Contents
Plate tectonics is the unifying, general theory framing all the Earth phenomena and processes. The Global Tectonic course is focused in understanding the tectonic processes at global scale, as related to the onset and evolution of the sedimentary basins and to the geological processes responsible for geological hazard in the presently changing world.

Educational objectives
Students attending the course are expected to have a comprehensive view of the global tectonics processes, understanding in particular:
- how sedimentary basins are formed in different tectonic framework;
- which are the main subsidence mechanisms, as related to the rheology of the lithosphere and mantle;
- which are the main hazard sources related to natural processes and how human activity may affect these processes.
Prerequisites
Basic geology and geophysics, acquired during the first level degree courses.
Teaching methods
Lectures (frontal lessons), alternated with open class discussions on selected, relevant topics of the course.
Other information
All teaching materials are available for download on the Uni-Studium Platform, which is also used as the main tool for teacher-students communications.
The teacher can be also contacted at the following e-mail address: massimiliano.barchi@unipg.it.
Learning verification modality
At the end of the course, the learning of the student will be assessed through a multiple answers test (or an oral exam if the written text is not possible, e.g. for pandemic).
During the course, open discussion of the single topics will allow continuous assessment of class participation. The discussions will also allow the teacher to evaluate the class heterogeneities and integrative explanations on specific geological pre-requisites (e.g. basic geology, basic geophysics, etc).
