicate the mountain front as an active thrust at the surface, a recently proposed scenario describes the latter as the frontal limb of a long-wavelength fold (> 150 km) formed by a thrust fault tipped around 17 km at depth, and considered as the active subduction boundary. East of Bologna, this frontal limb is remarkably very straight and its surface is riddled with small, but pervasive high- angle normal faults. However, west of Bologna, some recesses are visible along strike of the mountain front: these perturbations seem due to the presence of shorter wavelength (15 to 25 km along strike) structures showing both NE and NW-vergence. The Pleistocene activity of these structures was already suggested, but not quantitative reconstructions are available in literature. This research investigates the tectonic geomorphology of the NA mountain front with the specific aim to quantify active deformations and infer possible deep causes of both short- and long-wavelength structures. This study documents the presence of a network of active extensional faults, in the foothills south and east of Bologna. For these structures, the strain rate has been measured to find a constant throw-to-length relationship and the slip rates have been compared with measured rates of erosion. Fluvial geomorphology and quantitative analysis of the topography document in detail the active tectonics of two growing domal structures (Castelvetro - Vignola foothills and the Ghiardo plateau) embedded in the mountain front west of Bologna. Here, tilting and river incision rates (interpreted as that long-term uplift rates) have been measured respectively at the mountain front and in the Enza and Panaro valleys, using a well defined stratigraphy of Pleistocene to Holocene river terraces and alluvial fan deposits as growth strata, and seismic reflection profiles relationships. The geometry and uplift rates of the anticlines constrain a simple trishear fault propagation folding model that inverts for blind thrust ramp depth, dip, and slip. Topographic swath profiles and the steepness index of river longitudinal profiles that traverse the anti- clines are consistent with stratigraphy, structures, aquifer geometry, and seismic reflection profiles. Available focal mechanisms of earthquakes with magnitude between Mw 4.1 to 5.4, obtained from a dataset of the instrumental seismicity for the last 30 years, evidence a clear vertical separation at around 15 km between shallow extensional and deeper compressional hypocenters along the mountain front and adjacent foothills. In summary, the studied anticlines appear to grow at rates slower than the growing rate of the longer- wavelength structure that defines the mountain front of the NA. The domal structures show evidences of NW-verging deformation and reactivations of older (late Neogene) thrusts. The reconstructed river incision rates together with rates coming from several other rivers along a 250 km wide stretch of the NA mountain front and recently available in the literature, all indicate a general increase from Middle to Late Pleistocene. This suggests focusing of deformation along a deep structure, as confirmed by the deep compressional seismicity. The maximum rate is however not constant along the mountain front, but varies from 0.2 mm/yr in the west to more than 2.2 mm/yr in the eastern sector, suggesting a similar (eastward-increasing) trend of the apenninic subduction.

Abstract:
The objective of this study is to provide an innovative methodology for the estimation of climate change impacts on groundwater resources. This methodology has been applied to the Tresinaro stream catchment (147 km2) in the northern Apennines (Italy), and to the main water source of the stream, the Mulino delle Vene springs (Carpineti, Reggio Emilia province). These springs outflow from a fractured aquifer hosted in a sandstone plateau, and the mean discharge is 96.8 l/s. Firstly, some finite elements models of the fractured aquifer feeding the Mulino delle Vene springs have been developed, with the codes FEFLOW and TRANSIN, in order to investigate the groundwater flow system. In particular, some sensitivity analyses and transient state simulations have been carried out, and a range of calibrated conductivity values for the fractured rock masses (between 1.16 x 10-4 m/s and 1.16 x 10-7 m/s) has been identified. Moreover, a physically based surface-subsurface flow model has been developed for the Tresinaro stream catchment with the finite elements code HydroGeoSphere. In the second place, some rainfall-runoff models of the Mulino delle Vene springs have been built and calibrated on the daily springs discharge data. Then, the calibrated and validated models have been combined with climate change scenarios from five Regional Climate Models. Considering the results of this study, it is very likely that, in the next future, groundwater flow rates of the Mulino delle Vene springs will decrease, especially during the low flow period, exacerbating the water stress condition in the area (e.g. maximum discharge is likely to decrease by the 26.3% in September). The results of this analysis represent a first answer to the lack of researches in the field of climate change and groundwater in Italy. The developed methodology can be easily applied to other areas.

