Course program
Definition of a mineral. Brief outline of the history of mineralogy. Genetic processes of minerals. Crystalline and amorphous state. Physical properties of minerals. Chemical bonds in minerals. Ionic radii and coordination polyhedra. Solid solutions: isomorphic substitutions. Crystal-chemical formulae. Polymorphism: mineral stability as a function of PTX parameters. Crystal morphology and symmetry. Periodicity, lattice and unit cell. Systematic mineralogy: classification; the most relevant minerals (silicates and non-silicates). Optical properties: principles (anisotropy/ isotropy; refractive indices; double refraction and birefringence; optical indicatrices, optical sign and interference figures of isotropic, uniaxial and biaxial minerals). Practice of mineral identification both at the macroscopic scale and in transmitted light microscopy. Brief description of main geomaterials utilized in pre-Industrial times for applications in the Cultural Heritage field (glass; ceramics; metals and metal alloys).
