Learning outcomes
Understanding the deformation mechanisms and rheological behavior of the rocks. Learning the analytical techniques of structural geology, with particular reference to their practical applications: characterization of frectured rock masses; earthquake geology; mining exploration and natural resources. Learning methods and tools to quantitatively describe deformation in rocks (stress and strain). Learn to recognize micro- and mesoscopic tectonic structures and interpret them mechanically and kinematic. Know the main numerical and analog modeling techniques with their practical applications.
Course contents
Techniques of structural geology and tectonics. Geophysical techniques: seismic reflection. First motion radiation pattern from a faulting event. Rheological behaviour of rocks. Principles of deformation of rocks: deformation mechanisms, brittle and ductile deformation. Stress and strain: the Mohr diagrams, stress and strain tensors. Tectonic regimes and structural styles. Extensional tectonics and normal faulting. Structural associations of normal faults and extensional structures. Extensional environments and regional examples. Compressional tectonics. Thrust deformation. Thrust systems: geometry of thrust faults, lateral and oblique ramps, back-thrusts, pop-up structures. Duplex and horses, imbricate stack, normal and out-of-sequence kinematic development of thrusts. Strike-slip tectonics. Strike-slip fault associations. Transpression and transtension. Transcurrent environments and regional examples. Inversion tectonics. Salt tectonics. Neotectonics. Faults, fractures and joints: features and analysis criteria. Rock mass properties and structural classifications.
Cross-sections. Geometrical techniques for reconstructing the deformation. Modelling the deformation of rocks. Numerical models. Analogue modelling. Applications to hydrocarbon and earthquake geology.
