CAUCIA FRANCA PIERA (titolare) - 6 ECTS

For the enjoyment of teaching it is necessary to have a good knowledge of inorganic chemistry (solid state; chemical bonds; coordination of transition metals and alkali metals oxidation numbers; Ionic rays; periodic table of the elements) and Physics (light; the visible package; wavelengths and frequencies; diffraction of light; Snell's law; total refraction).

The teaching is aimed at the recognition of the fundamental minerals of rocks and their description both morphological and structural, to the study of the chemical properties of minerals; The ability to differentiate the crystalline state from the amorphous state.

The systematic classification of the fundamental minerals of the rocks is treated, giving greater importance to the silicate minerals.
The morphology and crystal structure of minerals. Simple forms and associations.

Crystachemistry: Isomorphism and polymorphism in minerals; complete solid solutions and miscibility gaps; Examples in rocks minerals. Physical properties of minerals and their importance in recognizing the various phases. Genesis of Minerals. Paragenesis.

Frontal lectures carried out through the use of Power Point presentations and in-depth information on the blackboard. Minerals will also be brought into the classroom for their recognition and morphological description. Tutorials on models of crystal Wood. Recognition of complete symmetry, of simple forms with relative multiplicity. Stereographic projections and Miller indices of simple and composed forms belonging to the Holedral classes of the 7 crystalline systems.

Didactic materials provided by the teacher
KLEIN C. (2004): Mineralogy Zanichelli Ed.

The exam takes place in written form, in a single test for both modules. It consists of 10 open questions and two exercises, distributed equally between the two modules. Every question and every exercise are assessed up to three points the exercises are those proposed in lecture, in particular they relate to the recognition of models, stereographic projections of complete symmetry and simple forms, reading and description of Phase diagrams, classification of rocks and their description, as from material available on Kiro or distributed in lecture.

The following material is required for practical exercises: compass, coloured pencils.
For frontal lessons It is useful to have a periodic table of the elements.
