Learning Objectives
The course aims to give a basic preparation about deformation of rocks and of rheological parameters that determine the type of deformation. Moreover, the course will give information about the techniques of analysis of structural data and their elaboration in order to reconstruct the tectonic evolution of studied areas.
Prerequisites
Basic geological knowledge
Teaching Methods
Frontal lessons and field excursions
Further information
The course includes some not mandatory excursions in the field to show some example of brittle and ductile deformations
Type of Assessment
Oral examination on the main arguments of the course. In particular will be verified the knowledge of Stress, strain and rheology, as well as on the deformative features on brittle and ductile geological contexts.
