Learning objectives
The aim of the course is to generate the essential knowledge for a suitable learning of all the disciplines related to the Earth Sciences. Minerals are, in fact, fundamental components of the rocks, which, in turn, are derived from particular geological processes, each with its own evolution. Knowing structure, symmetry and chemical composition of minerals means understanding in a deeper way the processes in earth science.
The students will be able, from the practical point of view, to recognize massive minerals and their crystal system. From the theoretical point of view, they will know the main families (silicates and non-silicates) of rock-forming minerals.
