As for the basics of Mineralogy, the student must possess knowledge of the crystalline state. Symmetry in crystals. The crystal lattice. Physical properties of minerals. Structure of minerals: coordination polyhedra. in compact packaging structures. Polymorphic transformations in minerals. Vicariance and isomorphism. Native elements; carbonates; sulphates; Oxides and hydroxides; Sulphides. Classification of silicates. Nesosilicate. Sorosilicati. Inosilicates. Phyllosilicates. Tectosilicates.

Teaching methods

Lectures in "ex cathedra" mode integrated with practical activities both in class and lab. Field activities and visits to industrial sites are also part of the course. Attendance to the course is mandatory.

Assessment methods

Oral examination at the end of the course. The oral test is composed of three general questions which regards the three distinct parts of the course: 1.Systematics of the raw materials; 2.Mining, processing and characterization of the raw materials; 3.Application of the raw materials. The topic of the first question is up to the student. The subject of the following questions will be up to the teacher and will regard the two sections of the course left. Students may also benefit the option to present a written report on one the three sections that will be discussed during the oral test. The prsentation will be followed by questions that regard the two sections of the course left. If the student answers each question correctly, the final score will be 30/30. A final question will allow the student to obtain the "laude (30/30 e lode)". Any error made or no answer is penalized by 1-3 points depending on the severity of the mistake. E.g. if the student makes two major errors, the penalty will be 6 points and the final score will be 24/30.
