This course is aimed to provide the students with the knowledge and skills necessary to investigate in depth the processes leading to the genesis and diversification of igneous and metamorphic rocks in different geodynamic enviroments and their role in the evolution of the continental crust. To this purpose, the course introduces a variety of both modern and traditional petrologic tools and approaches.
Upon successful completion, students will be able to:
- understand and describe advanced petrological processes;
- synthesize, interpret and critically evaluate petrological literature;
- analyze and interpret petrological data to provide constraints on relevant research problems in Earth Sciences;
- communicate results effectively to a peer audience.
This course consists of a series of lectures, complimented by practical sessions and one-day field trip, on selected topics and investigation tools from the discipline areas of igneous and metamorphic petrology. The course combines advanced theory in these discipline areas with case studies and applications related to current research topics, with a main focus on the origin and evolution of the continental crust.
The module of Igneous Petrology focuses on investigation of magmatic processes, from genesis to emplacement and solidification of the magma in various geodynamic and tectonic settings, with a special emphasis on plutonic systems.
The module of Metamorphic Petrology deals with the formation of metamorphic rocks in different crustal environments, with a main focus on the problems associated with estimates of metamorphic conditions and the use of these constraints in investigating the evolution of the Earth's crust.
Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.
