Introduction
My principal research interest is to study fault structure and mechanics by integrating fieldwork, virtual outcrops and rock mechanics experiments. I am also particularly interested in digital geological techniques, especially in virtual outcrop models construction and interpretation. In this period I am focussing on carbonate-hosted fault damage zones in the central Apennines and on fracture distribution on anticlines of the Zagros fold and thrust belt.

Article
Major advances in smartphones and tablets in terms of their built-in sensors (esp. cameras), available computational power and on-board memory are transforming the role of such devices into the key digital platform around which geological fieldwork is redesigning itself. This digital transition is changing how geoscientists collect and share multim...

Bedding-perpendicular joints striking parallel (longitudinal) and perpendicular (transverse) to both the axis of the hosting anticline and the trend of the foredeep-belt system are widely recognized in fold-and-thrust belts. Their occurrence has been commonly attributed to folding-related processes, such as syn-folding outer-arc extension, although...
Article

During earthquakes, fault rupture can involve multiple segments in synchronous or cascade mechanisms, leading to an increasing magnitude of the mainshock or rate of aftershocks. Since the seismogenic portions of faults are commonly inaccessible, studying the geometrical and mechanical interaction between exhumed fault segments can contribute to the...
Article
We combined structural data collected in the field and those obtained from a virtual outcrop model constructed from drone imagery, to perform Discrete Fracture Network (DFN) modelling and to characterize the fracture distribution within the damage zone of the low-displacement (∼50 m) carbonate-hosted Pietrasecca Fault (PF) (central Apennines, Italy...

Geotagged smartphone photos can be employed to build digital terrain models using structure from motion-multiview stereo (SfM-MVS) photogrammetry. Accelerometer, magnetometer, and gyroscope sensors integrated within consumer-grade smartphones can be used to record the orientation of images, which can be combined with location information provided b...

Understanding the factors controlling fracture frequency distribution can greatly improve the assessment of fluid circulation in fault damage zones, with evident implications for fault mechanics, hydrogeology and hydrocarbon exploration. This is particularly important for relay zones that are usually characterized by strong damage and structural co...
Presentation
Fractures constitute the main pathway for fluids in fault damage zones hosted in low-porosity rocks. Understanding the factors controlling fracture distribution is hence fundamental to better assess fluids circulation in fault damage zones, with evident implications for fault mechanics, hydrogeology and hydrocarbon exploration. Being usually charac...
Presentation
Fracture distribution controls fluids circulation in fault damage zones, with evident implications for fault mechanics, hydrogeology and hydrocarbon exploration. Being usually characterized by a strong damage and structural complexity, this is of particularly importance for relay zones. We investigated the fracture distribution within a portion of...

Full-text available
Minor fault geometry and kinematics within relay ramps is strongly related to the stress field perturbations that can be produced when two major fault segments overlap and interact. Here we integrate classical fieldwork and interpretation of a virtual outcrop to investigate the geometry and kinematics of subsidiary faults within a relay ramp along...
Presentation
A multiscale geometrical and kinematic characterization of fault zones is the starting point to understand fault mechanics, in particular that of potentially seismogenic faults. Fieldwork and seismological studies can provide pictures and kinematic characterization of faults at sub-regional scale (i.e. tens of kilometers). Until the advent of Digit...
Presentation
A fault zone is composed of one or multiple fault cores, which are located within a complex network of fractures and secondary slip surfaces (i.e., the damage zone) that determine the mechanical behaviour. For example, fractures within the damage zone control fluid circulation and have a strong impact on the elastic properties of the host rock. Fur...
Article
A great number of earthquakes occur within thick carbonate sequences in the shallow crust. At the same time, carbonate fault rocks exhumed from a depth < 6 km (i.e., from seismogenic depths) exhibit the coexistence of structures related to brittle (i.e., cataclasis) and ductile deformation processes (i.e., pressure-solution and granular plasticity)...
Presentation
The characterization of frictional properties and deformation mechanisms of carbonate–bearing normal faults is fundamental to characterize reservoir development and seismic hazard. We conducted 24 experiments on simulated calcite fault gouges made of powdered Carrara Marble. Experiments have been performed at room temperature with a biaxial apparat...
