Introduction: geological materials characterization (bulk analysis vs microanalysis), analytical chemistry concepts
Applied petrography: the petrographic microscope in the study of composite materials as ceramics, concrete and mortars
Diffraction techniques: interaction ray-x with matter, geometric conditions, intensities and structure determination
Spectroscopy techniques: interaction matter-radiation, X-ray absorption and emission spectroscopies, vibrational and mass spectroscopies
Microanalysis: introduction, interaction electron-matter, electron microscopy, electron, nuclear and photonic microprobe, ablation methods: detention limits, precision, spatial resolution and applications
Element and isotopic geochemistry: geochemical behaviour of the elements, sampling and preparation of samples, main analytical methods, treatment a presentation of the data
Physical properties of rocks in what concern to permeability vs. porosity and rock tension, strength and deformability

Teaching Methods
The teaching will be done by theoretical lectures and experimental activities, encouraging critical thinking of the students. In the former, the principles and the concepts associated with each method and technique are provided. In the experimental activities will be provided the tools that will allow the students to use the same methodologies and interpret the results. The University of Évora has the necessary infrastructures, namely equipment for sample preparation and physical-mechanical characterization in the Department of Geosciences and analytical techniques in the Laboratory HERCULES.
Members of the faculty of the University of Évora will present the classes, occasionally being invited guest speakers to teach specific topics in the form of seminars.
The evaluation will consider an exam (50%), a laboratory component (30%), writing a review paper (15%) and oral presentation (5%).
