SANFILIPPO ALESSIO (titolare) - 6 ECTS
TRIBUZIO RICCARDO - 6 ECTS

Students are expected to have acquired the basic concepts in petrography, trace element geochemistry, isotope geochemistry, geochronology and structural geology.

Students are expected to: (i) understand the relationships between magmatic/metamorphic processes and plate tectonics; (ii) analyze the rocks of mantle, magmatic and metamorphic origin at the outcrop scale; (iii) correlate structures and microstructures with geochemical data; (iv) acquire the main geological and petrological characteristics of the Alpine-Apennine belt.

State of the art knowledge of the composition, structure and architecture of Mid-Ocean Ridges. The fossil oceanic lithosphere (ophiolites). Structure and petrology of the subcontinental lithospheric mantle and the continental crust in different geodynamic settings. The classroom activity is combined with field excursions aimed at studying: (i) the Jurassic ophiolites exposed along the Alpine-Apennine belt, and (ii) the nearly complete section of continental crust of the Adria plate exposed in the Southern Alps close to the Insubric Line, which consist of the so called Ivrea-Verbano Zone and Serie dei Laghi.

The course consists of oral lectures, exercises in the field and exercises at the optical microscope. I particular, the rocks observed in the field will be the object of micro-structural investigations at the optical microscope. The course also includes some didactic seminars.

- Igneous and Metamorphic Petrology, Wiley, Myron G. Best
- Radiogenic Isotope Geology, Cambridge University Press, Alan P. Dickin
- Scientific articles indicated by teachers at the beginning of the course.

Oral exam dealing with the subjects explained during oral lectures and field/petrographic exercises. The student evaluation will also consider the use of an appropriate scientific language. There are two oral exams, corresponding to the two 6 CFU modules. The final evaluation is given by the average of the two evaluations; it is mandatory that both exams are evaluated sufficiently.
