As a first class of Geology, this teaching aims at providing the basis to understanding the Rock’s cycle, the genetic processes and the environments of genesis of the main rock types (sedimentary, igneous and metamorphic). The laboratory exercises point to the practise with identification and description of rock samples and to the drawing of basic stratigraphic sections. This class also provides the fundamentals of the main concepts of the Geological Sciences.

Lectures: Geology and Earth Sciences: applications to the social welfare; the dynamic Earth: genesis of the endogenous, exogenous and climatic systems; the different subjects of the Earth Sciences. The endogenous system: atoms, chemical elements and minerals; interior of the Earth; features and genesis of the magmatic rocks; features and genesis of the metamorphic rocks; the earth’s surface as results of the interplay between endogenous and exogenous systems: the plate tectonics. Earth deformations: faults, folds and other structures. Plate tectonics and orogeny. Earthquakes and volcanoes. The exogenous system: cratons, mountain ranges and ocean basins; biosphere, cryosphere, idrosphere, atmosphere; the sedimentary rocks: features and genesis; the climatic system: components and perturbations; elements of the climatic history of the Earth; the concept of relative and absolute geological time. Dynamics of the stratigraphic and sedimentary processes; the stratigraphic successions; strata and geometry of the successions; basic concepts of stratigraphy.
Practicals
Description and recognition of hand samples of the different types of rocks: magmatic (intrusive, effusive and pyroclastic), metamorphic (from low to high grade) and sedimentary (clastic, carbonaceous, chemical). Field- excursions. Stratigraphic exercises using the basic principles of stratigraphy on stratigraphic patterns

Lectures on the different topics of the course, practice on macroscopic rock samples, field excursions in order to introduce students to the observation of the outcrops and of the texture of the rocks.