Abstract:
This PhD thesis focuses on the validation of an objective method to define paleocurrent directions in turbiditic systems: the anisotropy of magnetic susceptibility (AMS). The final purpose of this study is to calibrate paleocurrent directions estimated with this geophysical method to directions estimated from classic sedimentological indicators, and therefore verify the applicability of this method to cases where sedimentological paleocurrent indicators are absent such as in drill cores. Two selected turbiditic units outcropping in the northern Apennines, the Marnoso Arenacea Formation (Miocene, northern Apennines) and on the Castagnola Formation (Oligo-Miocene, Tertiary Piedmont Basin), were investigated. These basins have different depositional settings: the Marnoso Arenacea Formation filled a foredeep basin nearly 200 km long and 60 km wide, whereas the Castagnola Formation filled an episutural basin 6 km long and 4 km wide. AMS analyses were successfully applied to both formations on a total of 853 samples taken in a wide range of depositional intervals selected by means of detailed sedimentological analyses, and were successively cross-validated by direct estimates of flow directions from sedimentological indicators (ripple marks, flute marks, etc.). In the Marnoso Arenacea Formation, a robust correlation between magnetic fabric and paleocurrent directions obtained from sedimentological indicators was found in massive, parallel-laminated, and cross-laminated sandstones. These depositional intervals show well-clustered AMS data with an overall flow-aligned fabric. Instead, highly dispersed AMS fabrics are apparently common in convoluted and undulated sandstones as well as in debrites, suggesting depositional processes that partially prevented grains’ orientation (e.g., en masse freezing) or post-depositional processes that disrupted the original current-induced fabric (e.g., post-depositional dewatering). AMS fabrics typical of deposition in standing water was observed in the hemipelagites of the Castagnola Formation. Instead, in the fine-grained sediments of the Marnoso Arenacea Formation (White Marlstone beds), an AMS fabric interpreted as current-induced was observed and interpreted as due to muddy contourites. The study on the Castagnola Formation was carried out primarily to evaluate the effects of basin confinement on turbidity flow dynamics. In this small, confined turbidite system, we observed a strong correlation between magnetic fabric and bed-thickness distribution whereby beds thicker than ~1.20 m show high magnetic fabric variability and maximum susceptibility axes dispersion, whereas beds thinner than ~1.20 m show better developed magnetic fabrics with maximum susceptibility axes oriented consistently parallel to the mean paleoflow direction from flute casts. We believe that ~1.20 m represents a thickness threshold separating large flows that covered the entire basin floor interacting in a complex fashion with the basin’s margins from small volume flows that did not interact with the basin’s margins and produced better-defined flow-aligned AMS fabrics. Potential future developments of this thesis are: (1) deepening of our understanding on the relationships between grains’ orientations and magnetic minerals that contribute to the AMS signal by means of textural analyses, neutron diffraction and x-ray tomography. Preliminary results indicate that paramagnetic muscovite principally controls the observed current induced AMS fabric; (2) testing the AMS method on drill core samples, where flow marks (i.e., flute casts) are either absent or non-observable.

Abstract:
Thrust fault-related folds in carbonate rocks are characterized by deformation accommodated by different structures, such as joints, faults, pressure solution seams, and deformation bands. Defining the development of fracture systems related to the folding process is significant both for theoretical and practical purposes. Fracture systems are useful constrains in order to understand the kinematical evolution of the fold. Furthermore, understanding the relationships between folding and fracturing provides a noteworthy contribution for reconstructing the geodynamic and the structural evolution of the studied area. Moreover, as fold-related fractures influence fluid flow through rocks, fracture systems are relevant for energy production (geothermal studies, methane and CO2 , storage and hydrocarbon exploration), environmental and social issues (pollutant distribution, aquifer characterization). The PhD project shows results of a study carried out in a multilayer carbonate anticline characterized by different mechanical properties. The aim of this study is to understand the factors which influence the fracture formation and to define their temporal sequence during the folding process. The studied are is located in the Cingoli anticline (Northern Apennines), which is characterized by a pelagic multilayer characterized by sequences with different mechanical stratigraphies. A multi-scale analysis has been made in several outcrops located in different structural positions.

Abstract:
Thrust fault-related folds in carbonate rocks are characterized by deformation accommodated by different structures, such as joints, faults, pressure solution seams, and deformation bands. Defining the development of fracture systems related to the folding process is significant both for theoretical and practical purposes. Fracture systems are useful constrains in order to understand the kinematical evolution of the fold. Furthermore, understanding the relationships between folding and fracturing provides a noteworthy contribution for reconstructing the geodynamic and the structural evolution of the studied area. Moreover, as fold-related fractures influence fluid flow through rocks, fracture systems are relevant for energy production (geothermal studies, methane and CO2 , storage and hydrocarbon exploration), environmental and social issues (pollutant distribution, aquifer characterization). The PhD project shows results of a study carried out in a multilayer carbonate anticline characterized by different mechanical properties. The aim of this study is to understand the factors which influence the fracture formation and to define their temporal sequence during the folding process. The studied are is located in the Cingoli anticline (Northern Apennines), which is characterized by a pelagic multilayer characterized by sequences with different mechanical stratigraphies. A multi-scale analysis has been made in several outcrops located in different structural positions. This project shows that the conceptual sketches proposed in literature and the strain distribution models outline well the geometrical orientation of most of the set of fractures observed in the Cingoli anticline. On the other hand, the present work suggests the relevance of the mechanical stratigraphy in particular controlling the type of fractures formed (e.g. pressure solution seams, joints or shear fractures) and their subsequent evolution. Through a multi-scale analysis, and on the basis of the temporal relationship between fracture sets and their orientation respect layering, I also suggest a conceptual model for fracture systems formation.

Abstract:
Jonas of Bobbio, writing in the mid-seventh century, was not only a major Latin monastic author but also a historic figure in his own right. Born in the ancient Roman town of Susa in the foothills of the Italian Alps, he became a monk of Bobbio, the monastery founded by the Irish abbot Columbanus, soon after the saint’s death. He became archivist and personal assistant to successive Bobbio abbots, traveled to Rome to obtain the first papal privilege of immunity, and served as a missionary on the northern borderlands of the Frankish kingdom, where he wrote his Vita Columbani, one of the most influential works of early medieval hagiography. As abbot of a community in the far north of the Frankish kingdom, Jonas was part of an extensive monastic network that stretched from the English Channel to the Italian Apennines. By the time of Jonas’s death toward the end of the seventh century, the monastic landscape of this region had been transformed. This was the result of a socioreligious revolution, initiated by Columbanus (d. 615) and continued by his Frankish disciples in the decades after his death. Columbanus established a cluster of monasteries in the Vosges forests of Burgundy in the last decade of the sixth century, chief among them Luxeuil. During the seventh century, Luxeuil, its abbots, and the Merovingian royal court in Paris spearheaded an unprecedented monastic movement in Merovingian Gaul that would transform the interrelationship between religious and secular authorities in the Early Middle Ages.
