Aims and learning outcomes
The purpose of the course is to enable students to acquire knowledge, skills and abilities in the identification and management of:
- The types of natural materials of geologic origin;
- The chemical laws at the base of the distribution and properties of chemical elements into geomaterials;
- The chemical and physical processes at the basis of genesis and evolution of geomaterials;
- The environmental impact of geomaterials.

Evaluation
RULES OF VERIFICATION
Assessment will be through a final oral examination.
The assessment of learning provides for the assignment of a final grade.

COMMITMENT REQUIRED
The student will be required a commitment to:
- Actively participating in the course, following topics on the handouts, on recommended texts and on the reference websites;
- Understanding terminology and scientific concepts, and their application in the discussions during the course, in writing assignments, and in oral examinations;
- Knowledge of the name, location, type of volcanism and geological problems of volcanoes covered in the course;
- Having the ability to redraw the charts and diagrams, and to appropriately comment on the images presented in the course.

The main topics are:

1 Introduction to study of geological materials;
2 Structure and composition of the Earth, geochemical classification of elements, geochemical behavior of geomaterials, methods of sampling and analysis of geomaterials;
3.Characteristics and composition of minerals and rocks, origin and types of soils.
4. The geochemical magmatic cycle, partial melting, fractional crystallization, isotope geochemistry, environmental impact.

Detailed:

Introduction to geomaterials
• Structure and composition of the Earth, core, mantle, crust, atmosphere, hydrosphere, meteorites
• Minerals, chemical and physical properties, geochemical composition, polymorphism, classes of silicates, rock forming minerals
• Crystal-chemistry, isomorphism and vicariance, methods of sampling and analysis of geomaterials.
Types of rocks
• Sedimentary rocks, environment, types, classification, texture, structure
• Igneous rocks, petrographical and geochemical classification, volcanic activity, texture and structure
• Metamorphic rocks, metamorphic processes an types
• soils, chemical and physical weathering of geomaterials, types of soil
Geochemical magmatic cycle
• Origin of magma and its transfer through the crust toward the surface
• Types of magma and relationship with tectonic settings, petrology of volcanic rocks
• Trace elements, magmatic series
• Physical properties of magmas, viscosity, volatile contain, temperature
Isotope geochemistry
• Stable isotopes, hydrosphere and lithosphere, geo-thermometers
• Radiogenic isotopes, dating, magmatic sources, Solar system evolution
• Hazard assessment (geological survey, scenario building, integrated hazard mapping)
• Communicating volcanic risk information to vulnerable populations and decision makers
• Risk mitigation
Environmental Geochemistry
• Natural radioactivity, radon
• Impact of geomaterials on the environments and humans.

Materials and texts
The material used during the lectures and exercises will be made available to the student.
