Descriptive mineralogy: crystal shape, luster, hardness, cleavage. Systematic mineralogy: native elements, sulphides, oxides, hydroxides, carbonates, sulphates, phosphates, borates, silicates. Rock-forming minerals. Ore minerals. Gems and pigments. Industrial minerals. Cement and concretes. Ceramics. An introduction to plate tectonics and petrogenetic processes: the rock cycle. An introduction to the geochemical classification of elements. The chemical composition of rocks, diagrams for the classification and discrimination; trace elements. Field relationships and geometrical relations for volcanic and plutonic igneous rocks. Petrogenetic processes and phase diagrams: topology of binary diagrams. Macroscopic description and classification of igneous rocks. Rock forming minerals in igneous rocks and the classification of Streckeisen. Metamorphic rocks: stress, strain, and metamorphism. Factors controlling metamorphism and types of metamorphism. The Metamorphic Facies and subdivisions in the Pressure-Temperature diagram. Rock forming minerals in metamorphic rocks and classifications. Dimension stones and historical uses. The students will practice in the labortory the description of the most common minerals and and textures and mineral assemblages of most common igneous and metamorphic rocks, to be discussed in exams.
